2.3 Functional Description
2.3.1
TCU Electro Mechanical architecture
The TCU consists of a motor driven outer gimbal that is free to move in the azimuth and
elevation axes. The TCU also consists of an inner gimbal which is free to move in the
azimuth and elevation axes and driven directly by torque motors. The inner gimbal
supports the Thermal Imager, TV camera, Laser Range Finder and Spotter Scope
payloads which are isolated from aircraft vibrations. The stabilization of the image
sensors is achieved using closed loop motor servos on the inner and outer gimbals.
To maintain the gimbal in the STOW position when the TCU is powered down, a
mechanism using permanent magnets is used to prevent the gimbal from moving. This
arrangement utilizing a powerful magnetic circuit attracts the inner axis towards the
outer axis when in the STOW position.
