Why doesn’t the navigator turn on and show no signs of life? The GPS navigator does not see satellites. The navigator does not respond to the power button


) V Lately have become necessary not only for motorists, but also for pedestrians, thanks to their good ability to build walking routes.

But quite a lot of users have to deal with the fact that the GPS system on Android does not work or does not work well.

This may result in problems different types, depending on what exactly caused the breakdown.

Definition

What is GPS? This is a navigation system - strictly speaking, GPS/GLONASS is a navigation module that allows you to use many applications that use navigation.

Problems

But in some cases, certain problems may be detected in the operation of such a module. Their nature is different, but they equally interfere with working with the system:

  • Complete inability to determine locations;
  • Inaccurate location determination;
  • Slow data update or complete absence updates (for example, you move in space or turn around, but the pointer on the map does not change its position for a long time).

Most problems can disappear on their own when you restart or when you move to another area of ​​the map.

But if this does not happen, then you need to know what caused them and how to eliminate them.

Possible reasons

There can be many reasons for this type of problem. But all of them can be divided into two large groups - hardware problems and software problems.

We talk about hardware problems when the defect is present in the physical navigation module itself, and about software problems when something is incorrectly configured in the software of a smartphone or tablet.

Important! Problems software type enough easy to set up and fix yourself. When we're talking about about hardware failures, it is better to entrust the matter to a service center, since for a non-specialist the repair process can be quite complicated. And there is a risk of making the situation worse.

Hardware

One of the most common problems occurs when starting the module for the first time, that is, when you first launch an application that uses GPS on a new smartphone.

Within 15-20 minutes, geolocation may not work, nothing will happen, the location will not be determined.

When you first start it normal condition, but this should not happen again in the future.

A similar situation may arise if you have traveled a significant distance, for example, moved to another country or region, with the navigation module turned off.

In this case, when he first starts in a new place, he will also need time to “think.”

The problem may also occur when starting on high speed, for example, while driving a car - in this case, the module will “slow down” for the first time after switching on.

Keep in mind that in buildings, indoor navigation will not be carried out.

Your approximate location in the building is determined using the zone layout wireless internet and towers mobile operators, but not GLONASS.

Software

The GLONAS module can be disabled through the phone settings; often on new models it is not enabled by default.

Therefore, many beginners who are not accustomed to using Android do not turn it on before starting to use navigation applications.

By the way, this type notifies the user that he needs to enable navigation.

Inaccurate location determination may be due to the characteristics of the zone. The system does not work equally well in all areas due to the nature of satellite operation.

There are “blind” zones that the navigator misses or does not detect accurately. It is impossible to fight this.

Elimination

Troubleshooting is usually quite simple.

But if, after taking all of the above measures, the problem has not been resolved, it is possible that the problem is a faulty module and it requires replacement under conditions service center.

Hardware

There are no ways to “cure” the program freezing after the first launch of the navigation module.

The user just needs to wait about 15-20 minutes after the first launch of the application - during this time, the electronic components of the navigation device will adjust to the current operating conditions and the location will be determined.

That is why it is recommended to run this module for configuration immediately after purchasing a phone, so as not to wait in a situation where you need it urgently.

Software

Turning on navigation on your smartphone is quite simple. Most often, the application itself “asks” whether to enable navigation when it is disabled.

Then you need to click on “YES” or “OK” in the pop-up window, and the application itself will enable geolocation.

If such a notification does not appear, enable it manually, following the algorithm:

1 On the unlocked screen, on the desktop, pull out the menu, making a sliding movement from the top border of the screen down;

2 A menu with basic device settings will appear.– find the icon in it Geodata/Geodata transmission/Geolocation/Location determination or the like;

3 Click on it to make the icon active.

Instructions

Recovery car GPS navigators can be done in two ways: by downloading new firmware and without flashing, using the simplest SOFT-Reset. As for the first method, everything is more or less clear here, since flashing a navigator is completely similar to flashing an ordinary one cell phone, smartphone or communicator. To do this, you will need to download an archive from the Internet to your computer. suitable version firmware and unpack it using an unzip tool.

