ARCHITECTURES FOR HIGH INTEGRITY MULTI-CONSTELLATION SOLUTION SEPARATION

摘要

A method comprises receiving a plurality of signals from a plurality of space-based satellites, wherein the plurality of space-based satellites comprises at least one space-based satellite from each of a plurality of Navigation Satellite System (NSS) constellations. The method also comprises determining, in a first domain, a first plurality of sub-solutions based on a respective sub-set of the plurality of signals, each respective sub-set in the first domain chosen according to a characteristic defining the first domain; and determining, in a second domain, a second plurality of sub-solutions based on a respective sub-set of the plurality of signals, each respective sub-set in the second domain chosen according to a characteristic defining the second domain. The method further comprises determining if an error is present in the navigation system based on the first plurality of sub-solutions and on the second plurality of sub-solutions.

1. A method of integrity monitoring for errors in a navigation system, the method comprising:
receiving a plurality of signals, each signal transmitted from a respective one of a plurality of space-based satellites, wherein the plurality of space-based satellites comprises at least one space-based satellite from each of a plurality of Navigation Satellite System (NSS) constellations; determining, in a first domain, a first plurality of sub-solutions for the navigation system, wherein each sub-solution in the first plurality of sub-solutions is determined based on a respective sub-set of the plurality of signals, each respective sub-set in the first domain chosen according to a characteristic defining the first domain; determining, in a second domain, a second plurality of sub-solutions for the navigation system, wherein each sub-solution in the second plurality of sub-solutions is determined based on a respective sub-set of the plurality of signals, each respective sub-set in the second domain chosen according to a characteristic defining the second domain; and determining if an error is present in the navigation system based, at least in part, on the first plurality of sub-solutions in the first domain and on the second plurality of sub-solutions in the second domain.
