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.
GPSBook is a tool to be used with your GPS receiver (GPSr). It manages traces, routes, and waypoints in gpx or Loc format. This tool can be used for geocaching, sports training, tracking, travel, and many outdoor activities. GPSBook can display map in 2D and 3D using google maps, satellite, terrain, earth or openStreetMap and openCycleMap.
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.
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.
OpenGGD (Open GPS Gateway and Database) aims to be a solution for centralizing vehicle fleet GPS information, acting as an interface among different GPS devices or their control programs and different GIS programs. OpenGGD is mainly a GPS database infrastructure. It is neither a program for controlling GPS devices nor a mapping tool.
