摘　　要：通过对全球定位系统(GPS)伪距导航定位原理的深入研究,探讨了GPS用于飞行器外弹道测量的两种工作模式和相应的特点及应用领域。通过实测数据计算表明,GPS弹道精度优于常规弹道精度,GPS用于外弹道测量系统具有可行性和实用性,有很好的应用前景。Through the deep research into the theory of global positioning system （GPS） pseudo distance navigation and positioning principle, disscussion on two kinds of work modes with their characteristics and application fields of GPS in the aircraft trajectory-measuring system is presented. The computed result of flying experiment data indicates that GPS trajectory precision is better than the general, and GPS using in the outer-trajectory measurement system is provided with the feasibility and practicability and has a wide application prospect.
