Abstract

The invention provides a multi-gyroscope atomic group synchronous control method. The method comprises the following steps of: adding supplementary magnetic field coils in the casting direction of atomic groups, establishing a relation curve of compensation magnetic field voltages and the positions of the atomic groups, measuring atomic group position deviation when an atomic group reaches an interference area and a detection area by taking any gyroscope as a standard, and correcting position deviation by changing the compensation magnetic field voltage to adjust the position of the atomic group, thus realizing synchronous control over the positions of the atomic groups of the multiple gyroscopes. According to the scheme, synchronous control of atomic group positions can be realized, and synchronization of measurement of different axes is guaranteed, so that the cold atom inertial navigation parameter measurement precision is improved.

Description

Technical field[0001]The present invention relates to the field of cold atomic inertia navigation, and more particularly to a multi-tumer group position synchronous control method.Background technique[0002]Compared with satellite navigation, inertial navigation has the advantages of high concealedness, wide application range, and strong anti-interference ability. It is one of the autonomous navigation systems that have become a key research technology in modern military and defense. Inertial navigation relies on the inertial component, mainly the gyro and accelerometers, measures the corresponding inertia (speed and acceleration), thus estimating the motion state and location information to achieve precise navigation. The measurement accuracy of the inertial component determines the accuracy of the inertial navigation, and the cold atomic interference inertial measuring element has a theoretical accuracy of several magnitude of the traditional inertial measuring element, and is one ...
