Multi-Constellation Long-term GNSS Assessment

Project aims to develop a tool capable of continuous long-term comparison of performance of GNSS constellations and augmentation systems. Software generates PDF reports that provide easily accessible information on the long-term progress of these systems and their evolution in time. Reports provide comparison of orbit & clock errors, accuracy and integrity performance and signal analysis per each monitored station in form of summarized tables and graphs.


  • Long-term analysis of large sets of GNSS data
  • Provides performance comparison of GNSS and augmentation systems
  • Support for GPS, GLONASS, Galileo, EGNOS, Beidou, QZSS
  • Monitoring MGEX stations around the world
  • Implementation of ARAIM algorithms
  • Analysis of accuracy, integrity, availability per station
  • Orbit & clock errors comparison
  • Information summarized in PDF reports – daily, monthly, yearly
