Due to the deficiency of sliding Lagrange polynomial interpolation, the author proposes a new interpolation method, which considers the physical character of satellite movement in coordinate transformation and reasonable selection of interpolation function. Precision of the two methods is compared by a numerical example. The result shows that the new method is superior to the sliding Lagrange polynomial interpolation in interpolation and extrapolation, especially in extrapolation that is over short time spans.

针对由于遮挡等原因造成卫星信号中断后精密单点定位(precise point positioning,PPP)需要重新收敛的问题,提出了一种基于多接收机模糊度关联的动态PPP快速重新收敛方法。以远海地区精密定位为背景,充分利用了远海地区实践应用中经常在测量船的不同位置上架设多台接收机的基本特点,建立不同接收机的模糊度之间的关系,获取发生数据中断的接收机的先验模糊度,进而完成动态PPP的快速重新收敛。实验结果表明,附加基线长度约束的两个接收机单历元固定双差模糊度的成功率在99%以上;在单历元固定双差模糊度的情况下,无论数据中断多长时间,所提算法都可以单历元完成动态PPP的重新收敛,并且收敛后的定位精度同数据中断前的定位精度相同。

The precision assessment of the telemetry、track and command （TT＆C）equipment are important to ensure they can work normally. A new method is proposed for precision assessment of the space TT＆C equipment in this paper. In this method, anUnmanned Aerial Vehicle （UAV）equipedwith global positioning system （GPS） receiver acts as the target, well the positioning information of target is obtained by DGPS technology and the Kalman Filtering is used to reduce the effects of disturbance to enhance the positioning accuracy. The precisionof the space TT＆C equipment is obtained through thecomparison of the positioning data by DGPS and the observation by the space TT＆Col equipment. The UAV flightadjusting system is built based on this method in this paper, and the result of flying experiment shows that this system can provide the high-precision standard data, which have many advantages such as strong mobility and wide application scope.

A method of zero‐difference multi‐GNSS joint precise orbit determination of BeiDou satellites based on ambiguity fixed was present. The realization of ambiguity fixed was focused on. The real data was analyzed, and the results show that the three dimensional precision of GEO, IGSO and MEO can respectively reach 1.263m, 0.241m and 0.134m. The radial precision of the three types of satellites is averagely better than 10cm, and that of IGSO and MEO is mostly better than 5cm. After ambiguity fixed, the three dimensional precision of BDS is improved 21.8% averagely, and the tangential precision is improved most obviously, especially for GEO.
