Synthesized UHF Computer Controlled Equipment Subsystem [SUCCESS]

The SUCCESS UHF radio is a fully automated microprocessor based, computer-controlled UHF radio. Data may be transmitted and received simultaneously over its one transmit and three receive channels. Two SUCCESS radios may be stacked to provide an integrated, fully redundant, two transmit and six receive channel capability. The radio is designed to communicate with selected airborne, terrestrial, and satellite systems. It contains a Tactical Receive Equipment (TRE) processor and can process up to four simultaneous TRAP and TADIXS-B formatted transmissions. The system is designed for ground or mobile sheltered environments. The DIA accredited communication subsystem is compatible with TROJAN, MSE, DIN or DSSCS, as well as all Tactical Exploitation of National Capabilities (TENCAP) systems. SUCCESS is interoperable with a wide range of existing UHF radios and meets JCS requirements for FLTSATCOM interoperability. Developed for the US Army and Air Force, and fielded in numerous tactical electronic systems such as the AN/TSQ-134 (V) EPDS, SUCCESS provided the round-the-clock, critical communications performance needed during Operations Just Cause and Desert Storm.
