Abstract: | Airborne users of GPS may benefit from differential (relative) navigation to the extent that the errors in their measurements of pseudorange and/or delta range to each satellite are correlated with observation errors for the same satellite signals received at a reference site. This paper describes some results of an experiment to characterize the measurement errors of one airborne GPS user equipment. The results suggest that pseudorange errors are dominated by slowly varying systematic processes that are likely to be highly correlated from user to user, whereas delta-range errors appear to be zero-mean processes that are dominated by user generated noises, especially clock jitter and tracking errors. |
