Abstract
Official abstract text for this publication.
A navigation system includes first receiver receiving satellite signals, second receiver receiving differential correction data from ground receivers, and processing device coupled to receivers. Processing device determines correction data for satellite signals based on differential correction; determines position solution based on satellite signals and corresponding differential correction data; determines first position sub-solutions based on satellite signals from all but one satellite (different for each first position sub-solution) and corresponding differential correction data; calculates first separations as function of first differences between position solution and first position sub-solutions; determines second position sub-solutions for mobile object based on satellite signals and corresponding differential correction data from all but one block of ground receivers (different for each second position sub-solution); calculates second separations as function of second differences between position solution and second position sub-solutions; detects error in position solution when one of first separations or second separations exceed corresponding separation limit.
First claim
Opening claim text (preview).
What is claimed is: 1. A navigation system for a mobile object, comprising: a first receiver configured for reception of satellite signals from a plurality of satellites; a second receiver configured for reception of differential correction data from a plurality of blocks of ground receivers; at least one processing device communicatively coupled to the first receiver and the second receiver; wherein the at least one processing device is configured to determine correction da…
