摘　　要：机载精密单点定位可测量单个载体的位置和速度,这一模式能够满足大多数应用的需求。但在某些特殊应用场合,比如:远洋编队航行、舰载飞机着舰、空中加油、飞船交会对接等,要求解决两个运动目标之间高精度的相对定位问题。文中通过采用PPP模式和动基线测量两种模式对两个运动目标的相对定位进行比较与分析。Airborne precise point positioning serves for measuring the position and velocity of single carrier, complying with most application requirements. However, in some special applications, such as ocean-going fleet sailing, carrier aircraft, aerial refueling, the spacecraft rendezvous and docking,it requires to solve the problem of high-precision relative positioning between the two moving targets. Compatison and analysis are made on the relative positioning accuracy between PPP mode and moving baseline mode of two moving targets.
