1. A method to determine a position of a master antenna relative to a position of at least one other antenna, the method comprising:
- generating phase carrier measurements for a carrier frequency and at least three antennae including the master antenna and the other antennae;
generating phase integer sets based on the phase carrier measurements;
verifying the phase integers of the generated phase integer sets based on a summation of estimated baselines and a fixed baseline between two of the other antennae; and
calculating the position between of the master antenna and relative to the position of at least one other antenna based on the verified phase integer set and the fixed baseline between two of the other antennae.
