Abstract
A GNSS cooperative receiver system that can be utilized when one or more GNSS receivers is in a compromised position where it cannot receive direct signals from a sufficient number of GNSS satellites. This may in the interior of an office building or multi-dwelling unit, which may be in the vicinity of other tall buildings. The receivers determine their relative positions from one of various ranging techniques, and then with this relative position information, pseudoranges, and correlation values from the various GNSS receivers, the best GNSS solution can be determined for the group of cooperative receivers. This could include two or more receivers in a group. There also related techniques for one receiver to be a designated, remote anchor for other GNSS receivers that need such assistance.
