摘要
GPS定位中需要计算出卫星位置信息来确定用户位置。为快速准确定位,必须得到精确的卫星位置。分析了GPS广播星历,提出了一种利用广播星历和迭代法计算GPS卫星位置的方法,该方法解算速度快、准确度高。
GPS orientation need calculate GPS satellite position information which can ascertain user position. In order to orient fleetly and veraciously, user must get GPS satellite position exactly. The paper analyses the GPS broadcast ephemeris, and presented a new method which calculate GPS satellite position utilizing the GPS broadcast ephemeris and iterative technique. The way has fast calculation speed and high nicety.
