The Airborne Signals Intelligence Payload (ASIP Family of Sensors) is a next generation signals intelligence
sensor(SIGINT) for the U.S. Air Force. ASIP delivers enhanced signals intelligence capabilities
to the warfighter. It detects, identifies and locates radar and other types of electronic
and modern communication signals. A key attribute of the ASIP payload is an open,
scaleable architecture that allows future system upgrades to be easily added and
sensors readily reconfigured in support of evolving warfighter needs.
SprayCool® is a subcontractor to Northrop Grumman Mission Systems sector's Electromagnetic
Systems Laboratory (ESL) business unit. In support of the program, SprayCool currently
provides 20-slot chassis for both the manned U-2 Dragon Lady and RQ-4 Global Hawk
UAV variants. SprayCool has also been contracted to provide a version of its multi-platform
enclosure (MPE) enclosure for MQ-1 Predator aircraft under the ASIP-1C contract.
Key attributes of SprayCool thermal management systems for the ASIP family of sensors
include the ability to operate sensor electronics in harsh environments. This includes
operations in cold environments up to 70,000 ft. elevation in unpressurized compartments
of the Global Hawk and U-2. To do this, SprayCool incorporates heaters in the chassis
which enable operation of COTS electronics at these extremely harsh environments.
Another advantage of SprayCool enclosures is the ability to maintain a narrow temperature
range during operation. This is extremely beneficial when deploying RF components.
Three ASIP sensors completed flight testing on the U-2 in 2008 with operational
fielding expected in 2009. The Global Hawk variant of the ASIP sensor will complete
flight testing in 2008 and begin production in 2009 with operational fielding expected
in 2011. Testing for the Predator’s ASIP-1C sensor is expected to begin in
2008 as well.
