Abstract
The present invention is a method for dynamically determining a blended navigation solution for a mobile platform (ex.—aircraft) via a receiver implemented on-board the platform. In the method disclosed herein, the receiver concurrently utilizes data from satellite signals obtained from a plurality of independent satellite constellations in calculating its (the receiver's) navigation solution (ex.—Position, Velocity, Time (PVT) solution), thereby overcoming weaknesses inherent in currently available systems and methods, which rely on only a single satellite constellation.
