Full textAbstract
This is the paper style requirement for the Chinese Control Conference. The writers of papers should and must provide normalized electronic documents in order for readers to search and read papers conveniently. An INS-aided acquisition approach is proposed in order to solve the difficulty of GNSS signal acquisition in the high dynamic environment. It utilizes information of Doppler and pseudorange, that from INS and Ephemeris to reduce the range of carrier wave frequency, the length of the C/A code is shorten. So that the acquisition time can be reduced and the acquisition performance of high dynamic receiver can be improved. Performance analysis of INS aided GNSS signal acquisition based on motion dependence of INS, the equations of performance between INS and GNSS signal acquisition are reduced. Simulation shows that INS composed of 100(°)/h bias drift gyros and 1mg bias drift accelerometers aided can obviously reduce average acquisition time and increase Sensitivity.
