Design and experiment of locating system for facilities agricultural vehicle based on wireless sensor network

Some problems of facility agriculture machinery locating system still exist now, such as poor stability, low positioning accuracy and high cost. In addition, agricultural machinery navigation and positioning system based on Global Position System (GPS) is widely used at home and abroad. In order to resolve these problems, a wireless sensor network (WSN) locating system based on NanoPAN5375 module was designed. On one hand, the results of ranging experiments have shown that the ranging accuracy of the nodes based on NanoPAN5375 module is high. Within the scope of the appropriate distance, point-to-point ranging accuracy between the nodes can reach 1.02 m or less. On the other hand, the results of positioning experiments indicate that the stability of WSN positioning system based on NanoPAN5375 is good and the positioning accuracy is high.
