58 -- AIRBORNE DATALINK TRANSPONDER TIME SPACE POSITION/MULTILATERATION SYSTEMS SOL F08651-95-R-0170 DUE 072895 POC Contact Todd Cook, (904) 882-9254, Contact Specialist; Contracting Officer, Bonnie Fitch. The Air Force Development Test Center (AFDTC) intends to acquire competitive, three airborne data link transponder Time Space Position Information (TSPI) and Multilateration systems designed to operate on the Gulf Range Drone Control Upgrade (GRDCUS) range Tyndall AFB FL. The system must be able to be mounted on a standard instrumentation tray which is designed to fit into the standard P4B airborne pod (less than 5'' dia.). The system must operate on 28 VDC +4 or -6 VDC at a maximum current of 8 amps. The system must be capable of detecting and accepting bi-phase modulated signals, produce digital data and demultiplex and decode data. The transponder shall use three specific pseudorandom chip codes, the sync is 127 bits long, Code A and Code B 31 bits long each. The center frequency of the receiver/transmitter shall be 915 MHz, 3 dB bandwidth of 30 MHz. The transponder shall have a minimum power out of +53 dBm with a duty cycle of 2.0 percent minimum indefinitely (a 2 millisecond transmission at a 10 Hz rate). The transponder shall use matched filters for detection of the Sync, A, and B codes. The receiver center frequency shall not vary by more than +10 ppm over the operating temperature range. The receiver sensitivity shall be provide a 0.99 or better probability of correct 256-bit message detection at RF signal input levels of -93 dBm to -2 dBm. The system must be capable of accepting external GPS TSPI (RS-232 and RS422), four discrete, and four analog inputs. In accordance with DOD Directive 4650.1, Management and Use of the Radio Frequency Spectrum, and DOD Federal Acquisition Regulation (DFAR) 252.235-7003, Frequency Authorization, JF/12 (frequency allocation) is required. Required delivery date is nine months ARO. Technical questions may be directed to James White, (904) 882-3619. Replies to this synopsis should be provided to AFDTC/PKOS, 205 W.