After this, you need to remove the memory card from the navigator, insert it into the card reader and copy the downloaded file with the firmware to the root directory. Then you should remove the card from the device and insert it back into the navigator.

Now you need to turn on the device and wait for a dialog box to appear asking whether you should start flashing. After your consent, the flashing of your car “friend” will begin. When the installation is complete, click the “Ok” button, after which a window will appear on the navigator screen with further instructions and instructions. This will complete the restoration of the navigator.

Soft reset Setting the navigator to the factory settings that the navigator originally had is called SOFT-Reset. To restore the GPS navigator in this way, you need to go to ResidentFlash, and then to JBSA4UI, where in the jbssetting.ini and jbssetting.ini.bak files in the DefaultSetting=0 line, change “0” to “1”.

After this, restart the navigator and go to the “Settings” - “Info” folder. At the bottom you will see 3 icons: “ USB Settings", "Navigation path" and Werkseins..., the last of which is SOFT-Reset, that is, returning to factory settings. Click on it. After this, a message will appear: “Are you sure you want to restore factory settings?” Click Yes. After some time, the original parameters will return, therefore, your navigator will be restored.

There are times when you need to clean or restore your phone or tablet. This happens if you need to sell a device or give it away, or just great amount no more applications needed. IN in this case You need to reset the settings to factory settings.

Yandex Navigator is confidently among the leaders in the ranking of navigation applications for mobile devices. A side effect of this popularity is a large number of difficulties when using. Let's look at the most common complaints and try to fix them.

Unfortunately, this is very vague information, which can be attributed to dozens of reasons, including the user’s inability to run the program and real-life geolocation failures in some areas. Therefore, let's look at the situation in more detail to highlight various aspects problems, not a trivial lack of knowledge about how a smartphone works.

In this material we will limit ourselves to the difficulties that occur when using navigation from Yandex.

The navigator cannot start correctly

The application was installed correctly, but does not even start: it displays error messages and crashes immediately after launch. The reason may be failures when installing the program on the smartphone.

By system requirements Almost any modern device supports Yandex Navigator, so the option with a lack of resources is extremely rare. This can be indicated by constant freezes and long pauses even before basic actions.

The smartphone may not be able to handle the application if it has less than half a gigabyte of RAM installed. For example, 256 MB is very little by modern standards.

As for the first case, you need to delete the program through the phone settings, and then re-install it. So, in Android OS you can use Play Store. If the crash was due to an error during installation, reinstalling will fix the problem.

Why does the program need an Internet connection?

Yandex Navigator can also work if you first prepare the program for this mode. In particular, you need to download to your smartphone the very maps that will be used to display your location without access to the Internet. This can be done from the application itself. Open the “Download maps” section in the menu, then specify the required city. If you are lucky and there is a map, download it.

It is worth noting that Yandex maps on the territory of the Russian Federation, Ukraine and many other countries have very decent coverage, so there is a high probability that there will be no difficulties at this stage.

  1. Before downloading, switch to WiFi, since some cards are large in size.
  2. True, it still won’t be possible to completely remove the connection to the Internet, so formally Yandex Navigator really only works online.

The fact is that although the maps are stored in the smartphone, you still need a connection to plot a route and search in the immediate vicinity. To some extent, preliminary calculation of the route helps - then you can move along it without communication. One way or another, exchange via the Internet will be significantly reduced, and the speed of the program will increase.

Of course, without an Internet connection, Navigator will not be able to download useful information, like traffic information. Just in case, check: if they are not displayed, perhaps the traffic light image in the corner is currently gray. If so, click on it - the traffic light will be activated and will display the traffic situation in color. And a digital display is used to show traffic congestion from 0 to 10.

