Gps does not find android satellites. Android GPS calibration, acceleration of satellite acquisition after a cold start, increasing GPS accuracy essentially to the possible limit of hardware


Built-in GPS is one of the standard features modern smartphones, thanks to which mobile users can use various navigation applications such as Google Maps and receive exact coordinates, for example, of your own location, localize this or that object on the map, plot travel routes, etc.

However, different Android devices are equipped with different types of GPS sensors, which in turn differ in their technical parameters.

Accordingly, depending on the quality of operation of such sensors, the GPS quality-signal that each is capable of providing separate model smartphone.

Plus, the quality of the GPS signal is also seriously affected by other important factors, in particular system settings the device, the software used, the quality of the connection and even the firmware version of the device.

In this article we have collected some useful recommendations, how to improve GPS quality in Android smartphones and tablets . So

First, you need to make sure that your Android device has GPS function activated. To do this, go to “ Settings" device (we use this Lenovo P770), open the section " My location"(Location Access) and there we enable (check the boxes) the options " Access my location data" (Access to my location) and " By GPS satellites"(GPS Satellites).

GPS Calibration
Often the reason for a decrease in the quality of a GPS signal can be a poorly calibrated compass in a smartphone, as a result of which the device incorrectly calculates coordinates, constantly producing incorrect data. You can set up a compass in Android OS using special utility, of which there are many on the Internet. GPS Essentials, For example. After installing this application, you just need to launch it and press the button Calibrate. Next, the program independently optimizes the GPS settings in your smartphone.

If after completing the calibration the GPS quality remains unsatisfactory, then you can use the diagnostic function to try to find out the cause of the malfunction and figure out whether it is related to the shortcomings of the installed software, or the problem lies in the hardware. GPS Essentials launches additional test, based on the results of which the program will display a list of possible reasons for poor GPS performance; the process also determines, among other things, the number of satellites from which the smartphone receives a high-quality signal.

If it was not possible to improve the quality of GPS (or find out the reason for its poor performance) using the GPS Essentials utility (and this also happens), then last resort You can reboot the GPS module of your Android smartphone. The fact is that sometimes the device gets stuck on satellites that are out of range and stops receiving signals from available satellites. Full reboot The GPS module resets all current settings and resumes the original ones. In our Lenovo P770, we rebooted the GPS module using the utility GPS Status&Toolbox, which was also downloaded from Google Play.

After installing and launching the application, you need to go to the A-GPS status manager menu ( Manager A-GPS State) and just press the button Reset Data . The program will reset all existing GPS module settings and restore the factory settings. This optimization method can also be used for preventive purposes, so to speak, when the quality of the GPS in the smartphone deteriorates again.

Reflashing the device
Another radical way to improve the quality of GPS on an Android smartphone or tablet involves flashing the device. However, only advanced users can use it effectively. Inexperienced users, on the contrary, may not only fail to correct the situation with GPS, but will most likely damage the device. However, with a competent approach to the matter, flashing can eliminate shortcomings in GPS operation and significantly improve the accuracy and quality GPS signal, and also speed up the search for satellites. Of course, o backup Don't forget the data.

On modern devices mobile communications GPS and GLONASS sensors are installed. On devices with operating system Android system, in particular, this makes it possible to always determine your location and draw up routes using maps on your phone, without using paper counterparts. This is especially true for navigators installed in the car. But what to do if GPS does not function on Android? First of all, we will find out the reasons, and then we will try to correct the situation.

Reasons for GPS not working on Android devices

The simplest and most easily remedied reason that GPS does not work is an inactive navigation module. If your smartphone has not been set to operate the navigation module by default, you need to do it manually. Beginners may not figure out this reason until they open the settings. You need to sweep down and in the menu that opens, next to the clock and notification shortcuts, switch “Geolocation” to active mode.

After activation, navigators in applications will work as standard. In many applications with a navigator, the user is notified if the module is not active. Applications for creating routes on phone maps automatically redirect the user to the menu after activating the module before starting work.

