【摘要】 近年来,随着“精准林业”研究的不断深入,卫星导航定位技术在其中的应用领域不断扩展,同时对于定位的精度要求也不断提高,简单的单机定位已经不能满足现实工作的需要。因此,为了适应“精准林业”的发展要求,将不断创新发展的卫星导航定位技术应用于林业之中,本文着重研究了多模卫星导航定位技术在“精准林业”中的应用前景与相关方法。本文介绍了当前全球卫星导航定位系统的最新发展,着重研究了多模卫星导航定位的关键技术,包括网格化卫星导航定位、网格DGPS/RTK、虚拟网格参考站等技术在林业上的应用;研究了适应林业应用的无缝多模导航定位的关键技术,包括精密单点定位技术、网络RTK技术、卫星定位与惯性导航集成定位技术等;适当探讨了有关适合于林业应用的多模接收机的设计问题;首次将多模卫星定位连续运行服务系统(CORS)引入到林业问题的应用上,探讨建立地区林场级的参考站和数据运行服务系统的可行性。本研究结合目前全球卫星导航定位技术的发展现状与最新趋势,探索性地将多模卫星导航定位新技术引入到林业应用中,为精准林业技术体系的发展及应用提供新的技术支持。满足“数字林业”建设的迅猛发展,实现林业管理的数字化发展。为森林资源监测管理、森林病虫害防治、森林防火等诸多领域提供要求越来越高的定位技术与位置服务。更多还原

【Abstract】 In recent years, with the in-depth research of the "precision forestry", satellite navigation and positioning technology have expanded their application field in it. While the requirements of accuracy of the positioning have been increased, the simple single location has been unable to meet the needs of practical work. Therefore, in order to adapt to the requirements of the development of the "precision forestry", and take the satellite navigation and positioning technology which continue to innovate and develop apply in the forestry, this paper mainly studied the application foreground and related methods about applying multi-mode satellite navigation and positioning technology in the "precision forestry".This paper introduced the last word of the global navigation satellite system (GNSS), mainly studied the key technology of multi-mode satellite navigation and positioning, including the technology apply in forestry such as grid of satellite navigation and positioning, grid DGPS/ RTK, virtual grid reference stations, and so on.It studied the key technology of the seamless multi-mode navigation and positioning which fit to the application of forestry, including the precise point positioning technology, network RTK technology, satellite positioning and inertial navigation system (INS) technology integration. The design of the multi-mode receiver, which is suitable for was also discussed. The multi-mode global navigation satellite system continuously operating reference stations (GNSS CORS) was introduced into the application of forestry issues for the first time.It studied the feasibility of establishing the reference stations at the regional forest farm-level and the data running services system.This research introduced new technology, multi-mode global satellite navigation and positioning, into the application of forestry exploringly, with integrating actual status and latest trend of global navigation satellite system.It provided new technical support to the development and application of the "precision forestry" technical system.It met the rapid development of“digital forestry”construction, and achieved digital development of forestry management.So, the positioning technology and location services, which are required higher and higher, can be provided to many fields such as forest resources monitoring management, forest pest management, forest fire prevention,and so on.更多还原
