Long range GNSS ephemeris data transfer method and apparatus using the same

Abstract

Disclosed are methods of transferring satellite ephemeris data for a first GNSS satellite from a pseudolite to a GNSS receiver. Also disclosed are pseudolites and GNSS receivers implementing the same. A first satellite global positioning signal transmitted by the first GNSS satellite is received at the pseudolite. The pseudolite transmits a pseudolite global positioning signal containing the satellite ephemeris data for the first GNSS satellite. The GNSS receiver receives the pseudolite global positioning signal and retrieves from the pseudolite signal the satellite ephemeris data.
