Navigation method and device and navigator

Abstract

The invention provides a navigation method and device and a navigator. The navigation method comprises acquiring a work mode of a portable device according to a received input instruction, acquiring and storing current position information in real time at preset time period intervals and displaying the current position information through a display mode corresponding to the work mode. The device is free of map data and a mobile communication module so that potential safety hazard caused by a poor map precision and a poor mobile signal is reduced.

Description

technical field [0001] The present application relates to the technical field of navigation, in particular to a navigation method and device thereof, and a navigator. Background technique [0002] With the improvement of people's living standards, outdoor travel has become a mainstream way of leisure, and the safety of outdoor travel has attracted more and more attention. In order to avoid danger due to getting lost during outdoor travel, people usually use a navigator to implement road guidance. [0003] However, the usual navigator only locates the current position, and the map of the corresponding area needs to be downloaded in advance. In special cases such as deep mountains, the maps downloaded in advance are only approximate topographic maps, not detailed, and the forward route cannot be determined. Moreover, in the deep mountains, the mobile signal is usually poor, so it is easy to be in danger due to the inability to communicate with the outside world, and there ar...
