摘要
基于我们的车载 DGPS试验成果和 DDKIN动态载波相位测量数据处理软件,本文主要论述了 GPS 动态定位的下列技术问题:依据 GPS卫星给用户提供的 User Range Accuracy值,选择定位星座;顾及运动载体的特点,选用 GPS信号接收天线及其在载体上的安设位置;用 Trimvec Plus和DDKIN 软件,精细处理一秒数据率的动态载波相位测量数据。
On the basis of DDKIN software for processing kinematic observations on carrierphases and results for a vehicle-borne DGPS this paper discusses the following performancesfor GPS kinematic positoning: ——to select a suitable positioning constellation to consider the User Range Accuracies(URA) provided by the navigation message of GPS satellites: ——to make choise of a suitable antenna and its setting-up site based on features of themotional carrier: ——to process finely 4000SST data at the update rate of one second to adopt TrimvecPlus and DDKIN software written by these authors.