There is a route, but the Navigator does not track movement along it

  1. First you need to make sure that receiving geodata is enabled.
  2. Then check your Internet connection and its speed (for example, open a website or two in your browser).
  3. If activated, the Internet is connected, but the program refuses to display the movement, try exiting the application and re-entering it.
  4. If it doesn't work, force stop special button from the settings section where applications are shown (the procedure is almost the same for Android and iOS). Launch Navigator again.

If it refuses to drive again, restart your smartphone. Have you tried everything but to no avail? Reinstall the program. Although it usually doesn’t come to this, Yandex programmers have written a good application.

Let’s imagine that even such serious measures did not help. In this case it remains the hard way– stop using Yandex Navigator on this particular smartphone. Since it’s not destiny for them to work together, use analogues.

Voice search crashes

There are several options here:

  • The microphone may be broken.
  • Or the Internet connection speed is not enough.
  • Or maybe the surroundings are not quiet enough - the street is noisy or the music is blaring.
  • It's better not to use it voice search in a noisy environment.

Well, sometimes the Navigator, like other programs, may refuse to function without any apparent reason. Wait, he will come to his senses and start working. Or follow the recommendations from the previous paragraph.

If Yandex Navigator does not work in Uber / Uber, video

What else can cause Yandex Navigator to malfunction?

If the current position is not displayed or changes suddenly, exit the application and enter again. Unfortunately, such failures are possible.

If the arrow indicating the direction disappears, or if you search for satellites for a long time and are periodically unable to maintain contact with them (especially on a long route) check the time settings, set the correct time zone.

For geolocation from satellites The time is also transmitted, and if it diverges greatly from the system time, errors are inevitable.

Occasionally, the program refuses to plot a route, citing the complete absence of a path between points - despite the fact that there is a road and you can drive along it. More often this happens abroad. Alas, the program is not omniscient, and accordingly, routes are not laid out everywhere.

Contact the developers, help improve useful software —

And sometimes there are reasons that in no way relate to the Navigator or satellites. There are several areas in the center of Moscow (in particular, near the Kremlin) where the application does not work. But this is not a mistake, but the foresight of the security services: special transmitters for the protection of strategic objects are interrupting satellite signal, giving out obviously incorrect data.

Conclusion

In the article, we looked at the main reasons that can lead to Yandex Navigator failures, whether on Android OS or another system.

Add your questions and comments about the program, we will discuss the features of its work with the whole world. Good luck on the road!!!

Many motorists are faced with a problem when the navigator does not see satellites. Several reasons can lead to such a situation - failure of the almanac, composition of automobile glass, failure software and failure of the receiving antenna. Almanac failure Most often, the navigator does not see satellites due to a failure of the navigation almanac. The fact is that the location of the device can be determined in three ways: hot, warm and cold start. If the device was recently turned off and then turned on again, a hot start is used. Typically it takes about fifteen seconds to find satellites. At the same time, information about the almanac and satellite orbits is stored in the device’s memory, which allows you to return to work in a short period of time. Also, the navigator does not need to request the ephemeris. Warm start means turning on the device in two to three minutes.

Why doesn’t the navigator see satellites, and how to fix the problem?

In this situation, you need to place the device in an open space and leave it in that position. After some time he will return to normal mode work.


Composition of automobile glass By the way, the navigator does not see satellites on those cars that use athermal glass. It has a special composition that shields signals.


The solution to the problem is to install the device near a special area for transmitting signals, located on athermal glass. Software failure In some cases, the navigator does not see satellites due to a software failure.
To fix the problem, you need to reflash the device. Branded car navigators- “Garmin”, “Navitel”, etc.
- can be updated on the manufacturer’s official website. For Chinese devices, software is more difficult to find, but still possible.

What to do if the navigator does not see satellites and what are the reasons

Attention

You can update the software yourself, but if this measure does not bring the expected result, then it is better to leave the “treatment” of the navigator to specialists. At self-updating firmware, you must carefully ensure that the software version matches the device assembly, otherwise the problem will not be solved.


The most difficult situation is when the navigator does not see a signal from the satellite due to failure or malfunction of the main components of the device, for example, the processor. This situation can only be solved by replacing these components, which is almost equivalent to purchasing a new navigator.

