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.
phpMyGPX is a Web application based on PHP, MySQL, and OpenLayers to manage photos and GPX files with a browser, on your local machine or online, to share your tracks and images. GPX is an XML file format containing track points and routes collected by GPS receivers, and is very popular with navigation, geocaching, and OpenStreetMap.
The gps_installer is a GTK+ application used to integrate custom Ada library projects into the Gnat Programming Studio (GPS). The installer is designed to be as simple as possible. It takes the directory where the source files are located and the list of files to install. The installer tries to figure out where to move the files and how to process them. No specific actions need to be specified.
MerakoGPS is a set of software for Merako-series boards. It is meant for GPS receiver development. MerakoGPS runs on a flexible Merako-series hardware board which uses a CycloneIII FPGA to accomplish the correlator function, and NiosII or ARM to do GPS signal acquisition, tracking, navigation message decoding, and PVT computing.
