摘要
传统的GPS差分定位存在着差分作用距离有限、可靠性低、可扩展性差等缺陷。虚拟参考站技术(VRS)通过一定的网络协议实时的向服务区域内的所有GPS流动站用户播发根据其多基站网络计算出的GPS差分信息,这些改正信息是针对流动站当前位置的改正信息,从而大大提高了大范围内GPS定位的精度和稳定性。本文对VRS基本原理、运行过程进行了分析,并进一步探讨了该技术在各个领域的应用潜力。
Bluetooth technology provides low-cost,low-power,short-range wireless communication,Constitutes the personal network of a fixed or mobile network environment,and it enables each kind of information equipment to be able to realize the seamless resource sharing in the short distance.Due to the unique technology characteristic and superiority of bluetooth technology,it 's application scope is extremely widespread and has the good prospects for development.