What to do if the navigator does not see satellites

Car owners often complain that the navigator does not see satellites. The reasons for such a deviation can be very diverse, for example, a violation of the device’s firmware or physical damage, resulting in partial failure of the device.

When using Navitel software, users often encounter firmware failures. You can reboot yourself. Main reasons Among the list of the most common reasons why the device may not see the satellite, the following factors are highlighted:

  • incorrect operation of the navigation almanac;
  • device firmware violations;
  • serious damage leading to failure of the gadget.

Problems in connecting the device to the satellite may also arise due to the presence of pronounced structural features of some vehicle windshields.

Yandex navigator does not work.

From the point of view of reliability of searching and tracking a signal, multi-channel receivers have advantages and operate more stably. The main responsibility for the situation in which the navigator does not pick up satellites lies with the signal receiver. It may include an external receiving antenna, which amplifies the signal from the satellite before entering the receiving path. In this case there is a malfunction technical support navigator. Possible technical issues, according to which the navigator stops seeing satellites:

  • failure of the GPS receiver circuit;
  • violation of the receiver's power supply circuits;
  • break of the communication cable with the remote receiving antenna;
  • remote antenna malfunction;
  • Incorrect location of the device in a shaded area of ​​satellite signals.

What to do to determine a specific technical reason, why Navitel does not see satellites.

Can't see satellites

If both the GPS module and the Internet connection are active, but the Yandex navigator does not work well and does not lead along the route, then you need to close the program and enter it again. It didn’t help - go to the settings and forcefully terminate it by clicking “Stop” (for Android; the algorithm is similar for iOS), and then go into the program again.

Important

If it doesn't help, reboot your phone. It didn’t help - delete the navigation program and download it again (but, as a rule, it rarely gets to this point; after all, Yandex Navigator is a fairly stable, non-glitchy program). But let’s say even this action didn’t help. Then you need to make the difficult decision and stop using this application on your current phone.


Well, they couldn't make friends. You have a choice of good analogues.

In this case, the device can be installed in such a way that it can receive the signal through the side windows or orient it towards a special transmission “window”, which many manufacturers provide for their athermal glass. Failure of the receiving antenna One of the most serious causes of loss of communication with satellites is the failure of the GPS antenna.
Navigators use two types of antennas - soldered to the board and external, connected to GPS navigator separately. An antenna soldered to the board is more difficult and more expensive to replace, but this type of antenna fails less often. Replacing an external antenna is much easier.

Your location

Any obstacle (car roof, dense foliage, multi-story buildings) reduces the quality of the GPS signal (and can block it completely). The phone needs to see the open sky! If you entered a tunnel ─ GPS signal will disappear, but Yandex.Navigator will continue to guide you along the route, although the accuracy of the location will deteriorate.

If the settings did not help If the settings listed above did not help, perform one of the procedures: a)

  1. Download Navigator. Minimizing an application by pressing the Back or Home button is not enough, you need to open everything running applications and dismiss the Navigator window.
  2. Restart Navigator.
  1. Turn off Wi-Fi.
  2. Launch Navigator.
  1. Turn on Airplane mode for 15-20 seconds, then turn it off.
  2. Launch Navigator.

d) Reboot your smartphone.

Ravid

A variety of problems can arise when using the Navitel navigation program. And one of the most common of them is that the navigator does not see satellites.

Of course, it cannot be said that such a situation occurs all the time. But in any case, the user must imagine what he can do on his own to fix problems, and what types of work can only be performed by specialists.

Firstly, as soon as such a problem appears, you should not immediately try to look for specialists to change the firmware and update navigation program. It is quite possible that some obstacles interfere with the navigator’s visibility of the satellites.

It could even be small canopies or too dense tree foliage. Therefore, as soon as a problematic situation arises, it is recommended to find an open place and wait while the device tries to establish communication with the satellites.

