SATCOM on the Move


Prototype Satellite communication on the move (SATCOM-OTM) chiller developed to mount directly to a moving vehicle and provide a continuous chilled air supply to the inside of a radome.

  • 650 W of cooling in 50°C ambient environment
  • Very short (3.5 inches) to meet the height requirement (overall: 3.5 x 27 x 27 in)
  • Designed specfically to chill the air under a radome

System Description

Aspen’s miniaturized refrigeration technology was adapted to meet stringent height and ruggedization specifications of a vehicle-mounted SATCOM system.  Condensers and evaporators were specially designed for high performance in this low-profile configuration.  Aspen’s standard military control system and miniature compressor were used to complete the design.
