D -- CHALLENGE ATHENA GATEWAY SYSTEM SOL DCA200-98-R-0010 DUE 121897 POC Judith K. Titus, (618) 229-9539 The Defense Information Technology Contracting Organization (DITCO) intends to acquire commercial satellite gateway service to Government leased C-band transponders on commercial satellites worldwide. Satellite gateway services will be implemented using a combination of Contractor provided antennas, equipment, facilities, and personnel necessary to receive and transmit Radio Frequency (RF) signals in the C-band spectrum and convert that signal to and from Intermediate Frequencies (IF) for modulation/demodulation by Government-Furnished Equipment (GFE) installed in the commercial gateway. Circuits for digital connectivity between the commercial gateway and Government facilities will be provided by the Government. Satellites and transponders may change periodically. Current connnectivity is: Pacific Operating Region (POR) -- INTELSAT 702 or follow on at 177 degrees East longitude, global Transponder 85/85, full 36 MHz; West Coast Continental United States (West CONUS) -- Comstar D-4 at 76 degrees West longitude, hemi-transponder 2H, full 36 MHz, 9 degrees inclination, linearly polarized; East Coast Continental United States (East CONUS) -- Comstar D-4 at 76 degrees West longitude, hemi-transponder 3H, full 36 MHz, 9 degrees inclination, linearly polarized; Atlantic Operating Region (AOR) -- INTELSAT 601 or follow on at 332.5 degrees East longitude, global Transponder 38/38, full 36 MHz; Mediterranean Operating Region (MED) -- INTELSAT 707 or follow on at 359 degrees East longitude, East Hemi to West Hemi 21/11, partial 5 MHz, West Hemi to East Hemi 13A/23, partial 26 MHz. RFP DCA200-98-R-0010 will be released on or after 10 Nov 1997. All responsible sources may submit a proposal which shall be considered by DITCO. (0295)
