D -- REPLACEMENT DEFENSE SATELLITE COMMUNICATIONS COMMUNICATIONS SYSTEM (DSCS) FREQUENCY DIVISION MULTIPLE ACCESS (FDMA) CONTROL SYSTEM SOL DAAB07-00-R-A254 POC Point of Contact: June E. Stone, Contract Specialist, 732-532-5489. Contracting Officer: John M. Adamitis, 732-532-3473 WEB: CECOM Acquisition Center's Business Opportunity Page, http://abop.monmouth.army.mil. E-MAIL: Click here to e-mail the POC, stonej1@mail1.monmouth.army.mil. The United States Army Communications-Electronics Command (CECOM) is seeking to modernize the control systems used for satellite communications. The Defense Satellite Communications System (DSCS) military communication satellites employ transponders that are each shared by dozens of users simultaneously via spread-spectrum, Time Division Multiple Access (TDMA), Frequency Hop (FH), and Frequency Division Multiple Access (FDMA) techniques. In order to provide quality service to all, the transmit parameters of all networks are carefully planned, closely monitored, and tightly controlled. These functions are carried out at DSCS Operations Centers (DSCSOCs) located around the world. Each DSCSOC contains the computers and equipment needed to control the networks carried on one or more satellites. The Common Network Planning Software (CNPS) will be used at each DSCSOC to determine the signal parameters of each network transmitter and plan the communications network configuration according to the locations andcapabilities of all network users and satellite transponders. The DSCS FDMA Control Subsystem (DFCS)is a Defense Information systems Agency (DISA) system that performs uplink power control, collects equipment performance data and communicates operator messages at fixed site, strategic earth terminals accessing DSCS satellites. The purpose of this control is to increase usability of available transponder power by reducing fixed margains on FDMA satellite link carriers. The DFCS uses an externally generated network plan to initially establish frequency, bandwidth, Bit Error Rate (BER), and transmit power level parameters for each carrier. The Government intends to replace the DFCS with a less manpower-intense system, taking advantage of technological improvements that are available, implementing improved control protocols that have been developed, message communications capabilities, and to provide a secure voice orderwire. Maintainability of the DFCS is threatened by diminishing vendor support for certain components; therefore, an open systems architecture with maximum use of Commercial-off-the-Shelf (COTS) components is required to eliminate vendor dependencies and take advantage of technology improvements in the commercial sector. The Replaceament DFCS (RDFCS) will provide the same performance and functionality as DFCS, provide additional functionality in some areas, and improved performance over the DFCS. The RDFCS will control the current fixed-site X-band FDMA earth terminals plus new fixed-site terminals, transportable tactical terminals, and commercial terminals, each of which could be designed to operate at some combination of one or more C, X, Ku and Ka bands. The DSCS Automatic Spectrum Analyzer (DASA) AN/FSQ-142, is another one of the subsystems used in the DSCSOCs, currently, to monitor the down-link signals of the controlled satellites. It compares its Signal-to-Noise Ratio (SNR) measurements to predicted values for each monitored down link and sets alarms as appropriate. The RDFCS will contain a fully integrated spectrum monitoring capability that will enhance and replace the spectrum monitoring capabilities of the DFCS as well as those spectrum monitoring functions that are part of the DSCS Automatic Spectrum Analyzer (DASA). This capability when specifically referenced in this acquisition is described as the Spectrum Monitoring Subsystem (SMS) of the RDFCS. In the process of integrating this capability within the RDFCS, the number of differing or unique Human-Computer Interfaces (HCIs) and the footprint of the control systems in the DSCSOC's will be reduced. The Government's acquisition approach is to award a basic contract with nine one year options. Award will be based on a best value approach using the principles of Cost As an Independent Variable (CAIV) and the Statement of Objectives (SOO) approach. The RDFCS basic contract will consist of a Firm Fixed Price (FFP) contract effort for the production, and testing of a limited number of strategic or fixed site RDFCS Network control Terminals (NCTs) and Network Terminals (NTs) which include SMS Threshold A requirements. Option 1 will include a FFP line item to integrate SMS Threshold B and Objective requirements that will become part of the production baseline if exercised. It is estimated that the RDFCS program will require 19 each NCTs, 15 Standalone NTs and 38 each Integrated NTs to include all associated spares and support. These items will be installed at 7 NCT sites and 32 NT sites. Furthermore, it is estimated that a range quantity of up to 100 Transportable Network Terminals (TNTs) to include all associated spares and support may be required. Time and Material requirements include: Deinstallation and Installation, Post Production Depot Support, Post Production Technical Services, Post Production Software Support and Transition of the Software Development Environment. It is estimated that a draft solicitation will be uploaded to the BOP on or about 29 Feb 00. See Note 26.
