A Short-line Extended Heading Determination System based on GPS

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.
