Abstract

The invention relates to a high-precision self-locating system, which relates to the field of locating system technology. In order to help a launch vehicle to realize high-precision locating inside a service site of the launch vehicle, the high-precision self-locating system adopts the following technical measures: a computer, an infrared receiving device, an electronic milemeter and an azimuth angle measuring device are arranged on the launch vehicle; the infrared receiving device, the electronic milemeter and the azimuth angle measuring device are connected with the computer at the same time; an electronic plane figure of the service working site of the launch vehicle is installed on the computer; at least one infrared coordinate launching point is arranged on or under the service working ground surface of the launching vehicle for automatically inputting coordinates of the point to the computer of the launching vehicle passing the point. Therefore, the high-precision self-locating system has the advantages that the launching vehicle loaded with the system can accurately record the tracks by virtue of the equipment on the vehicle. The electronic plane figure of the current service site of the launching vehicle is loaded on the computer, the coordinates of the site of the system is input into the computer, and then the computer can realize high-precision locating.

Description

technical field [0001] The present invention is one field of positioning system technology. Background technique [0002] When it comes to positioning and navigation, people will naturally think of the widely used satellite positioning and navigation technology in the prior art. But there are some occasions where satellite positioning and navigation technology cannot be used. For example, large supermarkets in indoor environments, factory workshops, and some places that require high positioning accuracy. Since these places are generally indoors, it is difficult to receive signals from positioning satellites. On the other hand, although some places are outdoors, the errors of satellite positioning generally cannot meet the positioning accuracy requirements of these occasions, so they cannot or are not suitable for using satellite signals for positioning; There are also technologies such as infrared positioning technology and ultrasonic positioning technology, but when the...
