摘要
针对现有基于GPS信号的室内定位辅助设备,无法精确地调制与放大GPS信号等问题,该文设计一种塔型室内定位系统,主要包括信号接收机、信号处理机、伪定点基站辅助装置、信号发射机等,该系统能够实时接收GPS信号并计算出伪距误差,从而进一步计算出更精确的定位导航位置,并通过发射机实现GPS信号在室内的分布扩散。
Aiming at the problem that existing indoor positioning auxiliary equipment based on GPS signals cannot accurately modulate and amplify GPS signals,a tower-type indoor positioning system is designed.It mainly includes signal receiver,signal processor,pseudo fixed-point base station auxiliary device,signal transmitter,etc.The system can receive GPS signals in real time and calculate the pseudo-range error,so as to further calculate a more accurate positioning navigation position and pass the transmitter to achieve the distribution and spread of GPS signals indoors.
