摘要
Abstract
In order to realize GPS navigation in low SNR environment,such as indoor and city environments,the basic principle of signal acquisition in navigation receiver is introduced.Several common acquisition methods of satellite signal such as coherent integration,non-coherent integration,differential correlation integration and circular correlation integration are analyzed.Coherent integration and differential correlation integration are chosen finally to design the high sensitivity GPS chip,and the results of simulation demonstrate that the normal acquisition for satellite signal can be successfully implemented by using this chip in such 15 dBHz CNR environment.关键词
