  • Differential phase measurement scheme for a multiplexing GPS attitude receiver
    Patent number: 5929805
    Abstract: A method for reducing master antenna tracking errors in a multiplexing GPS receiver resulting in a differential phase measurement scheme which is insensitive to the master antenna tracking loop errors is disclosed. The master antenna tracking loop error at a given update K is subtracted from a phase measurement associated with a slave antenna signal at update K. The method comprises the determination of interpolation coefficients by which the master antenna tracking loop errors are weighted in order to minimize each of the slave antenna differential measurements.
