摘要：Global satellite positioning technology has been applied to transport, mapping, security, agriculture, forestry and other fields. In this study, we summarized the application of satellite positioning technology in forestry, pointed out issues of low signal amplitude, and low accuracy of positioning in practical application. This paper introduced the theories of several commonly used assist positioning technologies, such as, Wi-Fi positioning, wireless sensor network positioning and inertial navigation, analyzed its application in forestry base on its characteristics of these positioning technologies, then proposed the technical method of the combining positioning. Designed the locating scheme of forestry based on nature reserve patrol business, and briefly introduced its basic theories. In this study, we analyzed the feasibility of the application of wireless positioning in forestry by control variables and regression analysis. ? (2014) Trans Tech Publications, Switzerland.
