ABSTRACT:
A GNSS enabled mobile device receives GNSS assistance data in a determined format from a central processing station communicatively coupled to a wide area reference network (WARN). The WARN comprises a first plurality of GNSS tracking stations from which usable signals are received by the central processing station, and a second plurality of GNSS tracking stations from which unusable or no signals are received by the central processing station. The central processing station generates the GNSS assistance data using a complete set of GNSS reference feeds of the WARN. The complete set of GNSS reference feeds comprises actual GNSS reference feeds from the first plurality of GNSS tracking stations and virtual GNSS reference feeds derived for the second plurality of GNSS tracking stations from processed actual GNSS reference feeds. The generated GNSS assistance data is reformatted into a determined format and is communicated to the GNSS enabled mobile device, accordingly.
