I am part of a team making a Radio Controlled Plane and we plan on using RTK GPS receivers for the altitude measurements of the plane. We plan to have one receiver on the plane and another at our base station (laptop) to correct any error from the receiver on the plane. I am wondering if anybody has used an RTK GPS for specifically RC Aircraft as opposed to a UAV or Drone, because I am not trying to incorporate an autopilot system as that defeats the purpose of our RC Plane. I am open for any suggestions.
