摘　　要：详细介绍了卫星干扰源定位系统中星历校正的测量原理。干扰源定位系统就是对非合作目标进行定位和定轨,测量体制较为特殊。国外相关系统定位精度在几十至百公里量级,星历校正精度在几公里至几十公里量级。针对目前干扰源定位系统精度较差的问题,给出了采用精密定轨方法对两颗同步卫星进行星历校正。通过仿真数据进行处理,最终定轨精度达到十米量级。该方法的研究及工程化使得我国自行研制的卫星干扰源定位系统具有自主测定轨能力。The t principle of ephemeris calibration is introduced in details for satellite interference source location system. It is usually designed for location and orbit determination of non-cooperative target, thus the measuring mechanism is rather special. The accuracy of the foreign-related positioning system is in the level of one hundred to tens kilometers, and the accuracy of ephemeris correction is in the level of tens to one kilometers. Aiming at the low positioning accuracy for the current interference source localization system, the paper gives a precise orbit determination method with two synchronous satellites for ephemeris calibration. By the simulated data, the final orbit determination accuracy reaches to ten meters. The results indicate that the interference source localization system of our country has the capacity of independent orbit determination.
