GPS Monitor - Description
About the app
GPS Monitor helps you to check navigation satellites explored by your device and location information they provide. The application displays the objects of the following global navigation satellite systems (GNSS): GPS, GLONASS, Beidou, Galileo and other systems (QZSS, IRNSS). In addition, you can get your current latitude, longitude, altitude, heading and speed data. The application does not require an Internet connection, so you can determine the location even in airplane mode.
Monitoring start and stop
Measurements of satellite navigation system parameters are performed by background service. It can be started or stopped by clicking on the button in the top bar of the application. An icon appears in the notification area when background service is on.
User interface
The application contains four sections in the tabs Overview, Locator, Satellites, and Location. In addition to tapping a tab, you can switch between them by swiping left and right.
Overview tab
This tab contains information about the current state of navigation system: longitude, latitude, altitude, speed and bearing, number of visible satellites and number of satellites used in fix.
Locator tab
Locator is a constantly updated map of navigation satellites. The map rotates like a compass: the red arrow points north, the white arrow points south. Satellite icons are plotted in a polar coordinate system according to azimuth and elevation. Satellites used in location fix are highlighted. You can filter satellites by system type and usage.
Satellites tab
The tab contains a list of navigation satellites and their basic parameters: type, identifier, azimuth, elevation, signal-to-noise ratio and signal frequency. The list can be filtered by system type and usage. It is possible to sort the list by signal-to-noise ratio and by navigation system.
Location tab
This section contains a world map and the current location marker. Besides, there are current longitude, latitude and altitude values.
