摘要
全球卫星导航系统(GNSS)发展对用户设备的信息兼容性提出了更高的要求,同时对设备存储空间以及运算能力的需求增加,而受成本和功耗等因素影响,处理资源不可能无限制地扩充。针对该问题,在GNSS设备信息层设计了一种兼容的卫星星历解析方法,并在微型嵌入式平台上进行了验证。该方法能够提高嵌入式系统的RAM资源利用率,节省CPU的运算资源。便于GNSS接收机程序开发与后续升级,满足兼容性要求。
The development of GNSS requires more compatibility for popular facilities.And more demanding requirement on memory and computing velocity has been needed for various applications.Limited by factors such as cost and power consumption,resources would never be expanded for all time.Therefore,a novel realization method is designed for GNSS ephemeris real-time decoding.And it is validated on embedded platform.The method can enhance the utilization of RAM and save the time resource of CPU in embedded system.Users can conveniently achieve the GNSS receiver program and expand interface and satisfy the compatibility of GNSS receivers.
