BNC is configurated to save rinex navigation files (GPS and GLONASS separated)on a directory with an interval of 15min. When I start a stream (RTCM3.1 on TLSE1 station for example), BNC produce rinex navigation files, but some of them are empty or other one contains only GPS information. But when I scan the stream, I found 1019 and 1020 RTCM messages each 30s. Could you please explain us this behavior? does BNC take into account only one time the ephemeris of a PRN and wait a new generation of ephemeris to save it ? Thank you for your answer. Best regards Gregory" task closed normal BNC fixed
