Abstract:
A method for determination of the locations of, and line biases for, two or more spaced apart GPS signal antennas in a kinematic or static environment, the method comprising the steps of:receiving GPS carrier phase signals from at least two GPS signal sources at each of at least two GPS signal antennas and associated GPS signal receivers;measuring double difference phase signal observations for the carrier phase signals received at the at least two GPS receivers from at least two GPS signal sources and determining fixed value double difference phase integer ambiguities;computing a single difference range for each of the at least two GPS signal sources and determining single difference phase measurements for the at least two GPS signal sources; andsubtracting the computed single difference range from the single difference phase measurement, identifying the integer part of this difference with a single difference phase integer ambiguity, and identifying the fractional part of this difference with a line bias for a signal processing channel associated with each of the at least two GPS receivers.
