Abstract

The invention provides a self-adaptive return method and a self-adaptive return system based on Beidou navigation system, and relates to the technical field of navigation. The method includes the following steps: in an advancing process of the user, an NMEA (National Marine Electronics Association) message is obtained from the serial port of the Beidou navigation system once at intervals, and the NMEA messages are parsed to obtain the longitudinal and latitudinal position information of the user at different times and generate the advancing track of the user; when a return instruction inputted by the user is received, according to the current position and advancing track of the user, a prompt message is outputted to the user, and the user returns smoothly according to the prompt message. The invention can ensure that the user can accurately and quickly return when getting lost, moreover, the invention does not require the user to manually set a return destination, so that the operation is simple, and the navigation cost is low.

Description

technical field [0001] The invention belongs to the field of timely navigation, and in particular relates to an adaptive return method and system based on the Beidou navigation system. Background technique [0002] With the improvement of people's living standards, outdoor leisure activities are becoming more and more popular. More and more people participate in activities such as mountaineering, hiking and field adventures, and they can also exercise while relaxing. However, when people carry out these activities, they often get lost in the process of returning to the voyage. For this reason, many outdoor leisure enthusiasts are equipped with GPS navigation equipment. When they find that they are lost during the return process, they can use the GPS navigation equipment to locate the current position, and then manually input the return destination. The GPS navigation equipment can plan the return flight for the user. However, this way of returning to the voyage requires the...
