Abstract在软件接收机的架构下,实现了GPS和CAPS单模软件接收机的定位解算,在分析GPS和CAPS导航系统之间卫星识别方式、测距码及扩频方式、时间坐标系、空间坐标系、载波频段及导航电文异同的基础上,提出了一种GPS/CAPS双模软件接收机结构.在此结构上,使用两套天线分别接收真实的GPS和CAPS射频信号,基于计算机Matlab软件平台,完成全部基带信号处理以及定位计算等完整过程,实现GPS和CAPS单模导航系统和GPS/CAPS双模导航系统3种情形下的定位实验,并对定位结果从准确性和稳定性两个方面进行了分析论证.实验结果表明,CAPS定位精度与GPS定位精度大致相当,GPS/CAPS双模软件接收机定位结果精度比GPS和CAPS单模软件接收机定位结果精度高1-2m,同时GPS/CAPS双模软件接收机定位结果的平均方差最小.
