Position output with imu fusion

Hi, I’m considering using Reach RS for rtk position, and output the NMEA format sentence of the rover to my computer.

I have some questions:

  1. If the gps positions which rover outputs has imu fusion to smooth the path?
  2. How the velocity information in GPRMC message generated, can it be used to calculate the orientation of rover, is it accurate enough? if not, is there a good method to get the orientation of the rover?


Anyone has some ideas?
