Satellite Navigation Data Mining (SENDAI)

SENDAI is a software for analysis of GNSS performance and comparisons of GNSS constellations. It provides details statistics of orbit and clock errors, failure rates, anomaly reports and analysis of navigation parameters in summarized tables, various charts or even maps. Data can be aggregated and filtered in different manners by flexible user interface. For example, users can select a time period of their interest: day, month, year, or longer. Satellite-related results can be grouped by satellite generation, individual satellite, or constellation. It provides excellent overview and constellation comparisons for long-term evolution analysis.

The tool analyses navigation data of all currently active GNSS (namely GPS, Glonass, Galileo, Beidou, QZSS and IRNSS) satellites. The system is currently used exclusively by ESA and Iguassu will need ESA permission to make it available to third parties.
