摘要
自1980年第一台商品GPS信号接收机问世以来,GPS信号接收机不断更新换代,日新月异。综析了GPS信号接收机的新近发展,主要表现在下述方面:用软件无线电技术实现GPS信号接收机的软件化;用蓝牙技术实现GPS数据的无线传输;用通用无线分组业务(GPRS)扩展RTK移动站的作用距离;用SAASM技术直接捕获和跟踪P码;用内置增强跟踪技术研制成GPS/WAAS/EGNOS集成接收机。
This paper focuses on the following recent development of GPS receivers： to make software GPS receivers using the software radio technique ; to realize wireless transmission of GPS data using the Bluetooth technique ; to increase action ranges of RTK rover using the General Packer Radio Service; to acquire and track directly P（Y） code using the Selective Availability Anti-Spoofing Module; to manufacture GPS/WASS/EGNOS integrated receivers using the built-in enhance tracking technologies.
