Abstract
In the paper, a differential GPS correction method is proposed for a sounding rocket experiment. DGPS schemes are known to be capable of removing common-mode errors between GPS receivers that are in vicinity. However, for a sounding rocket that could reach into the ionosphere, the standard differential correction method including local-area differential correction and wide-area differential correction may not be directly applicable due to the de-correlation between the on-board receiver and the receiver on ground as well as the limitation of the thin-shell model in modeling the ionospheric delay. In this paper, a differential correction scheme is proposed and applied to a sounding rocket program. The proposed scheme relies on the establishment of altitude-dependent ionospheric and tropospheric correction terms for GPS raw measurements. Together with rocket kinematics, a filtering solution of the rocket trajectory is obtained. In the paper, the data collection process is delineated and the post-processing results of a sounding rocket experiment are reported.
