I've got a Matrice 600 Pro with the D-RTK module that keeps throwing an internal IMU error when flying. The groundstation and airframe are all level and speced according to the manual. I have green on both gound and air units, and the controller indicates 17+ satalites and ready to fly. Immediately in the air, the 600 starts drift and then I get an internal IMU error on the controller.
For troubleshooting, I landed the craft and powered down. Disconnected the power and CAN bus connections to airframe D-RTK. Then started everything up just without the D-RTK connected. The 600 had no issues during initilization and flight, in fact it was more posistion accurate with the 3 GPS modules than with the RTK running. The only thing that bothers me is all the documentation shows the 600 as using only 1 A3 series GPS module, I am running with all three that came with the 600 Pro + the D-RTK. I am not sure if this is the root cause and for right now can do the jobs needed using the 3 GPS modules, but I will need to use the D-RTK in the near future.
Any help would be greatly appreciated.
