Google Map GPS Cell Phone Tracker allows you to track Android, iOS, Windows Phone, and Java ME cellphones using Google Maps. It has two parts, a server and phone clients. You have a choice of two servers, using asp.net and SQL server or PHP and MySQL. The server software allows you to view cellphone locations in realtime using Google Maps and store routes and view them later. The client applications send their locations to the website periodically. All four applications work properly in the background and are written natively on each platform.
GPX Viewer is a simple program to visualize a GPX file. It uses libchamplain and cairo for the plot. It can show multiple GPX files, show waypoints and multiple tracks per GPX file, highlight a selected track, show a speed vs. time graph, and show distance, duration, average, moving average, max speed, moving time, and GPS points. It supports zooming, smoothing of the speed graph, and highlighting points in a speed graph on a map.
LocDemo demonstrates the functionality of libwlocate. After startup, it evaluates the current geographic position of the user and displays it within a map. This solution offers geographic localization that works without the use of GPS and without submitting tracking or position data to commercial providers of such services.
O2OO reads sensor data from a car into a sqlite database and generates graphs of the data so you can analyze the behavior of the car. It can also retrieve the location from a GPS module and store it in the same database, then can create a Google Maps KML-file, coloring the route line with a color depending on a sensor reading.
fastgps is a fully functional GPS software receiver which demonstrates all the steps performed in a GNSS navigation receiver. This receiver includes: an FFT acquisition; code and carrier tracking; pseudorange measurements; navigation data decoding; and position, velocity, and time estimation functions. The software receiver is also capable of using external aiding data from the International GNSS Service (IGS) as well as applying WAAS differential ionosphere corrections.
