In one of the articles we looked at the question of how to make a TV remote control out of a smartphone.

It is difficult to find a smartphone that is not equipped with a GPS module. Even the most budget gadgets have this useful navigation tool installed. It doesn’t matter what model your smartphone is if you need to get directions or find out the location in an unfamiliar place. To turn on GPS on your smartphone, you don’t need any special knowledge - you press the right button and everything works. But not everyone knows how to configure GPS on Android so that the smartphone’s battery does not overload.

We will tell you about the main stages of setting up GPS, and also recommend several Android applications with which you can check the operation of the GPS module.

GPS does not start automatically on your smartphone. To enable and configure it, you need to dig a little into the settings. In each version of Android, the activation path looks a little different. We will look at the main steps to enable and configure GPS in a smartphone running Android 6.0 Marshmallow.

Stage 1: Turning on

To turn on GPS, slide the notification shade down and click on the bar that displays the time, date, and battery charge. You need to click on the gear icon, after which you will be taken to Settings. In addition, you can access the settings through the corresponding button in the general menu. Find the Personal Data section and click on the Location button. At the top of the screen there will be a switch that activates GPS.

Stage 2: Setup

By default, the location of the smartphone is determined from all sources. GPS, Wi-Fi, Bluetooth and mobile networks data are used to accurately determine the location with an accuracy of 10-15 meters. This function ensures high reliability of geolocation, however, please note that this mode puts a lot of strain on the smartphone’s battery. Therefore, in the settings you can choose one of two economical modes:

• By network coordinates
• By GPS satellites

The first mode uses only Wi-Fi, Bluetooth and mobile network data. It is necessary that the smartphone is connected to the Internet via Wi-Fi, or the user needs to start Bluetooth mode. Without a network connection, the location of the smartphone is determined by the base station signal.

If there is no access to the Internet, and the nearest radio tower is several tens of kilometers away, then you should enable geolocation using GPS satellites.

Once the GPS on your smartphone is turned on and configured, you can safely install the navigator application for Android. The most convenient and functional navigator you can choose is .

To check how GPS works on your smartphone, you can download a special application from the Google Play store. We'll look at three programs available for free download. For them to work properly, you need to go outside.

OS version: Android 4.0 or later
Download

The application allows you to check the quality of GPS signal reception, supporting GPS, GLONASS, GALILEO, SBAS, Beidou and QZSS satellites geolocation systems.

Complete GPS test information is displayed on six main screens:

1. GPS signal (SNR). A chart that shows the signal strength for each satellite, as well as the accuracy and status of the GNSS network.
2. Positions of satellites in the sky.
3. User's current location. Displayed with coordinates on the world map. The position of the sun and the transition curve between day and night are noted. The screen can be used as a navigator.
4. Screen compass
5. Current speed, course and altitude
6. Current GPS reading time and local time in the current time zone, as well as sunrise and sunset data for a given location.

The disadvantage is the lack of Russian language. On the other hand, the application interface is easy to learn.

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 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 due to incorrect installation, 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 using the A-GPS system. This means that your location can be determined not only by satellites, but also by cell towers. 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 take some preliminary steps. 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 this? 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'll have maps on your phone, but you'll still need a network connection to plot a route or search the area. The way out of this situation is to plan a route in advance, and then be 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 your traffic jam situation is not shown, you need to click on the traffic light icon in the corner of your navigator (it’s gray at the moment). 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. Another possible cause could be a noisy environment - for example, on a busy street or with loud music playing. Make sure that voice commands are given 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, that's how the current program works.

If your direction arrow disappears, or your phone spends a long time searching for satellites and periodically loses them, especially if you are on a 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 stating 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 have 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 useful application together. And, of course, follow and read our other materials in the “Navigation” section.

Many people want to know how to improve GPS reception on Android devices if navigation applications are experiencing problems. Most often, a weak signal is a result of hardware problems, but sometimes the problem can be fixed by adjusting system settings.

Navigator diagnostics

Data-lazy-type="image" data-src="http://androidkak.ru/wp-content/uploads/2017/07/GPS-nastroyka1-300x178.png" alt="GPS navigation" width="300" height="178"> !} In order to determine why the signal has become weaker, you need to install the application GPS Essentials. In the main menu of the program, in the Satellites tab, you can view the list of available satellites. If the screen is empty, then there are only 2 options:

• there are objects nearby that create interference;
• The navigation system does not work correctly due to hardware problems.

Sometimes the gadget shows that it is connected to a satellite, even if it is no longer in range. To connect the device to an available device, you need to install the application GPS Status & Toolbox or something similar. Next you need to do the following:

1. Click on the application work area. Then - to the wrench icon that appears.
2. Select Manage A-GPS state.
3. Click Reset.
4. After the reset is complete, return to the previous menu and select Download.

