| 摘 要： | 提出了一种组合星座定位的导航终端设计。使用DSP作为控制和数据处理核心,既可以实现北斗二代导航卫星系统(COMPASS)以及全球定位系统(GPS)的单星座定位,又可以实现COMPASS和GPS组合星座定位。由于能够同时利用COMPASS系统和GPS系统,可用卫星数目大大增加。同时,单星座定位算法和组合星座的定位技术的解决,使得导航终端的定位精度和导航的连续性都得到提高。

| Abstract: | This paper proposes a design of navigation terminal for positioning with combined constellation.The design uses DSP as the core of control and data processing.The design can not only implement the positioning with single constellation of COMPASS and GPS,but also implement the positioning with combined constellation of COMPASS and GPS.The quantity of usable satellites is greatly increased because of using COMPASS and GPS at the same time.Owing to the proposed single-constellation positioning algorithm and combined constellation positioning technology,the position accuracy and continuity of the navigation terminal are improved. |
