| 摘 要： | 根据Trimble 4000SST的随机数据处理软件和自行编写的DDKIN动态测量数据处理软件,处理了车载DGPS一秒数据率的动态载波相位测量数据,结果表明,两者的三维位置较差在4mm以内。用卡尔曼滤波数据处理方法,获得了汽车的三维运行速度。此外,还取得了外部事件写入4000SST数据流的模拟试验结果。

| Abstract: | By means of Trimvec Plus software and DDKIN software written by three authors,the carborne DGPS data of one second update from carrier phase measurements are processed. The resuls indicate that the maximal difference between Trimvec Plus and DDKIN software processing is equal to four millimeters. The three--dimension velocities of the car carrier were acquired to make use of Kalman filter processing. In addition we executed the analogous test measurements for writing external events into 4000SST data flow to use 1PPS from a cesium clock on 26 Feb. 1993. |
