A system, for enhancing location estimates by movable rovers that use receivers for processing ranging signals from orbiting satellites, including a fixed base station that serves as a ranging signal source for the rovers' receivers. The base station may also determine and transmit the azimuthal angles of the respective rovers. The rovers use this information, along with a calculated or transmitted ranges to the base station to calculate the ranging system times at the locations of the rovers. Further, the rovers may use the information along with signals from satellites in view to determine position.
