A turnkey trainer/simulator for UHF satellite communications, DOCCT/S has the flexibility to address an entire range of UHF SatCom equipment training, integration, and mission rehearsal requirements.
DOCCT/S replicates Demand Assigned Multiple Access (DAMA) network control station and network terminal operations. Internal satellite simulation includes frequency translation, digital transponder bandlimiting and hard limiting, and variable digital propagation delay, doppler effects, and thermal noise. With DOCCT/S, you can develop, integrate, and train on UHF satellite communication equipment without the expense and time constraints associated with accessing live satellite channels.
The DOCCT/S architecture is based on ViaSat's RT-1828 and RT-1830 UHF SatCom network terminals, with the addition of 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 in the laptop PC so terminal login and communications service requests are handled with the MIL-STD required protocol. DOCCT/S also includes DAMA and NCS tutorials and preset database parameters to enable you to quickly understand and begin using the system.
It’s easy to configure DOCCT/S to meet the objectives of your project or program. DOCCT/S may include a single channel or multi-channel terminal to simulate up to four UHF SatCom channels that may include encrypted orderwire with an optional orderwire encryption board (OEB). Up to four user network terminals may be connected directly at UHF to the DOCCT/S Multiport UHF Interface Drawer (MUID). DOCCT/S may also be configured for local RF operation enabling up to 2000 additional user network terminals to participate in LOS UHF SatCom via antenna at ranges up to 12 miles. Up to four user baseband I/O devices per simulated channel may also be connected to DOCCT/S so that it may also operate as a network terminal.
