ABSTRACT:
A location of a target is generated by, at each of a plurality of reference sensors, receiving signals from a plurality of positioning system satellites. A set of error measurements are generated by generating, for each of the reference sensors, one or more error measurements based on a reference location of the reference sensor and information derived from the signals received at the reference sensors from the plurality of position system satellites. Single differenced velocity corrections are also generated. At a central processing node, a meta-correction surface is generated from the set of error measurements. The meta-correction surface is then transmitted to a non-reference sensor. At the non-reference sensor, signals are received from a plurality of the positioning system satellites. The meta-correction surface and the signals received from the plurality of position system satellites are used to generate the location of the target.
