Abstract

See full text

A receiver system for determining coordinates of a location can include two GNSS receiver antennas positioned in fixed relation to each other and separated by a short baseline. Signals received from the two receiver antennas can be processed to define a “virtual” antenna located at the midpoint between the two receiver antennas. For instance, a location can be determined for each receiver antenna using GNSS-based techniques, and the locations of the two antennas can be used to determine a location of the virtual antenna. As another example, GNSS observables from the two antennas can be combined to provide a set of “virtual” observables for the virtual antenna, and GNSS-based techniques can be applied to the virtual observables to determine a location of the virtual antenna.
