This integrity can be provided using a solution separation technique. Solution separation techniques involve maintaining a plurality of sub-solutions for the main navigation solution by a plurality of sub-filters 306-1 through 306-N (block 210 of Figure 2). A separate sub-solution is maintained for each set of N-1 satellites, where the main navigation solution incorporates measurements from all N satellites. Thus, each sub-solution incorporates measurements from a different combination of N-1 satellites. That is, sub-filter 306-n excludes measurements from satellite n. If a satellite has large errors, it will drive one or more of the sub-solutions away from the main navigation solution maintained by the main filter 304. More specifically, there are solution differences (also referred to herein as “separations”) between the main navigation solution of the main filter 304 and each sub-solution of each sub-filter 306.
