High dynamic environment may cause a large Doppler shift, thus the general GPS receiver is difficult to work reliably without outside assistance.
高动态环境会造成较大的多普勒频移，这使得一般的GPS接收机在没有外界辅助的情况下难以可靠工作。
At the same time, on the request to the data refresh rate in high dynamic environment, the paper deduces the rapid extrapolation algorithm of the orbit to replace dynamic model method.
同时，由于高动态环境下对数据更新率的要求，推导出轨道快速外推公式替代动力学方法来计算卫星的在轨位置。
With its dynamic multi-threading architecture, IDS scales well and can manage very large volumes of data, providing high performance in the OLTP environment.
