Abstract
An example pointing system includes a sensor that measures change in angular position, a first GNSS antenna, and a second GNSS antenna mounted to a rigid body that is removable from the pointing system after calibration of the sensor. The GNSS antennas have a fixed, known baseline. The pointing system includes at least one GNSS receiver with first and second RF inputs respectively coupled to the GNSS antennas. The at least one GNSS receiver includes respective paths to process GNSS signals received from the first and second RF inputs. The pointing system includes at least one processor, communicatively coupled to the sensor and receiver, configured to: determine initial attitude of the pointing system based on the processed GNSS signals; calibrate the sensor using the determined initial attitude; determine a pointing solution for the pointing system based on measurements from the calibrated sensor without GNSS signals from second GNSS antenna.
