Abstract

The invention relates to a navigation technology. Aiming at the defect of over high cost in the existing motorcade navigation proposal, the technology provides a motorcade navigation system, a piloting navigation device, an accessory navigation device and a navigation method thereof. the motorcade navigation system comprises a piloting navigation device for receiving the information of a starting place and a destination and generating and sending out a navigation route; receiving satellite navigation signals, calculating and sending out the current position coordinates; the accessory navigation device is used for receiving and displaying the navigation route sent by the piloting navigation device; receiving the current position coordinates sent by the piloting navigation device, thus displaying the current position of the piloting navigation device. The invention further provides the piloting navigation device, the accessory navigation device and the navigation method thereof. The piloting navigation device sends the optimal route to the accessory navigation device, thus leading the accessory navigation device to be only in need of being configured with mobile communication function and displaying function without configuring the navigation device with full function for each automobile in a motorcade, thus reducing the navigation cost of the whole motorcade.

Description

technical field [0001] The present invention relates to navigation technology, more specifically, relates to a fleet navigation system, a pilot navigation device, a slave navigation device and a navigation method thereof. Background technique [0002] Vehicle navigation technology is an important branch of GPS (Global Positioning System, GPS) technology. The working principle of the vehicle navigation system based on this technology is that the vehicle navigation terminal receives the position coordinates transmitted by at least 3 satellites among the 24 GPS satellites around the earth, and compares them with the position coordinates recorded in the electronic map stored in the terminal itself. Matching, in order to determine the exact position of the navigation object equipped with the terminal in the electronic map. [0003] As self-driving tours become increasingly popular, more and more users choose to travel by car in groups. Each self-driving tour team often includes...
