METHODS AND APPARATUS FOR ESTIMATING POSITION IN A SATELLITE DIFFERENTIAL NAVIGATION SYSTEM

摘要

Disclosed are methods and apparatuses for estimating the floating ambiguities associated with the measurement of the carrier signals of a plurality of global positioning satellites, such that the floating ambiguities are preferably consist for a plurality of different time moments. In one aspect of the invention, a real-time iterative matrix refactorization process is provided which reduces processor load and retains history of the measurements.
