摘要
通过对三台测量型差分GPS和两台航海型GPS在同一测试点进行同时观测,分别得到300组观测数据,并对这些数据进行计算分析,分别得到两种类型GPS的实测航向,以验证航海型GPS用作航向指向系统研究的可行性。经过计算得到,航海型GPS的平均航向为140.6134,°航向的最大偏差为3.6227,°测量型差分GPS的平均航向为141.2193°,航向的最大偏差为1.2155°。分析表明,该方法可行。
This paper, through the simultaneous observation of three sets of measurement type DGPS and two sets of navigational type GPS at the identical testing point, obtains 300 groups of survey data respectively. It also calculates and analyzes these data, and gains the actual course of the two types of GPS, which can be used to verify whether it is feasible for navigational type GPS to be served as a course indicator. By calculation, the conclusion goes as： The average course of navigational type GPS is 140. 6134°, and the maximum deviation of its course is 3. 62271° ; the average course of measurement type DGPS is 141. 2193°, and the maximum deviation of its course is 1. 2155% Analysis shows that the method is available.
