The Study On Application Of Multi-mode Satellites Navigation Location Technology In Precision Forestry

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.
