Abstract：In order to meet the needs of highly dense and overall farmland information gathering，wireless data communicating, and real-time processing in the precision agriculture, this system integrated GPS, GIS and RS based on the technology of computer and wireless data transmission. On the one hand, the system makes DGPS and Hyper-spectrograph integrated through the AT89lv52 MCU, providing the accurate space position and realizing the integration of spectrum data acquisition and orientation. On the other hand, the system realizes the communication between the data gathering control system and the microcomputer by using the nRF905 system. Meanwhile the system has realized the visualized analysis and management of the spectrum data by integrating Visual Basic and Map-Objects into GIS, displaying real-time trace of moving point and some related attributes of the moving point in map layers, and calculating crop derivative spectra and crop vegetation index NDVI etc. Thus, sufficient information was provided for expert system and decision support system of precision agriculture.
Key words：Hyper-spectral data gathering;Wireless data communication;Precision agriculture