This will update the navigation system data. If this helps fix the error, then the next time there is a failure, repeat the procedure.

Acceleration of coordinate calculations

Data-lazy-type="image" data-src="http://androidkak.ru/wp-content/uploads/2017/09/Gps1.jpg" alt="a-gps" width="170">!} GPS determines the position of an object based on data received from satellites. There are many factors that influence the reception of signals, and therefore the speed and accuracy of determining coordinates. The main thing is information about the location of the satellites at the current moment. In the absence of this data, the time for calculating coordinates can increase to several tens of minutes.
Technology was invented to solve the problem A-GPS. It transmits satellite location data from the server to the smartphone. Since the domestic market is filled with devices made in China, the addresses listed there are not local.

To increase the speed of location determination, you need to change the server information in the gps.conf system file. This can be done manually, editing each line of code. But it is much faster to download a ready-made file with the server addresses of the country in which the user is located.

To solve this problem, the following conditions are necessary:

• Internet access;
• having root access;
• a file manager installed on the smartphone (for example Root Explorer);
• gps.conf file with server addresses;
• application for testing results.

The presence of navigation modules on smartphones with Android OS allows you to use numerous navigation applications - they are used to plot walking, cycling and car routes, as well as to track your own location. Therefore, it is customary to give special preference to the presence of GPS/GLONASS chips. GPS not working on Android? It doesn’t matter - first we’ll try to figure out the reasons, and then we’ll talk about troubleshooting.

Why GPS may not work on Android

If GPS does not work on your Android smartphone, then the problem may be extremely trivial - the navigation module is disabled. This is often encountered by novice users who do not fully understand the design of Android smartphones. In order to enable navigation, you need to slide down the top curtain, behind which numerous shortcuts, clocks and notifications are hidden, and find the “Geodata” item here - it should become active (green, bluish, etc.).

Now we can launch the navigation program and start using it. By the way, many navigation applications can notify users that geodata reception is disabled. This is exactly what the popular Navitel application does - it will issue an appropriate warning and even send the user to the navigation enable menu. After this, you can start plotting your route.

Have you enabled geolocation in your device settings, installed the necessary applications, but have not been able to achieve any results? It is quite possible that the whole point is your impatience. If this was the first launch of the GPS/GLONASS module, try waiting 10-15 minutes - during this time the electronics will process information about satellites visible in the area. All subsequent launches will occur much faster.

You need to do the same thing if you arrive with the navigator turned off to another region, for example, from Rostov to Novosibirsk - you need to give the navigator time so that it can recognize its own location (by analogy with the initial “cold” start).

Here are some more reasons for GPS not working:

• You are trying to perform a “cold” start on the move (in a car) - stop and let the navigator think. Some chips are quite slow, so they need time and rest;
• You are indoors - GPS does not work inside buildings (not to be confused with calculating location using cell towers and Wi-Fi zones);
• You are in an unfavorable reception area - the sky is obscured by trees, nearby rocks or tall buildings. In this case, you need to get out under a more open area of ​​the sky.

If the navigation still does not work, try contacting the service center.

GPS stopped working on Android, although it worked before? This behavior indicates the presence of some internal damage.. If you are too lazy to go to a service center, try doing a factory reset.

To test your satellite reception, use the GPS Test app from Chartcross Limited. If the geolocation function is turned on, the GPS chip is working, and you are outdoors, you will see dots indicating satellites on a schematic sky map.

How to set up GPS on Android

Some users are wondering how to set up GPS on Android? No special settings are needed here, but you can play around with the detection method:

• High accuracy - in this mode, location is determined using all wireless modules (GPS/GLONASS, telephone module, Wi-Fi);
• Energy saving - Wi-FI and mobile networks are used;
• GPS only – only satellites are used.

The detection method is selected in the “Settings – Geodata” menu. To further work with navigation you will need suitable software. You can choose the free Maps.ME application with offline maps or the paid Navitel application.

Does GPS work poorly on Android? Set the mode to “GPS Only” or “High Accuracy”, and then try to test the navigation again - these are the most accurate modes.

Today, all modern smartphones are equipped with a built-in GPS module that shows your location. You can use your smartphone as a navigator while playing sports or driving, and you can also use it to get up-to-date 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 using the application, and a little more complicated using the standard capabilities of 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 the 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 poor conditions for receiving a GPS signal. This is caused not only by being indoors; even unsuitable weather conditions, such as rain or strong wind, can affect it.

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 find out a lot of useful information about your phone and its additional capabilities.

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.

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 near 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 is worth remembering that it is better not to leave GPS 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.
