The United States Special Operations Command (USSOCOM)has an immediate requirement to upgrade 18 Demand Assigned Multiple Access (DAMA) Orderwire Channel Controller Trainer/Simulator (DOCCT/S) to the MIL-STD-188-183A configuration. Thirteen DOCCT/S are 2-channel systems and five are 4-channel systems. DOCCT/S is a ViaSat, INC proprietary software and hardware turnkey trainer/simulator for UHF satellite communications. DOCCT/S replicates Demand Assigned Multiple Access (DAMA) network control station and network terminal operations. Internal satellite simulation includes frequency translation, digital transponder band limiting and hard limiting, and variable digital propagation delay, doppler effects, and thermal noise. DOCCT/S architecture is based on ViaSat's RT-1828 and RT-1830 UHF SATCOM network terminals, with the addition of ViaSat proprietary hardware and software to emulate network control and communication over a UHF satellite transponder each set of five VME modules (consisting of an I/O module, DSP module, transmitter module, receiver module, and satellite simulator module, in a DOCCT/S terminal) provides a simulated UHF SATCOM channel. The DAMA Network Control System (NCS) that provides worldwide coverage for 5 kHz and 25 kHz DAMA for the U.S. Government was designed developed, built, certified, and fielded by ViaSat. DOCCT/S replicates NCS software so terminal login and communications service requests are handled with the MIL-STD 188-182A, -183, -183A, -181B required protocol. This synopsis does not constitute a Request for Proposals, and is not to be construed as a commitment by the Government to issue an order. Providers of requested information are asked to respond within 30 days of this announcement. Please provide name of firm, address, POC, phone/fax number, and email address. Provide responses to USSOCOM (Attn SOAL-K) 7701 Tampa Point Blvd, MacDill AFB, FL 33621, ATTN: E. J. More, Contracting Officer, [email protected]. E- mail responses are encouraged. ALL QUESTIONS AND COMMUNICATIONS MUST BE CONDUCTED VIA E-MAIL. TELEPHONE REQUESTS FOR INFORMATION AND QUESTIONS WILL NOT BE RESPONDED TO.
