摘　　要：针对靶场外弹道测量采用的GPS单参考站差分定位技术无法满足长基线的精密定位要求的状况,提出基于虚拟参考站技术(VRS)的精密测量方案。通过对靶场VRS系统进行设计并推导出其定位的数学模型,最后分析VRS定位中的主要误差源对系统精度影响,论证了该方案可以完成导弹外弹道高精度、高可靠性和高覆盖范围的实时动态测量要求。For the problems that trajectory measurement of range adopted single station differential GPS positioning technology which couldn’t meet the demand of precise positioning on long-baseline,the precise measurement project based on Virtual Reference Station（VRS）is proposed.The range’s VRS system is designed and its mathematics model is educed at the same time.The influence caused by the major errors to measurement accuracy is analyzed in the end.The project could achieve high precision,reliability and large scale of the real-time and dynamic measurement of trajectory.
