Abstract

The Global Positioning System (GPS) was developed in 1973 in order to overcome the limitations of previous navigation methods and became fully operational in 1995 Nowadays the GPS provides convenience for people and becomes an irreplaceable part of life It’s desired to develop a naviga-tion tool for high-dynamic vehicles by using GPS techniques Existing commercial GPS receiver cannot normally operate in these vehicles There are large change of acceleration due to the moving of high-dynamic vehicles that causing huge Doppler frequency shift Such a huge Doppler frequen-cy shift will impose stress on the tracking loop of commercial receiver to lose of lock Thus the key of research is to develop techniques to compensate for the effect by Doppler frequency shift This thesis will discuss the problem against the high-dynamic environment and develop a high-dynamic GPS receiver which can overcome more than 10g acceleration changing and prevent losing lock of satellites A series of experiments are conducted to verify the performance of receiver in static dy-namic and actual rocket launch scenarios The research results in this thesis are helpful to verify rocket trajectory and develop high-dynamic receivers
