GNSS REGIONAL CORRECTION DATA DECODING
First Claim
Patent Images
1. A method of preparing regional GNSS corrections from a correction message, the method comprising:
- receiving a correction message, the correction message;
having at least one network message containing network elements relating to stations of a network of stations located within a region, andhaving at least one cluster message with each cluster message containing cluster elements relating to a respective subset of the stations;
extracting network elements from the at least one network message;
extracting cluster elements from the at least one cluster message; and
preparing from the network elements and the cluster elements correction data for use with rover observations to determine a position of a rover within the region.

Abstract
A correction message for regional GNSS data includes data from several stations in a network. The correction message has at least one cluster message. The cluster message contains cluster elements relating to a subset of GNSS stations.
