Hello everyone, I’m having some issues with RTK.
I’m using:
- H-RTK mosaic-H dual antenna;
- Hardware: CUBEPILOT_CUBEORANGEPLUS,
- Carrier board: Kore carrier board;
- Base RTK: H-RTK F9P GNSS Series (IST8310 Compass);
- Autopilot: PX4 V1.15.4,
When I run QGC and switch on the drone, my GNSS receivers start counting satellites (around 24 with status: 3D Lock). After the survey-in of the base, the antennas receive RTK corrections from the base, but the number of satellites drops immediately (to about 12 with status: 3D RTK GPS Lock (Fixed)). How is this possible?
Furthermore, when I move the drone by hand to another location, I lose the RTK fix, and it becomes very difficult to obtain it again. I have a very basic setup with only the dual antenna connected to the carrier board and an antenna for telemetry. There are no rotors or structures; I am testing only the receivers.
Here is a log for reference: https://review.px4.io/plot_app?log=93ce411a-13c6-4d0b-b2c8-c30bf5961f18
I tried different baud rates, from 115200 to 921600, but nothing has changed.
Could you help me?