If you have activated the module and turned everything on, but the GPS does not respond to your actions, you just need to wait up to 15 minutes for the data to load, they do not work in lightning-fast mode. Satellite visibility and download speed depend on many factors, ranging from weather to stability mobile signal from the tower. After the first download, the data will be installed and will be opened quickly in the future.

You also need time to recognize a new place when you arrive with your device in another region or country. The smartphone first determines its location and then operates quickly in this environment.

Other reasons why GPS may not work when first started:

  • You are trying to start the navigator while driving - stop the car and allow the device to boot in a calm and stable position;
  • You are in a place where there is no connection - GPS does not turn on indoors, unlike the Internet;
  • You launch the navigator in an area with natural interference for the satellite - mountains, vegetation, buildings.

After you have found one of the listed reasons and fixed the problem, the navigator on Android will work. If this does not happen - you have problems with the device - contact the service center to set up the software.

If your GPS was working and then stopped, this indicates internal breakdown apparatus. Before sending it to the service center, try to fix it yourself, namely, reset the settings to the factory level, perhaps you have been tricky with the settings and confused the device.

Using the Chartcross ltd program you can do a GPS Test to check the satellite coverage area in your area. When the module is working properly on the device and there is no interference with the signal, you will see on the application screen a map of the sky above you with dots that indicate the location of the nearest satellites.

How to make GPS settings on Android

There is no need to make any special settings, everything works automatically. If you want to customize something, you can change the way the signal is detected:

  • The signal will be highly accurate if you use all reception points - the GPS module on the phone, Internet Wi-Fi and satellite;
  • Energy saving is a mode when using telephone networks and Internet Wi-Fi;
  • GPS only - satellites will work.

You need to go to the settings in the “Geodata” section, where you need to check the box. The navigator will work using a special program. There are applications for smartphones, for example, Maps.me. Its functionality also includes convenient cards, which can be used offline, its use is free.

Some owners Android smartphones They often encounter the problem that the GPS module cannot pick up satellites or takes a very long time to pick up satellites. GPS navigation. This mainly happens with phones that were brought from China or purchased from Chinese sites such as Aliexpress and they were not fully customized to Russian conditions.

The first thing we should do is go to the settings of the smartphone and go to the tab My location. Turn on GPS and check the boxes opposite, By GPS satellites And By network coordinates. If you have more Extra options settings, such as EPO parameters then put a tick in front of the item, go down to the bottom and press the button download.

Next we need to go to engineering menu. In the engineering menu we go Location - Location Based Service - EPO and bet against the parameters Enable EPO And Auto Download checkboxes, if you don’t have these parameters, then they are by default and hidden from your eyes.

We return to Location and go to the section YGPS and on the tab INFORMATION press the buttons sequentially fuii - warm - hot - cold And AGPS restart This is done to reset the old almanac, and in order for us to record a new almanac, we go to the tab NMEALOG and press Start to record a new almanac.


Go to the tab SATELLITES and we see that we have several red satellites on the radar. After some time, from 5 to 30 minutes, some of the satellites should turn green, and signal strength scales will appear below, this means that your phone has established a connection with these satellites. You need to catch satellites on the street and preferably away from houses, since indoors the signal is extinguished and it is almost impossible to catch them.



If after a while the connection with the satellites has not been established, then the problem lies deeper and in order to fix it, you will need root rights on your smartphone. How to get root We read the rights in the article “Opening root rights in Android”. Rights root we need to edit the file GPS.conf. So using file manager which works with root(I used Root Browser) go to the root directory of the phone and look for the file at the following address system - etc - gps.conf. By using text editor open the file gps.conf and look at what’s there, this file stores the addresses of the satellite servers, but for some reason it turned out to be empty for me. If yours is also empty or there are some addresses of other countries, then we change the contents of the file to the settings we need, save, close and reboot our smartphone.

