Abstract

The invention relates to a navigation method in area which includes: navigation device detects signal for pilotage indicating device, and receives data package sent by pilotage indicating device nearest to the navigation device; the navigation device checks and analyzes the data package to obtain property information of pilotage indicating device stored in the data package; based on property information of pilotage indicating device nearest to the navigation device, destination and electronic map, the process module obtains position of user and navigation path from position of user to destination; obtains current orientation of user, and the process module generates heading direction of current position along navigation path, and compares the heading direction of navigation path with the current orientation of user to generate heading direction of user when user is in current orientation, so effect of navigation in area can be realized.

Description

【Technical field】 [0001] The invention relates to a navigation method used for navigation in a small area, in particular to a method for positioning and navigation using signal transmission between a navigation device and a landmark indicating device set at a fixed position. 【Background technique】 [0002] The current positioning and navigation technology generally adopts the Global Positioning System (GFS, Global Positioning System), which is a global positioning, navigation and timing system composed of 24 satellites launched by the US Department of Defense. Fly around the Earth in six orbits of 20,000 kilometers. There are four satellites in each orbit, and the signals from the four satellites can be received at any point on the earth at any time at the same time, and the space orbit information transmitted by the satellites covers the entire earth's surface. GPS uses navigation satellites to measure time and distance, so that users anywhere on the earth can calculate th...
