We write the program which used for fighting errors in absolute positioning. we also write the program which used for linear combinating in absolute positioning. from analyzing for the measurement of outer, we can conclude that we can use m estimation to estimate parameter in gps absolute positioning. lt has application value. using it, we can obstain the stable positioning result and remove the outer. in this paper, we calculate the data which from the baseline space of the gps calibration space. we also draw some conclusion using broadcast ephemeredes and smoothing pseudoranges. the positionging precision is in 1 - 2 meter
編制了gps絕對定位中抗差估計程序和應用線性組合進行單點定位的程序。通過對粗差量級的分析，得出在gps觀測量存在粗差時， m估計是有其應用價值的，它使定位結果較為穩定，減弱和剔除了粗差的影響。應用線性組合程序對gps綜合檢定場數據基線網點進行計算，得出用廣播星歷和平滑后的偽距可以給出較好的結果，點位精度在1 ? 2米。The budget used for planning the development activity for an iteration, based on rough order of magnitude estimates
