Horizonal Accuracy gpsh_acc -1 with wireless telemetry #2670

Open jondave opened 3 years ago

Issue details

I have a Pixhawk 4 when connected with a USB cable directly to my computer mission planner gives a value of horizontal accuracy / gpsh_acc (usually around 0.9 to 1.5 outside) but when connected via wireless telemetry the horizontal accuracy is always -1. In Mavlink inspector gpsh_acc is always 0 when connected with wireless telemetry but is -1 in the Quick view panel. The correct gpsh_acc values are recorded in the data logs when connected either via USB or wirelessly.

The same problem exists for the Holybro Pixhawk 4 GPS modules and for the Holybro H-RTK F9P Rover Lite GPS modules.

update the FW on your telem radios. and also check you have mavlink 2 enabled on that port