Next, you will need to repeat all the manipulations with the engineering menu and on the tab SATELLITES Let's see how our smartphone catches satellites. All the above actions helped me and the phone immediately began connecting with 6-10 satellites.

That's all today modern smartphones equipped with built-in GPS module, which shows your location. You can use your smartphone as a navigator while playing sports or traveling by car, and also use it to receive current news or weather information in your city. Now let's figure out how to check the operation of GPS on Android, that is, whether the location module works on your device or not.

There are 2 options to resolve this issue, simple to use the application, and a little more difficult to use standard features your smartphone (engineering menu).

Checking and setting up GPS using the app

Based on all the applications that we tried, the simplest and most effective turned out to be. This program can quickly help you find all the satellites in your region, pre-configure them and, possibly, use other functions.

Features of the GPS Test program for Android

  • Shows information about visible satellites;
  • Shows active satellites currently in use;
  • Gives accurate data geopositioning;
  • Shows exact coordinates;
  • Gives information about the time zone at the location;
  • Indicates the position of satellites in the sky;
  • Can serve as an electronic compass;
  • Provides a variety of data, ranging from time and date to altitude;
  • Gives information about sunrise and sunset times in the place where the device is located.

How to check the status of your GPS navigator using GPS Test

We open the application, and if we see in the left top corner inscription " 3D Fix“This means that the navigator works correctly and performs all its functions without the slightest problem. Shows " No Fix"? Unfortunately, there is a problem with the device and its smooth operation is impossible.

Constant switching between the above modes may also be due to bad conditions to receive a GPS signal. This is caused not only by being in a closed room, even inappropriate weather, such as rain or strong wind.

Shows " off"? Everything is simpler here. The receiver is simply turned off. To enable it, we perform an easy procedure: open “Settings”, go to the “Location” item. A new menu called "Location Services" opens. There are three modes in total:

  1. "By network coordinates"
  2. "GPS satellites"
  3. Supporting Data.

To most accurately determine a location, for example, in a car, we recommend activating all items at once. Of the networks, Wi-Fi works best, of course, but if conditions do not allow this (being on the street, etc., as is usually the case), use mobile Internet.

Using this program you can learn a lot useful information about your phone and its additional features.

Setting up and adjusting GPS through the engineering menu

This method will help you check the quality of the established standards that indicate how well the GPS on your phone works.

  1. To do this, you need to go to the engineering menu. Enter the code (where we usually write the subscriber number) *#*#3646633#*#*;
  2. Next you need to find the YGPS item (or something similar);
  3. As a result, a map should appear with many yellow dots on it. They may not appear immediately.

Just these points and talk about the number of satellites that were found. If you record the time from the start of scanning until all found satellites are fully loaded, the quality of the installed GPS will become known. Later, this data can be compared with other devices, for example, by taking it from a friend.

Video instruction

Poor performance of GPS satellites indoors

But do not forget that GPS may have poor signal reception when you are standing indoors (especially in a high-rise building) or close to electrical appliances. So it is better to use the location function in an open area (street) or, as a last resort, near a window.

It's worth remembering that GPS is better Do not leave it on all the time, use it only when necessary. This will save battery charge two or even three times longer. Using widgets, you can turn GPS on or off on your desktop.

Yandex Navigator is the main navigation development of Yandex, the leading Russian-language search engine. The application is absolutely free and can be downloaded to any smartphone running various operating systems, including iPhone (iOs 8+) and Android (3.0+). Today, this is one of the most popular navigation programs among smartphone users, and, of course, many people encounter certain features and problems in using this software. Let's look at the most popular of them and try to give solutions.

So, for some reason you have Yandex navigator does not work.

Of course, the word “doesn’t work” can mean dozens of situations - from the inability to turn on the application to some difficulties in geolocation in certain regions. We will try to cover all the points in more detail, including those related to poor knowledge of the telephone structure. If you are not a beginner, you can read diagonally :)

In this article we will talk exclusively about solving problems that may arise when using Yandex Navigator. Read instructions and “life hacks” for using it in our other articles in the “Navigation” section.

