Abstract
The utility model relates to a GPS (Global Positioning System) and big dipper dual-mode vehicle-mounted navigator, which comprises a GPS navigation host. The GPS navigation host comprises a GPS satellite positioning module, a main controller, a display and drive unit, a display module and an input control unit; and the GPS and big dipper dual-mode vehicle-mounted navigator further comprises a big dipper satellite positioning module, wherein the big dipper satellite positioning module is electrically connected to the GPS navigation host. The GPS and big dipper dual-mode vehicle-mounted navigator makes up the deficiency of two positioning systems, and the big dipper satellite positioning module serves as peripherals and can be flexibly selected by users, so that the purchasing pressure on users is relieved, the threshold for the use of a big dipper system is lowered, and the GPS and big dipper dual-mode vehicle-mounted navigator is beneficial to advancing the civil process of the big dipper system and promoting the big dipper system to exert social benefits earlier, and plays significant roles in meeting the demands of the development of national security and economic society on satellite navigation systems, promoting the transformation of modes for national information construction and economic development and realizing the social and economic benefits of the satellite navigation industry.
Description
Technical field
The utility model relates to the navigating instrument technical field, particularly relates to a kind of GPS and Big Dipper bimodulus automatic navigator.
Background technology
Operable navigational system mainly contains big-dipper satellite Dao boat Xi Tong ﹝ BeiDou (COMPASS) the Navigation Satellite System ﹞ of GPS of USA (global positioning system global positioning system) and China's independent research in China domestic scope at present.Wherein gps system possesses the bearing accuracy height; Advantages such as wide coverage; But because this system is the control of the military of other country; Can think under specific circumstances increases its positioning error or it was lost efficacy, and the end product of applying GPS only possesses the ability of unidirectional reception locating information in addition, lacks the interactive communication between terminal and system.
Beidou satellite navigation system is the Chinese independent development capability of implementing, the GPS of independent operating.Launched 9 satellites at present, system has possessed location, navigation and time service and the short message communication service capabilities that covers the Asian-Pacific area; The year two thousand twenty left and right sides is covering the whole world.Dipper system is devoted to global user location, navigation and time service service to be provided, and bearing accuracy is 10 meters at present, rate accuracy 0.2 meter per second, 10 nanoseconds of time service precision.The present bearing accuracy of this system is low, and the shortcoming that coverage is little has also hindered by more products and adopted.
Therefore, how to realize the location navigation of the wide scope of high precision, can take precautions against other country's human intervention positioning function again, guaranteeing simultaneously can effective communication between terminal and system.Become a great problem of current generation China's development autonomous navigation system.
