58 -- SATELLITE COMMUNICATIONS (SATCOM) NETWORK (GSN) SOL DAAB07- POC Clinton Christ, (908) 532-9727, x5865, SFAE-C3S-SC-TT. Ground Component Command Technical Control and Analysis Element (GCC- TCAE) Satellite Communications (SATCOM) Network (GSN): POC Clinton Christ, (908) 532-9728, x5865. Project Manager Satellite Communications, Ft. Monmouth NJ, seeks sources for a low-cost, lightweight, Commercial-Off-The-Shelf (COTS) GCC-TCAE SATCOM Network initially consisting of 24 spoke and two hub (primary and back-up) SATCOM terminals, operating over Ku-band satellites. The mission of the GSN is to provide improved connectivity between the Ground Component Command -Technical Control and Analysis Element (GCC-TCAE) and various tactical Military Intelligence (MI) forces, from both United States Forces Korea (USFK) and the Republic of Korea (ROK), so as to provide usable tactical SIGINT to ROK and US warfighters. The GSN will enable the spoke terminals to push unprocessed INTEL information to the hub and to pull post-processed information from the hub. Typical data record size is 30 Kbytes, the largest, a 9 Mbytes data file, is transmitted on a daily basis. An aggregate data rate of 64 Kbps is desired for each spoke terminal in the GSN. Daily message traffic received at Hub ranges from 50 phone calls & 50 data messages during armistice to an estimated 3000 phone calls and 3000 data messages during war. Quantified traffic statistics are not available. The traffic demands under wartime conditions will be random and not follow any tempo. Access to the data base is achieved through the PCs operating over a network which employs a X.25 protocol. It is envisioned that phone calls will come into a single point at the hub and be switched to various numbers within the hub. The present system employs a dedicated leased telephone line to maintain continuous communication so to facilitate modem and COMSEC synchronization between each spoke and the hub. All communications must be link-encrypted. The GSN hub terminal must interface with the KIV-7 at the Hub (the KIV-7 is located in a SCIF) and the SG-84 (functional identical to the KG-84A) at the spokes. Mission equipment will typically be 500 meters from the GSN spoke terminal, the COMSEC/terminal interface must drive the signal this distance. All spoke terminal equipment (including cables) shall be of a size and weight to allow for hand portage by no more than 5 people. No part of the broken down spoke terminal shall exceed a two man lift. Antenna sizing must be sensitive to both weight and the efficient use of limited satellite transponder power. Set-up and tear down time for the spoke terminal shall not exceed 30 minutes under benign environmental conditions. Spoke terminal will be installed and operated by U.S. and ROK military personnel. Installation will be simple and require no special tools. Overall operation of the GSN will be simple and user friendly. During War conditions, spoke terminals may need to be deployed/ redeployed daily. GSN spoke terminals will be deployed in tents and must meet wartime operational mission requirements under the environmental conditions typical of the Korean peninsula. Each spoke shall support the simultaneous operation of two telephones, a FAX machine, and computer-to-computer data/message exchange. Spoke installation sites lack proper grounding and frequently have heavy power fluctuations. Power supplies should be plug-in and play capable. Spoke terminal power supplies should be capable of auto-sensing for both voltage and frequency to permit world-wide operation. The required range of operation for voltage is 60-250 VAC and 50 to 60 Hz for frequency. The Hub Terminals will be deployed in an environmentally controlled setting. Each hub shall be capable of simultaneous communication with all four circuits from each of the 24 spokes. Hub equipment excluding antenna shall be packaged in such a way that it can be broken down within 4 hours into transportable cases not to exceed a three-man lift. If the proposed Hub antenna cannot easily be moved, a contingency antenna must be provided with each Hub. The tear down/set up time for redeployment of a Hub shall not exceed 4 hours. The contractor shall provide a means for passing network control between Hubs, not to exceed 4 hours. Although the description of the hub and spoke SATCOM terminals differ, it is desired but not required that these terminal elements share common components to the fullest possible extent. The Hubs will tie into the available commercial power (regulated, filtered and UPS'ed) and stand-by tactical power generating equipment currently located at the GCC-TCAE. The contractor will be responsible for providing In-Theatre Depot level maintenance. Unit or organizational maintenance will be limited to replacing frequently consumed LRUs, cleaning, dusting and protection from the elements. Contractor maintenance must respond to terminal outages within 4 hours during armistice. It is envisioned that contractor maintenance will be facilitated by the use of float LRUs. The contractor depot is responsible for all necessary tools, test equipment and maintaining the proper level of floats. The contractor shall provide the initial GSN training, at the time of initial fielding. The contractor shall be responsible for providing bi-lingual (English & Korean) instructors and technical support representatives. Sustainment training will be the responsibility of the government. A solicitation package (specifications, SOWs, etc.) is expected to be available June 96. It is currently envisioned that the ensuing selection criteria will be based primarily on equipment demonstration of bid samples and to a lesser degree proposal evaluation. The bid sample demonstration will occur late July 1996, with contract award expected for late August 96. The first deliveries and installations will begin mid-January 1997. The contract will be set for initial delivery of 2 hubs and 10 spokes, with yearly options for the remaining and additional spokes. Request all interested parties reply with a brief equipment description, operational characteristics, and your commercially available/catalog prices as appropriate or best price estimates which the Government can use for planning purposes only. Send replies to PM SATCOM, SFAE-C3S-SC-TT ATTN: Clinton Christ, Ft Monmouth, NJ 07703 by COB 19 March 1996. This is not a solicitation, this information will be used to determine the viability of a future solicitation. (0060)
