Abstract
A radio frequency component receives and digitizes a first plurality of L1 Global Navigation Satellite System (GNSS) signals and a second plurality of L2C GNSS signals from a plurality of GNSS satellites. A software defined GNSS receiver operating on a processor of a cellular telephone separate from the radio frequency component derives carrier phase measurements from the first plurality of L1 GNSS signals and the second plurality of L2C GNSS signals during an epoch. A wireless message from a communication device located at a base location is received conveying pseudorange and carrier measurements derived from the first plurality of L1 GNSS signals from said plurality of GNSS satellites during the epoch. The cellular telephone determines a distance from the base location to said first location.
