摘要:
A method in a Global Navigation Satellite System (GNSS) receiver for double-nudged broadcast orbit drift correction. 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.
