Case study: Radio frequency countermeasures

Eliminating the detectable heat signature from a SOSA supply when it’s not in use

Download the case studyPDF

Customer’s challenge

Migrating to open architecture standards (CMOSS/SOSA) power systems allows for rapid, field-upgradeable countermeasures against evolving threats. A unique challenge is to power the software defined radio card, memory card, and processor card when necessary, yet not draw power when not in use to hide from radar-guided surface-to-air missiles and electronic surveillance. 

  • Draw minimum current when disabled
  • 3U standard form factor
  • Quick prototyping and implementation

The Vicor solution

Vicor VPX solutions are time- and cost-efficient but also eliminate the need for re-engineering and trouble-shooting complex discrete component designs. The system delivers superior performance in the demanding environment of modern armored vehicles. Not only can it be easily modified to meet new requirements, it is also easily modified to avoid detection when the systems it powers are not in use.

主な利点

主な利点

Modified SOSA compliant 3U power supply

Eliminated the heat signature that would endanger the vehicle

Modular approach enabled quick design modifications prototypes

電力供給ネットワーク

Vicor rugged, VITA 62 SOSA compliant OpenVPX power supplies, based on Vicor DCM™ DC‑DC converters, provide not only unrivaled power density and reliability but are also easily configurable. The system was customized to include a quick disconnect circuit to eliminate the heat signature detectable by other forces when not in use.
