Hi, what is the vv_error parameter? (L26-DR GNSS Protocol Specification)

Stone.Chen-Q · February 4, 2021, 12:40pm

Hi，
vv_error represents the difference between the speed calculated by the GNSS Kalman algorithm and the DR Kalman algorithm inside the module.

Best regards

Hi, but we also have the parameter speed_error, what is the difference between speed_error and vv_error?

Stone.Chen-Q · February 9, 2021, 2:32am

Hi,
Sorry for the error in the previous explanation.
In fact, speed_error is the horizontal speed, and Vv_error is the vertical speed.

Best regards

ok, do you have any doc to learn what are the vertical and horizontal speeds and what are they used for? thanks

No.
Under normal circumstances, the debug information will not be used.
Please ignore it.
