How to get the active number of satellites ?

[HamzaCetin0]

Hi,
I would like to obtain the number of active satellites used in the position solution of the base station, not just the satellites that are being tracked. I'm aware that the NAV-SAT message includes a field called numSvs, but this only represents the total number of tracked satellites, not necessarily the ones used in the position computation. I have highlighted the specific parameter I'm referring to in the attached figure. Could you please help me?

Hi @HamzaCetin0

The parameter you're after is commonly referred to as SIP (Satellites in Position), as opposed to SIV (Satellites in View). The NAV-SAT numSvs attribute is equivalent to SIV.

If you're using UBX data, SIP is available from the NAV-PVT numSV attribute.

If you're using NMEA data, SIP is available from the GNGGA numSV attribute.
