Satellite positioning and network positioning dual-positioning vehicle-mounted navigation apparatus

Abstract

The invention discloses a double positioning vehicle-bone guider of satellite positioning and network positioning, which pertains to the technical field of automobile guiders. The technical problem to be solved is providing a double positioning vehicle-bone guider adopting the satellite positioning and the network positioning. The technical proposal to solve the technical problem is that: the satellite information input end of a central processing circuit is connected with the satellite information output end of a satellite information receiving circuit; the processing signal input end of a network information receiving circuit is connected with the processing signal output end of the central processing circuit, a network information output end is connected with the network information input end of the central processing circuit; the positioning information processing signal input end of a network positioning information processing circuit is connected with the positioning information processing signal output end of a network information receiving circuit, a positioning information output end is connected with the satellite information input end of the central processing circuit. The invention is applied to a vehicle-bone guider, and has the beneficial effect of solving the positioning when the satellite signal is weak, with no-mass storage device, low construction cost and convenient usage.

Description

technical field [0001] The navigation device belongs to the technical field of car navigation devices. Background technique [0002] In order to make it easier for car drivers to determine a fast road from one city to another, vehicle navigation devices are currently used both at home and abroad. The disadvantage of the prior art car navigation device is that in order to determine the driving route between cities, the car navigation device must store the maps of multiple cities and must be updated frequently. For this reason, the car navigation device needs to have a large-capacity storage device , leading to high prices, the current price is about 10,000 yuan, and the average user is unwilling to use it; and in some cases, such as in an underground garage or between high-rise buildings in the city, the satellite signal received is relatively weak, and navigation The device also cannot be properly positioned.
