| 摘 要： | 介绍了GPS单点定位技术的发展及其定位原理;描述了ADS40数码航空摄影试验情况;比较了差分GPS定位与精密单点定位所获取摄站坐标的差值,分析了差值产生的原因;并比较分析了利用两种摄站坐标进行光束法区域网平差的精度。试验结果表明,在有5点控制的情况下,两者加密精度基本一致,无控的情况下,两者的加密精度相差较大,但均能满足1:10000以下中小比例尺航测成图要求。

| Abstract: | Firstly,the principle of GPS precise point positioning(PPP) was introduced.Secondly,the experimental result of ADS40 in aerial photogrammetry was described.Thirdly,the GPS antenna coordinates acquired by DGPS method and PPP method were compared and analyzed.Finally,the accuracy of bundle block adjustment using different positioning method was researched.Experimental results showed that using five ground control points,the accuracy of GPS-supported aerotriangulation with GPS data by PPP method is closed to t... |
