Hello.
If I mount simpleRTK2Blite on a simpleRTK2B board and use it with a fixed base, in what form can I get heading?
Currently, I connect a Bluetooth module to the RX1/TX1 of the SimpleRTK2B rover(MR kit) and retrieve NMEA GGA and VTG messages for the AgriBus-NAVI. It works perfectly, but it’s unfortunate that the direction on the screen is reversed when the tractor is backed up.

In a dual receiver implementation the relative displacement is reported via UBX-NAV-RELPOSNED,baseline length, orientation and attitude drop out with high-school math/geometry, and you’d need to convert those into vehicle heading based on a understanding of the physical placement on the vehicle, ie left-right vs front-back.
