采用加速度传感器技术实现盲区定位的研究和开发

RESEARCH ON AND DEVELOPMENT OF BLIND SPOT POSITIONING RELYING ON ACCELERATION SENSOR

GPS是目前应用最广泛的定位技术,但动态环境和遮挡区域会造成接收机不能捕获和跟踪GPS信号,导致GPS功能失效,从而无法进行正常定位。采用加速度传感器与GPS相结合的方式,在GPS获得初始基准位置后,利用多种加速度传感器获取人员方向和速度等位置信息,根据获得的人员位置信息进行定位航位推算,从而实现在GPS盲区的定位。

GPS is currently the most widely used positioning technology,but when there is a dynamic environment or a sheltered area,the receiver may fail to capture and pursue GPS signals,so that GPS itself may fail to function,hence resulting in failure for correct positioning.The combination of acceleration sensors with GPS is accepted.When GPS obtains the initial reference position,various acceleration sensors are used to obtain position information such as staff direction,speed and so on.According to the obtained staff positioning information,location dead reckoning is executed in order to achieve GPS blind spot positioning.
