摘要： A method of communicating satellite tracking information among a network of global navigation satellite system receivers is described. The method includes determining at a first GNSS receiver which satellites in a constellation of satellites have been continuously tracked over a preceding selected time period, and for each such satellite determining its elevation with respect to the zenith. Only the elevation value for the lowest satellite in the set of satellites for which all satellites of higher elevation values have been continuously tracked over the selected time period is then transmitted to the second GNSS receiver. That receiver can then reconstruct the set of satellites which have been continuously tracked.

A first broadcast orbit message is utilized to nudge a broadcast orbit in use at the GNSS receiver to create a first nudged broadcast orbit for a GNSS satellite, the first nudged broadcast orbit being more precise than the broadcast orbit. A second broadcast orbit message is utilized to nudge the first nudged broadcast orbit in use at the GNSS receiver to create a double-nudged broadcast orbit for a GNSS satellite, the double-nudged broadcast orbit being more precise than the first nudged broadcast orbit. A third broadcast orbit message is utilized to maintain the double-nudged broadcast orbit, the third broadcast orbit message smaller than the second and the first broadcast orbit messages.
