Abstract: A method includes obtaining an initial survey of multiple receivers located on a dynamic platform. The method also includes obtaining sensor readings from the multiple receivers. The method further includes validating, using a differential calculator, the initial survey by (i) selecting a reference receiver and a target receiver from among the multiple receivers and (ii) calculating, based on the sensor readings and baselines between the reference receiver and one or more remaining receivers, a platform attitude, platform thermal expansion state, and survey error values corresponding to the target receiver. The method also includes, starting from a validated survey, adding a new receiver to the initial survey by (i) determining a baseline between the reference receiver and the new receiver and (ii) associating the baseline to a coordinate frame of the initial survey.
