The ICE family is a series of radiation-hard, space qualified sets of control electronics initially designed to drive satellite space-based cryocooler systems supporting thermal imaging systems. The ICE family is cooler agnostic, allowing it to be integrated with cryocoolers from multiple manufacturers.
In addition to basic cryocooler control functionality, the ICE family adds multiple options for mission customization and flexibility, including; launch locks, input ripple filter (IRF), and vibration control. The IRF reduces noise perturbation to the input power bus, reducing conducted emissions. The vibration control provides 5-harmonic vibration analysis between the accelerometer or force transducer and the compressor, adjusting the voltage and providing image stabilization.
