基于北斗多模导航定位系统在林业中的应用研究

The Forestry Industry Application Research Based on BD Multi- mode Navigation and Positioning System

鉴于林区卫星导航定位及数据传输相对困难,本文设计开发了集北斗、GPS、GLONASS等卫星定位导航系统于一身的林业行业应用系统,针对林业行业管理需求,兼顾适用、经济、安全、开放的原则进行开发,有效地克服了林区对GPS定位信号的屏蔽和通信信号的阻挡,较好地发挥了北斗导航的主导作用和其他定位系统的互补优势,实现了最初的设计目标,经使用验证效果良好。

Because the satellite navigation and positioning and the data transmission is relatively difficult in forest region, so this paper designed and developed a forestry industry system which integrated the BD and GPS, GLONASS satellite navigation and positioning system, in view of the manage demand in forestry industry, and with the principle of applicable, economic, security and open, the system was development, which effectively overcome the shielding of the GPS signal and communication signal block in forest region, and better play the guiding role of the BD navigation and positioning system and other complementary advantages, achieved the original design goals, it has been verified that the using effect is good.
