Velocity and Acceleration of Doppler Calculation for Carrier Based on GPS Broadcast Ephemeris
摘要
Abstract
Doppler frequency shift is the most important observation data of GPS receiver,which has the characteris-tics of high precision,real-time and no influence on the cycle slip. A real-time acquisition method of carrier velocity and acceleration is developed around Doppler observations. Because of the timeliness and accuracy of the velocity and acceleration of the satellite is the key to restrict the velocity and acceleration of the carrier based on the Doppler method,this paper deducts the real-time velocity and acceleration calculation formula based on broadcast ephemeris. The carrier velocity and acceleration model are established based on the GPS Doppler with broadcast ephemeris. Static experiment and dynamic experiment are carried out and the experimental results show that the carrier velocity and acceleration algorithm based on GPS Doppler with broadcast ephemeris can meet the precision requirement for vehicle navigation.关键词
