Summary:提出了一种集成设计导航定位与数传通信的差分导航通信系统,以满足无人机对机载轻量化高精度导航定位的需求.该差分导航通信系统由地面站和机载设备组成：地面站完成差分卫导修正量生成与播发;机载设备接收地面站播发的差分卫导修正量,并结合本地卫导观测量实现高精度的实时动态定位.系统试验结果表明,该差分导航通信系统在50km范围内具备亚米级精度的导航能力.
Bibliography:To satisfy the requirements of light weight and high-precision navigation positioning of unmanned aerial vehicles（ UAVs）,an integrated system supporting satellite navigation and communication functions is suggested. The integrated system is composed of the ground station and the airborne equipment. The ground station is designed to generate and broadcast the differential Global Navigation Satellite System （ GNSS） corrections. And the airborne equipment is designed to receive the GNSS corrections and achieve the Real Time Kinematic（ RTK） positioning by combining local GNSS observations and GNSS corrections. The ex-periment results show that the integrated system has the capacity to provide sub-meter level navigation po-sitioning within a 50-kilometer radius.