Yandex Navigator does not work from the very beginning

You have the program installed, but it doesn’t open, it produces various errors, and “crashes” immediately after turning it on. It is quite possible that it was initially installed incorrectly on your smartphone.

Today, almost 100% of smartphones can work with this application, so the possibility that your phone is “weak”, has insufficient memory, etc. is practically excluded. The only exception is if the navigator freezes or works with huge delays. IN in this case we can really say that the smartphone “doesn’t work.” As a rule, this happens with devices with RAM less than 512 MB (256 MB, for example). It's really not enough.

But let's return to the first case. You just need to reinstall the program on your phone. In the smartphone settings, delete the application, go again to the place where you downloaded it (for example, for Android smartphones this is Google Market), and download it, and then install it again. If the problem was incorrect installation, then it will disappear.

You turn on the program, but it does not detect your location. Accordingly, it is impossible to either plot a route or perform any navigation-related actions. Make sure you have GPS turned on on your phone. After that, go to the window or go outside, and wait until your phone determines the satellites, and from them - your location.

Yandex Navigator is a program designed for installation on smartphones. This means that it works according to A-GPS system. This means that your location can be determined not only by satellites, but also by towers cellular communications. Those. in city conditions, you actually don’t have to turn on the GPS module, but this will cause some inconvenience when working with the navigator interface (for example, there will be a huge green circle around your location on the map, which will interfere with reading the information), and the positioning accuracy will decrease slightly.

Why Yandex Navigator does not work without the Internet

In fact, Yandex Navigator works without the Internet, but for this you need to do some preliminary actions. First of all, download maps directly to your phone, which the program will guide you through in the absence of the Internet. How to do it? Enter the application, select the “Menu” item, then “Download maps”, enter your city, and if there is a map for it, download it. It must be said that Yandex Navigator covers the space of Russia, Ukraine and many other countries very well, so there should not be any problems with finding your region.

When downloading maps, use Wi-Fi, as their size can be very large.

However, you still won’t be completely free from the Internet with this program, so in a sense, Yandex navigator really doesn’t work without the Internet. You will have maps on your phone, but to build a route or search the area you will still need network connection. The way out of this situation can be called planning a route in advance, and then being truly free from the Internet while moving along this route. In any case, you will significantly reduce the amount of Internet traffic and increase the speed of your navigator.

Of course, in the absence of the Internet, Yandex Navigator will not be able to convey to you other information that may be useful. For example, about traffic jams. By the way, if the situation with traffic jams on the road is not shown, you need to click on the traffic light icon in the corner of the navigator (in given time yours is grey). After that, it will light up in one of the colors, depending on the severity of traffic jams in your city. The degree of traffic congestion is displayed with a number from 0 to 10.

The navigator does not lead along the route

Again, you first need to check if you have geodata transfer enabled. After that, check your Internet connection, including its speed (use the built-in browser on your phone, load a couple of sites). 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. 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.

Voice search doesn't work

Here the problem could be either a broken microphone on your phone or a lack of internet connection. Also possible reason There may be noise in the surrounding area - for example, on a busy street or with loud music. Make sure that voice commands were heard in relative silence. In addition, Yandex Navigator, like any program, can sometimes become stubborn and not work for no reason. He will get over it, so be patient and follow the steps in the last paragraph if necessary.

Other reasons why Yandex Navigator does not work well

If your location sometimes disappears or changes, then simply re-login to Yandex Navigator. This happens sometimes, this is how the current program works.

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. This is caused by security measures, or more precisely, by the work of a special transmitter that replaces the signals of real satellites.

So, we found out the main reasons why Yandex navigator does not work on Android and other popular operating systems. Any questions and comments are welcome, we will discuss this together useful application. And, of course, follow and read our other materials in the “Navigation” section.
