Abstract
A ground-based system to reduce the effect of interference, comprising a plurality of reference receivers, wherein the reference receivers are spaced a distance apart such that a single source of interference is unable to substantially interfere with a subset of the plurality of reference receivers, wherein the subset of the plurality of reference receivers includes at least two reference receivers; and a processing module communicatively coupled to the plurality of reference receivers and configured to receive data from each of the plurality of reference receivers, wherein the processing module is further configured to perform differential calculations on the data to calculate measurement corrections and estimated errors.
