Title: PRECISE POSITIONING SYSTEM, AND BASE STATION AND SELF-MOVABLE ROBOT SYSTEM THEREOF
Abstract:
The present invention relates to a high precision positioning system for an outdoor robot, comprising: a base station and a mobile station arranged on the robot. The base station comprises a first antenna, a first control module and a first communication module; and the base station receives a radio frequency signal sent by a satellite positioning system via the first antenna, and generating positioning reference data and transmitting same to the mobile station. The mobile station receives the radio frequency signal sent by the satellite positioning system via a second antenna, and receives the positioning reference data transmitted by the base station, so as to obtain precise positioning data of the mobile station. The base station further comprises an antenna location adjustment apparatus, and the antenna location adjustment apparatus sets the location of the first antenna in an adjustable manner. The base station further comprises an antenna location indication apparatus, for indicating an ideal mounting location or an ideal height of the first antenna. The beneficial effects of the present invention are: enabling the amount of satellites shared between the mobile station and the base station to be greater than or equal to a pre-determined amount, and improving the operation reliability of the high precision positioning system.
