  • FGI-GSRx software receiver | National Land Survey of Finland
    The FGI-GSRx software receiver has been extensively used as a research platform for the last one decade in different national and international Research and Development (R&D) projects to develop, test and validate novel receiver processing algorithms for robust, resilient and precise Position, Navigation and Timing (PNT). At present, the FGI-GSRx can process GNSS signals from multiple constellations, including GPS, Galileo, BeiDou, GLONASS, and NavIC. The software receiver is intended to process raw Intermediate Frequency (IF) signals in post-processing. The processing chain of the software receiver consists of GNSS signal acquisition, code and carrier tracking, decoding the navigation message, pseudorange estimation, and Position, Velocity, and Timing (PVT) estimation. The software architecture is built in such a way that any new algorithm can be developed and tested at any stage in the receiver processing chain without requiring significant changes to the original codes.

  • Help me test gps-share
    See also https://zee-nix.blogspot.com/2017/05/introducing-gps-share.html and https://github.com/zeenix/gps-share
    gps-share is a utility to share your GPS device on local network. It has two goals:

    Share your GPS device on the local network so that all machines in your home or office can make use of it.
    Enable support for standalone (i-e not part of a cellular modem) GPS devices in Geoclue. Since Geoclue has been able to make use of network NMEA sources since 2015, gps-share works out of the box with Geoclue.

    The latter means that it is a replacement for GPSD and Gypsy. While "why not GPSD?" has already been documented, Gypsy has been unmaintained for many years now. I did not feel like reviving a dead project and I really wanted to code in Rust language so I decided to create gps-share.

  • Galileo Satellite Metadata | European GNSS Service Centre
    The Galileo satellites metadata are information about the satellite properties which need to be known in order to properly implement advanced processing algorithms for precise orbit determination or Precise Point Positioning (PPP). These include physical characteristics such as mass, area or reflectivity, the attitude law and antenna parameters such as phase center offsets and variations. More information about PPP and GNSS data processing can be found in [3], [4] or [2]. For Galileo SIS details, please refer to [1].

  • LEA-6T GPS breakout board with Precision Timing - CSG Shop
    The uBlox LEA-6T supports precision GPS timing for demanding positioning applications such as basestations. It features a time mode function whereby the GPS receiver assumes a stationary 3D position, whether programmed manually or determined by an initial self-survey. Stationary operation enables GPS timing with only one visible satellite and eliminates timing errors which otherwise result in positioning errors. An accuracy of up to 15 ns is achievable by using the quantization error information to compensate the granularity of the time pulse. A built-in time mark and counter unit provide precise time measurement of external event inputs
