摘    要:接收机伪距与伪距率的计算和误差补偿是进行北斗系统应用开发的关键之一。本文利用北斗卫星播发的星历等导航电文数据,计算得到北斗卫星位置与速度等信息,对接收机伪距误差补偿,并计算得到伪距率。利用卫星的位置、速度,得到伪距和伪距率的误差值,验证了伪距和伪距率的有效性。

关 键 词:北斗卫星导航系统  星历  伪距  伪距率

Abstract:In the use of BeiDou Navigation Satellite System (BDS), receiver pseudo-range and pseudo-range rate computation and error compensation are important. This paper gives the method for computing BeiDou satellite position and velocity and compensating the receiver pseudo-range error and pseudo-range rate error by using the ephemeris data which broadcasted in NAV message. According to satellite position and velocity, remain error of pseudo-range and pseudo-range rate is obtained, it verify the practicality of the compensated pseudo-range and pseudo-range rate.
Keywords:BeiDou navigation satellite system  ephemeris  pseudo-range  pseudo-range rate
