摘要:

针对无线Ad Hoc网络节点定位中采用单点GPS定位方法精度不高的问题,提出一种相对GPS方法。在控制网络中,各节点在同一时刻采用相同的卫星组合进行GPS定位并计算节点间的相对位置,可以大大消除定位的系统误差,提高相对定位精度。由于不需要固定基站,该方法适合于移动Ad Hoc网络节点定位的应用。在Zigbee无线网络平台上对本该方法进行实现与验证,实测结果表明,该方法可以将节点定位精度控制在5 m以内。

Abstract:

In order to improve the positioning precision of wireless Ad Hoc network nodes with spot GPS, this paper presents a GPS method for relative positioning of nodes. The nodes in network get their spot positions with GPS modules calculating synchronously and using the same satellites, and then get the relative positions between nodes which can decrease the measurement errors. The algorithm is suitable for positioning of wireless Ad Hoc network for no GPS base-stations needed. The method is implemented in a Zigbee network platform and experimental results indicate that the positioning error is improved to less than 5 m.

Key words: GPS positioning, wireless Ad Hoc network, relative positioning, Zigbee network
