+Pete_the_Geek Posted September 28, 2021 Share Posted September 28, 2021 I have an interesting issue on my 66sr. I have been doing a lot of learning/playing with RINEX observations and believe I have have come across an issue where RINEX appears to receive multi GNSS Multi-Band RINEX data initially but after somewhere around 6 hours, GLONASS satellites (G1 and G2) begin to reduce until they are no longer received and similarly for Galileo (E1 and E5) but after 10 hours approximately but these times vary. The handheld never recovers so only GPS L1 and L5 is received from that point on. L5 also begins to reduce but is still received sporadically. Before you ask, I have done several tests all with the same result, with my main test site being in a very clear view of the sky with no obstructions 10 degrees above horizontal. Also it is very near (12km) from a UK base station that continues to receive multi frequency GPS, Galileo, GLONASS and BeiDou signals then the 66sr does not. Has anyone else had this experience? I have raised a support case and am running another test occasionally viewing which satellites the device's satellites status shows it can see, comparing this to my phone at the same time so I can further determine if it is a RINEX issue or a device issue.
