DOWNLOAD SPEC SHEET

The ICE-G2 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-G2 family is cooler agnostic, allowing it to be integrated with cryocoolers from multiple manufacturers.

In addition to basic cryocooler control functionality, the ICE-G2 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.

 ICE-G2 ARCHITECTURE HIGHLIGHTS

  • GaN FET power driver

  • FPGA logic controller

  • Iris patented active vibration control algorithm expanded to multiple CCEs 

  • Reprogrammable software allows customization to unique mission needs
