58 -- 915 MHZ P4 POD DATA LINK TRANSPONDER SYSTEM SOL F08651-97-R-0006 DUE 052897 POC Chuck McFarlin, (904) 882 -- 4092, Contract Specialist; Contracting Officer, Lonnie L. Oswalt The Air Force Development Test Center (AFDTC), intends to solicit and negotiate, with only one source, IAW FAR 6.302-1 (a) (2) (ii), Micro Systems, Inc., 65 Hill Avenue, Fort Walton Beach, Florida 32548, (904) 244-2332 and IAW with Federal Acquisition Regulation (FAR) Part 12, Commercial Acquisitions, for thirteen (13) airborne Data Link Transponders (DLT) Time Space Position Information (TSPI) and multilateration systems, Model #210, Part # AY95210 designed to operate on Gulf Range Drone Control Upgrade System (GRDCUS) range at Tyndall AFB, Florida. The system must be able to be mounted on a standard P4B Airborne Pod (less than 5"). It must also operate on 28 VDC + 4 or -- 6 VDC at a minimum current of 8 amps continuously. The system must correctly receive GRDCUS and GRDCS II variable length formatted messages at 915 MHz and -93 dBm to -2dBm. The DLT must respond to broadcast messages and also to individually addressed messages at 10 messages per second. The DLT must properly decode RTCM104 GPS correction messages and discrete commands. The DLT must respond to the individually addressed messages within precise time determined by response delay bits in the received message. The response by DLT must include GPS receiver data and discrete and digitized analog signals. The specific GPS data included in the transmitted message varies depending on message format group bits in the received message. 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 pseudo random 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 output 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 to provide a 0.99 or better probability of correct 256-bit message detection at RF signal input levels of -93 dBm and provide a 0.999 or better probability of message detection at a RF signal input level of -86 dBm to -2 dBm. The transponder must be capable of accepting external GPS TSPI (RS-232 & RS-422), four discrete and four analog inputs. Delivery is 120 days ARO. Replies to this synopsis should be provided to AFDTC/PKOS, 205 West D Avenue, Suite 541, Eglin AFB, FL 32542-6862. Firms are requested to submit information regarding their capabilities (i.e., literature, catalogs, brochures, etc.) to furnish supplies that comply with the requirements of the government. (No contract award will be made on the basis of bids/proposals received in response to this synopsis.) Firms responding to this synopsis should reference # F08651-97-R-0006 and indicate whether they are or are not a small or small disadvantaged business concern as defined in the Federal Acquisition Regulation (FAR) 52.219-1. The Air Force reserves the right to consider a small business set-aside based on responses hereto. Requests for copies of this solicitation must be in writing; or FAX, (904) 882-9442. Telephone requests will not be honored. See note 22.***** (0085)