403 - access denied

Quite often, motorists are faced with a problem when the GPS navigator does not see or does not find satellites. This situation can be created for several reasons, among which the most common are the following:

  • navigation almanac failure;
  • device firmware failure;
  • technical features of windshields of some cars;
  • mechanical damage or failure of the receiving antenna.

To accurately determine the cause of the loss of communication with satellites, it is necessary to carry out appropriate diagnostics.

Let's look at each of the reasons in more detail. incorrect operation navigator. The navigator operates in three location modes: cold, warm and hot start. In cold start mode, the device does not have any information about its location.

Yandex navigator does not see satellites

If your path direction arrow disappears, or your phone spends a very long time searching for satellites and periodically loses them, especially if you are in long journey, then check the accuracy of the time on your phone, as well as the correct time zone. When determining your location, your phone constantly receives signals from satellites, including time information.

Time must be synchronized. Sometimes the Navigator displays a message that the route cannot be built because it cannot be passed. Mostly abroad. This is an imperfection of the program itself; the application is not aware of all paths.

Report such cases to the developers, so together we will create a program useful for all of us. Route guidance is not available in all locations. There are also curious reasons.

For example, the navigator does not work near the Kremlin and in some other places in the center of Moscow.

When the GPS navigator does not see or does not find satellites. This situation can be created for several reasons, among which the most common are the following:

  • navigation almanac failure;
  • device firmware failure;
  • technical features of windshields of some cars;
  • mechanical damage or failure of the receiving antenna.

To accurately determine the cause of the loss of communication with satellites, it is necessary to carry out appropriate diagnostics. Let us consider in more detail each of the reasons for the incorrect operation of the navigator.

The navigator does not see satellites due to an almanac failure

The navigator operates in three location modes: cold, warm and hot start.

In cold start mode, the device does not have any information about its location. Therefore, searching for satellites in this mode takes longest time and is about 10 minutes, or even more. In this mode, the navigation device must receive an almanac and orbital parameters that allow the position of the satellite to be determined with high accuracy. Next, the device receives ephemeris - parameters that allow you to more accurately determine the position of the satellite and tie it to the exact time.

In warm mode start GPS The navigator has a saved almanac in its memory, which was received the previous time it was turned on, as well as information about binding to the exact time. The duration of the search for satellites in this case is reduced to several minutes.

The hot start mode assumes that the device has been turned off recently and the information about the almanac and ephemeris has not become outdated. In this case, the search time is reduced to 10–25 seconds.

It should be noted that the lifespan of the almanac is 2-3 months, and the ephemeris is only a couple of hours. After this period has expired, data on the ephemeris and almanac must be updated. Therefore, turning off the device for a long time will cause the almanac to become outdated. Usually, after this, the navigator boots from a cold start and then operates in normal mode. But there are cases when, after a long shutdown, software failures occur that distort information and the navigator searches for a long time (several hours) and does not find its location. To bring such a device to normal operation, it is recommended to leave it for several hours in satellite search mode, ensuring good visibility of the sky. A few hours of searching should bring it back to normal operation.

The navigator does not pick up satellites due to a firmware failure

Quite often, devices stop functioning normally and lose contact with satellites due to a failure of the installed software. To restore normal work It is recommended to reflash it. Installing newer versions on the GPS navigator will provide it with more stable work, and will also allow the use of new functionality, which were previously limited old version firmware.

Quite often, the reason that the navigator does not see or does not find satellites is the athermal device installed on the car. Windshield. This glass has a special composition that can jam the signal. In this case, the device can be installed in such a way that it can receive the signal through the side windows or orient it towards a special transmission “window”, which many manufacturers provide for their athermal glass.

Failure of the receiving antenna

One of the most serious reasons for losing communication with satellites is the failure of the GPS antenna. Navigators use two types of antennas - soldered to the board and external, connected to the GPS navigator separately. An antenna soldered to the board is more difficult and more expensive to replace, but this type of antenna fails less often. Replacing an external antenna is much easier. Besides this there is a lot external antennas are interchangeable, which simplifies the diagnosis of the device and the search for the necessary spare parts.
