| 摘 要： | Sierra 9803型飞行校验系统是一款采用DGPS进行定位的飞行校验系统,在国内仅有一套该型号的飞行校验系统.该飞行校验系统投入使用已达25年之久,其差分系统已经严重老化,关键部件破损严重,无法正常执行飞行校验任务.为此彻底研究了9803型校验系统,并对其GPS差分系统进行升级改造,对差分信号进行解码分析并重新编码,对机载差分信号接收机及校验系统相关模块进行软件升级,同时更新地面差分系统及其监控系统,最终对改造后的校验系统进行飞行验证,彻底解决问题,使其能够重新正常执行飞行校验任务.

| Abstract: | Sierra Model 9803 flight inspection system(FIS) is to use DGPS positioning.There is only one set in the domestic.It has been used for over 25 years,and the GPS differential sub'system has serious aging,key components have been severely damaged,unable to perform the normal flight inspection task.A thorough study of the Model 9803 FIS is maken,and the GPS differential sub'system is upgraded,the differential signal is decoded and recoded,the airborne differential signal receiver and related module are upgraded.Then the ground differential sub'system and its monitoring system are upgraded.The reconstructed system is checked through flight verification.The problem is solved completely,so that it can perform the normal flight inspection task. |
