Abstract

The invention discloses a high-accuracy detection and calibration device and method of inertial orientating equipment. The device comprises a positioning and orientating resolving processing system, a display control terminal, a mobile station bracket and a reference station bracket, wherein the positioning and orientating resolving processing system consists of a GPS (Globe Positioning System) mobile station and a GPS reference station; the display control terminal is connected with the positioning and orientating resolving processing system in a wireless way; the upper end of the mobile station bracket is provided with a mobile station aiming tool connected with the GPS mobile station; and the upper end of the reference station bracket is provided with a reference station aiming tool connected with the GPS reference station. By adopting the high-accuracy detection and calibration device and method of the inertial orientating equipment, calibration of the inertial orientating equipment is realized by adopting a satellite orientating technology, and limits on the detection and calibration of the inertial orientating equipment due to adoption of a true north or indirect true north finding reference method are complemented; a static relative positioning and orientating method is adopted, so that limits of regions and environments are eliminated and flexible movement is realized; and the device and the method have the advantages of high positioning accuracy, high cost performance, easiness of operation, convenience of using and the like.

Description

technical field [0001] The invention relates to a detection and calibration device and a method thereof for orientation equipment, in particular to a high-precision detection and calibration device and a detection and calibration method for inertial orientation equipment. Background technique [0002] At present, most of the autonomous orientation equipment commonly used in the military is based on the principle of inertial measurement, that is, the use of high-precision gyroscopes to sense the horizontal component of the earth's rotation motion, and according to the change law of the angle between the sensitive axis and the north direction, the data is processed to obtain the true north direction , in this kind of equipment, parameters such as the zero position and scale factor of the gyroscope will change with the storage time and the use environment, and drift with the temperature, which is determined by its physical characteristics. This characteristic of the gyroscope is...
