Application of Global Position System Real Time Kinematic to Photocontrol Point Measurement in Large Scale Aerial Survey and Analysis of the Precision

摘要

With the widely application of large scale aerophotogrammetry, the traditional measurement methods already can't satisfy the efficiency requirements of Photocontrol Point Measurement. There are some obvious advantages in GPS RTK, so it's applied to Photocontrol Point Measurement. This article takes Jiaozuo with an aerial survey of 1:2000 for example, and introduces the operation of GPS RTK, analysis the problems in the procedure of operation, and also offers solution. As a result, the article provides a good reference to the application of Photocontrol Point Measurement. It analysis the measurement accuracy in GPS RTK, precision analysis about spatial aerotriangulation and proves that it satisfies the demand for proportion of 1:2000.
