Abstract
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.
