摘要
针对目前导航系统非隐蔽性、抗干扰能力弱、机动性不高,以及对精确定位信息加密等问题进行分析研究,设计能够接收多种卫星系统信息的车载定位导航系统,可实现精确定位,减少定向误差,并具备所需的加密和隐蔽特性。以接收模块和计算模块为核心部件,实现复杂的信号接收、计算和显示功能。介绍了系统总体布局、相关硬件电路和软件结构。实践证明该系统可有效解决上述难题。
Non concealment, weak anti-jamming ability, weak mobility, information encryption of precise posi- tioning in navigation system are analyzed and studied. The vehicle location and navigation system is designed to receive multiple satellite system information, which can precisely position, and reduce the directional error and has characteristics of encryption and invisibility. It can realize complex signal receiving, calculation and display function, which takes receiving module and computation module as the core. The overall layout of the system, hardware structure and software structure are introduced. All above mentioned problems can be solved by the system.
