摘要
导航卫星广播星历是卫星导航定位的基础,要求有较高的精度和实时性。利用广义延拓插值法来拟合GPS导航卫星轨道,插值系数作为广播星历的参数发播,是一种新的广播星历形式。而且具有精度高,计算快捷等特点,另外对于具有其他多种轨道类型共存的导航系统来说也具有一定的参考意义。
The broadcast ephemeris, which is the basic of satellite navigation and position, must be precise and real time. A new form of broadcast ephemeris of satellite is developed which adopts the generalized extension interpolation to fit the orbit of navigation satellite and then the fitted coefficients are broadcasted as broadcast ephemeris. And this ephemeris can be calculated more higher accuracy, easily and quickly.
