The EXA ICEPS is designed to be the central operational heart of CubeSats, enabling modular use of higher performance hardware and features. ICEPS compresses the functions of many cards into a single, 25mm-thick system, using modularity for fully customizable hardware that can range from being simply an EPS or including a range of features.

ICEPS can interface and work with any compatible USB hardware, but it is designed to optimally operate in conjunction with EXA-developed hardware, like BA03 Battery Arrays, DMSAs (Deployable Solar Panel), and SEAM/NEMEA shielding. ICEPS is also the system core of the EXA's KRATOS spacecraft bus, including all of these components. Although initially designed to handle requirements for a 1U CubeSat, ICEPS is ready and able to handle all these requirements for larger CubeSat missions.

ICEPS is set to launch on IRVINE03 onboard the NASA ELaNa launch in Q4/2021, on IRVINE04 onboard ELaNA also in 2022, on K'OTO onboard HTV for Q3/2021, and onboard INSPIREFLY for 2022. It is also the system core of an upcoming lunar mission onboard the Astrobotic Peregrine Lander, set to land on the moon in Q3/2021.

The central features of the system core include:

  • Embedded laser communications
  • Integrated Epik Z2 OBC with 2 SDR radios
  • USB and I2C bus
  • SSD storage up to 512GB
  • Automatic control of deployables
  • 100W capable EPS
  • 6-axis IMU
  • ITAR free product

ICEPS is delivered with:

  • Full engineering support
  • Test reports and ICD
  • Interface custom cables
  • Choice of aluminum spacers M2.5
