目前正在考虑使用全球定位系统(GPS)接收机在导弹试验和鉴定(T＆E)应用中提供时间、空间、定位信息(TSPI)以及脱靶量(MDI)数据。特别是,正在评价GPS接收机在“响尾蛇”导弹遥测系统(AN/DKT-80)中作为一种传感器的有效性。初步的测试表明,当使用双差分误差修正技术时,由GPS接收机提供的定位信息比雷达跟踪系统好得多。这种方法需要在遥测站附近放置一个GPS参考接收机。已开发的软件比较来自空中的GPS接收机与参考GPS接收机的数据并实时显示TSPI结果。该软件还可由来自安装了GPS接收机的两个不同空中目标(导弹和靶机)的信息计算出脱靶量。为了证明这个构思的正确性,将一种流行的(COST)、商用的C/A码GPS接收机综合进AN/DKT-80“响尾蛇”遥测系统(TM)。一个MQM-107靶机安装相同的GPS接收机,同样的GPS接收机安装于地面作为参考接收机。在靶机上开发一个简单的遥测系统专门遥测GPS数据。修改的AN/DKT-80遥测系统加入惯性测量单元(IMU)。开发的事后处理软件综合了IMU信息与GPS数据。即使GPS数据瞬时丢失,仍能产生精确定位信息。证明这个构思的导弹发射试验安排在1999年春天进行。
GPS receivers are currently under consideration for providing time, space, positioning information (TSPI) and miss distance (MDI) data in missile test and qualification (T & E) applications. In particular, the effectiveness of the GPS receiver as a sensor in the Rattlesnake missile telemetry system (AN / DKT-80) is being evaluated. Preliminary tests show that when using a double-difference error correction technique, the positioning information provided by the GPS receiver is much better than the radar tracking system. This method requires placing a GPS reference receiver near the telemetry station. Developed software compares data from GPS receivers in the air and reference GPS receivers and displays TSPI results in real time. The software also calculates miss distance by using information from two different aerial targets (missiles and target aircraft) that have a GPS receiver installed. To prove the validity of this idea, a popular (COST), commercial C / A code GPS receiver was integrated into the AN / DKT-80 Rattlesnake telemetry system (TM). The same GPS receiver is mounted on an MQM-107 target and the same GPS receiver is mounted on the ground as a reference receiver. Develop a simple telemetry system on the target aircraft to telemetry GPS data. The modified AN / DKT-80 telemetry system joins the inertial measurement unit (IMU). Developed post-processing software combines IMU information with GPS data. Even if GPS data is lost instantaneously, accurate positioning information can still be generated. The missile launch test to prove this concept was scheduled to take place in the spring of 1999.
