Abstract

The invention discloses a positioning device which comprises a real-time clock module and a clock correction module, wherein the real-time clock module is used for recording system time of the positioning device; and the clock correction module is connected with the real-time clock module and is used for receiving a correction signal from a testing system to ensure that the system time recorded by the real-time clock module is restored into initial time. The invention also discloses a system and a method for testing the positioning device. By the method and the system of the invention, the time correction can be completed before the positioning device is sold.

Description

technical field [0001] The invention relates to a positioning device, in particular to a positioning device, a testing system and a testing method for testing the positioning device. Background technique [0002] The Global Positioning System (GPS) is a medium-distance circular orbit satellite navigation system. It can provide accurate positioning, speed measurement and high-precision time standard for most of the earth's surface (98%). [0003] Developed and maintained by the U.S. Department of Defense, the Global Positioning System can meet the needs of military users located anywhere in the world or in near-Earth space to continuously and accurately determine three-dimensional position, three-dimensional motion and time. The system includes 24 GPS satellites in space; 1 master control station, 3 data injection stations and 5 monitoring stations on the ground and the positioning device as the client. At least 4 satellites are needed to quickly determine the location and ...
