AN/USQ-78A and AN/USQ-78B Display Control Units Equipping the U.S. Navy's P3-C Orion surveillance aircraft
Aboard many of the U.S. Navy's P-3C Orion maritime surveillance aircraft, AN/USQ-78A and AN/USQ-78B Display Control Units (DCUs) operate as integral components of the aircraft's Single Advanced Signal Processor (SASP). The system is responsible for command and control of the signal processors, drives the displays and controls for two sensor stations, provides acoustic contacts to the Tactical Sub-system, and communicates with other acoustics subsystems.
AN/USQ-78A and AN/USQ-78B DCUs have been installed in the context of the U.S. Navy's Block Modification Upgrade Program (BMUP) and its Anti-surface Warfare Improvement Program (AIP).
At the heart of each AN/USQ-78A or AN/USQ-78B DCU, the LynxOS® real-time operating system can be found running on a Cetia commercial-off-the-shelf (COTS) processor. LynxOS was chosen because it is a hard real-time, POSIX®-conformant operating system.
