一种可扩展的短基线GPS航向测量系统

A Short-line Extended Heading Determination System based on GPS

设计了一套可扩展的短基线GPS航向测量系统,给出了基于工控机的硬件结构。根据航向解算原理设计了模块化的系统软件,实现了数据接收与航向解算功能的分离,提高了系统扩展性,使系统可以采用两种不同类型GPS接收机进行测量。静态测试表明,证明系统测量精度高,系统扩展性好。

A short-baseline extended heading determination system based on GPS is designed,and the hardware structure of this determination system adopting industrial computer is presented. According to the principle of heading determination,the system software with modularized function structure is designed. The system can receive the measurement data from two different kinds of GPS receivers,and can calculate the parameters for heading determination independently. The high measuring accuracy and good scalability of this designed system are testified by the static experiment under the realistic environment.
