Research & Development Of The Testing System Of The Nutation Frequency Of The Location Marking Device

The main tasks of missile seeker are target signal detection,getting information and forming control directives. The missile seeker is a key installation and directly related to the combat effectiveness of the missile. The Location Marking Device is an important component of the device, usually consist of infrared optical system, Gyro tracking institutions components, which is used to measure the angular velocity of antenna and other parameters to provide target coordinates information and necessary guidance for the information seeker.High-precision navigation and guidance systems have very strict requirements of the device. However, due to positioning in the processing and distribution of materials, assembly error, causing his centroid was not in its rotation axis. Under the force of gravity, the rotating rotor in the process produce a campaign together. This will make joint efforts in the rotation axis gyro location near a cyclical theory of minor changes that is Nutation. This will affect the measurement accuracy. The test system is...
