高动态地基伪卫星接收机载波跟踪技术
Research of Carrier Tracking Technology for High Dynamic Terrestrial Pseudolite Receiver
摘要
Abstract
Considering the characteristics of terrestrial pseudolite receiver in terms of CNR( Carrier to Noise Ratio) and frequency excitation when receiving signal,the analysis of the carrier tracking performance of third order PLL is made,it might suffer from loss of lock due to the limited CNR and the high⁃order frequency excitation of received signal. To improve the carrier tracking performance of pseudolite receiver under a high dynamic condition,an INS/pseudolite deeply coupled carrier tracking approach is proposed which can estimate and compensate the frequency offset of received signal based on the high⁃frequency positioning and velocity information provid⁃ed by the INS and the pseudolite position information.A simulation experiment shows that this deeply coupled algorithm behaves more stable and accurate carrier tracking performance when the receiver moving in a rectilinear motion at an acceleration of no more than 10 g attempts to receive signals from pseudolites nearby.关键词
