AbstractI. The present writer has been trying for the past two years to get reasonably easy expressions for the (t – t) correction and the scale factor in the Lambert NO.2 Projection. He succeeded in obtaining a formula for (t – t) in terms of eastings and northings, but, like the author of the articles on “Grid Bearings and Distances on the Conical Orthomorphic Projection” which were published recently in this Review, he came to the conclusion that any such formula is too unwieldy for ordinary use. He then tried to get an expression for (t – t) in terms of latitude and longitude, and has now obtained one by purely empirical methods which seems to work in practice. No proof of this formula is offered, or is available at present, as this is a matter which the writer is content to leave to others with greater mathematical interests and attainments than he possesses. 相似文献

3 动态 GPS定位自从利用 GPS载波相位观测的机载动态定位于 1 985年第一次得到证实之后 ,可靠的 GPS解支持航空摄影测量、遥感活动和地球物理测量的能力显著改进了。这些改进来源于若干因素的综合 :第一 ,运动 GPS接收机可以跟踪 8颗或更多颗卫星 ;第二 ,可以得到精密星历供后处理之用 ;第三 ,提出了一些算法 ,它们能以少量的相位和伪距观测量在运动中初置相位偏差。这些因素综合起来 ,产生了精确到厘米级的动态定位能力。这就是动态 GPS定位技术。它可以把距离延伸到约 1 0 0 km。采用 KARS( Kine-matic And Rapid Static)程序… 相似文献
