Trimble navigation possesses a working GPS receiver capable of tracking Doppler frequency to .04 Hz with less than 1 sec averaging. This implies that #1 degree heading and attitude accuracies can easily be obtained with 3 antennas separated by less than 1 meter on a common ground plane. Innovative design permits common mode rejection of a major error source which for other known designs is a significant problem. Tremble is a commercial company with an excellent reputation in loran navigation receivers. The proposed heading and attitude sensor designed for the commercial market will definitely cost less than our commercial loran receivers ($2995)v
