Embodiment 1

[0045] like figure 2 Shown is a schematic diagram of the voyage route. The return navigation method provided in this embodiment means that the carrier has set off from the starting point A, arrived at the midway point C or has reached the destination point B, and the user inputs the return operation, and the navigation system will operate The starting point A of the carrier's incoming voyage is used as the destination point of the return voyage, and the destination point B of the incoming voyage of the carrier is used as the starting point of the return voyage to realize the process of returning to the voyage. The specific process is as follows image 3 Shown:

[0046] S101. Receive the starting point and destination point of the incoming voyage input by the user, for example: the starting point is A and the destination is B; if the "return" function of the navigation system is not the default setting, but manual selection is required, then It may be necessary to set the cor...

Embodiment 2

[0058] like figure 2 Shown is a schematic diagram of the voyage route. The return navigation method provided in this embodiment means that the carrier departs from the starting point A, arrives at the halfway point C or has arrived at the destination point B, and the user inputs the return operation, and the navigation system will send the carrier The starting point A of the incoming voyage is used as the destination point of the returning voyage, and the current position of the carrier is used as the starting point of the returning voyage to realize the process of returning to the voyage. The specific process is as follows: Figure 4 Shown:

[0059] S201. Receive the starting point and destination point of the incoming voyage input by the user, for example: the starting point is A and the destination is B; if the "return" function of the navigation system is not the default setting, but manual selection is required, then It may be necessary to set the corresponding function...

Embodiment 3

[0077] like Figure 5 As shown, the navigation device for returning to the voyage provided by this embodiment is suitable for returning to the navigation process in which the starting point of the carrier's incoming voyage is used as the destination point of the returning voyage, and the destination point of the carrier's incoming voyage is used as the starting point of the returning voyage after receiving the returning voyage instruction. .

[0078] The structure of the device specifically includes: an input module 1 , a navigation module 2 , a GPS receiving module 3 , an output module 4 and a return control module 5 , and a return shortcut key 6 is also provided. The return flight shortcut key 6 is connected with the return flight control module 5 (the return flight shortcut key 6 can also be placed in the input module 1, and is connected with the return flight control module 5 through the input module 1), and the user inputs the user's return flight operation through the re...

Abstract

The invention is suitable for the field of navigation and provides a navigation method and a device for return voyage in a navigation system, which uses GPS positioning information for navigation. The method comprises the following steps that: a, after a return voyage instruction is received, the starting point of the ongoing voyage of a carrier is used as the destination point of the return voyage, and the destination point of the ongoing voyage of the carrier or a current position is used as the starting point of the return voyage; and b, a navigation system plans a path for navigation of return voyage according to the reset starting point and the reset destination point of the return voyage as well as GPS positioning information. By using the technical proposal of the navigation method, a user only sends a return voyage command and the navigation system starts the navigation of the return voyage automatically. Thus, the navigation method solves the problems of complicated operation and inconvenient use for the user caused by repeated input of the place of departure and destination for return voyage of the prior navigation system. The navigation method can further realize navigation setting for returning to the destination by using one key, reduce the operating steps of the navigation setting, prevent the user from influencing the control of the carrier because of entering the place of departure and the destination manually in the navigation process of the carrier, and improves the security of the navigation of the carrier.

Description

technical field [0001] The invention belongs to the technical field of navigation, in particular to a navigation method and device for returning to a navigation system. Background technique [0002] GPS (Global Positioning System, Global Positioning System) satellite navigation means that the GPS antenna of the GPS navigation system receives the navigation and positioning information transmitted by at least 3 of the 24 GPS satellites around the earth, and guides the carrier (aircraft, ship, vehicle) The process of navigating from one point to another. [0003] For any specific navigation process, it is necessary to determine the movement parameters of the vehicle (starting point, destination point, current position, direction of movement, and speed, etc.) to ensure that the vehicle completes the scheduled voyage. Usually, first determine the starting point (departure point), destination point (destination) and navigation route of this voyage (it can be the route determined ...
