Claim:
1. A device for determining a position and an orientation of a first rigid body with respect to a second rigid body, the device comprising: a plurality of radio frequency (RF) transmitters, wherein the plurality of RF transmitters transmits a plurality of RF signals in a first frequency range, and wherein each one of the plurality of RF transmitters is coupled to the first rigid body; at least one RF antenna coupled to the second rigid body, wherein the second rigid body is moveably coupled to the first rigid body, and wherein the at least one RF antenna receives the plurality of RF signals; a first GNSS antenna coupled to the second rigid body, wherein the first GNSS antenna receives a plurality of GNSS satellite signals in a GNSS satellite signal frequency range, wherein the GNSS satellite signal frequency range does not overlap the first frequency range; a second GNSS antenna coupled to the second rigid body, wherein the second GNSS antenna receives the plurality of GNSS satellite signals in the GNSS satellite signal frequency range; and a receiver circuit, wherein the receiver circuit calculates the position and the orientation of the first rigid body with respect to the second rigid body in response to the receiver circuit receiving:
