Title Design of electronic geographic coordinate system Based on RSSI ranging technology

Abstract

In this paper, based on wireless communication technology ZigBee and RSSI ranging technology, design an electronic geographic coordinate system model, which provides reference for the practical application of the electronic coordinate system.

This paper is aimed at improving and correction of GPS navigation system coordinate data using the proposed the overall scheme of the system and on the use of RSSI ranging technology were influencing factors analysis, and the improved algorithm, try to get a more accurate RSSI value in order to ensure the accuracy of the coordinate data.Using CC2530 chip as the core of the ZigBee module, to build a consists of two modules and PC electronic geographic coordinate pile prototype system, and successfully run, two modules normal to send and receive data and can based on RSSI values measured distance. The results proved the feasibility of the design scheme.

Keywords wireless sensor networks ZigBee module distance measurement based on RSSI node localization coordinate correction
