About GPS Display
This is a very lightweight app that displays the following GPS-related information:
(1) The current GPS longitude, latitude and accuracy, as well as a longiture/latitude plot of the last 1000 positions.
(2) The last network-derived position, if you have an internet connection. Note that no history is kept for network-derived data - only the most recent longitude and latitude are shown.
(3) The altitude and speed of the last 60 minutes (or 1000 measurements). The speed range is fixed to 0 to 40 km/s, while the altitude plot moves with the current altitude.
(4) The current bearing, as well as the measurements of the last 30 seconds as cloud plot.
(5) An azimuth/elevation plot with all satellites in view and their current SNR. Satellites in blue are used to calculate the GPS position. The blue ring indicates the total SNR. Higher values mean better reception.
The app requests GPS updates while in foreground, and keeps requesting updates for 30 seconds after it disappears from the screen. This keeps the GPS receiver running when you briefly hide the app, or switch to another GPS app (e.g. maps).
The displayed and plotted values are the raw (unfiltered) values obtained through the Android Location API.
The app is neither interactive nor configurable. You cannot zoom in or out, or change the way the information is displayed. This app only requires GPS access, and does not contain any ads.
