Description

technical field [0001] The invention belongs to the technical field of space navigation control, and in particular relates to a navigation inertial group indexing and locking mechanism which is self-locked by an electromagnetic brake coordination mechanism. Background technique [0002] From the completion of assembly to the launch of the missile, it must be self-calibrated to ensure that the error of the navigation inertial group test data is smaller and the flight direction is more accurate. The inertial group indexing / locking mechanism is an important part of the navigation inertial group self-calibration system. Its function is to control the navigation inertial group to rotate at a specified angle and lock the specified position according to the calibration requirements. With the wide application of space navigation control technology, the current navigation control system is developing towards higher precision, smaller size and lighter weight. [0003] The inertial gr...
