摘要： The present invention is a method and apparatus for establishing a common datum georeferenced position of the phase centers of the antennas used by a system. The system includes a GPS receiver and an auxiliary transmitter. An auxiliary antenna of the auxiliary transmitter is co-located with a GPS antenna of the GPS receiver. The auxiliary antenna is at a known spatial relationship with the GPS antenna. An auxiliary position of the auxiliary antenna is determined based on the known spatial relationship.
