A -- AIR DEPLOYED, EXPENDABLE BATHYTHERMOGRAPH (AXBT) SOL DTCG32-98-Q-TPA010 DUE 120197 POC Susan E. Stevens 860-441-2665, Contracting Officer E-MAIL: Contracting Officer, Susan Stevens, sstevens@rdc.uscg.mil. The U.S. Coast Guard International Ice Patrol requires one to three integrated system to receive and process real-time sea temperature data from AXBT's (Air Deployed, expendable bathythermograph). System Requirements: Portability; system must be compact and easily transported by hand. Simplicity; operation with less than one hour operator training. Design/Construction: System must be of a high quality, durable design for use aboard military cargo aircraft. Calibration must be maintained within the following environmental specifications: Temperature: 0 to 120 degrees F, Relative Humidity: 5% to 95%. Case and hardware must be resistant to moderate amounts of shock. Spurious electromagnetic interference must be prevented from interfering with aircraft avionics systems. Operation: System must be capable of simultaneous reception and processing of three independent VHF channels. Receiver circuitry must be field programmable wihtin a frequency range of 162.5 mHz to 173.5 mHz. Receiver must provide audio output for monitoring received signal quality via headphone. Receiver must have sufficient sensitivity to detect and process AXBT signals from a maximum altitude of 10,000 feet and distance of at least 20 nm. Receiver will include DSP (disgital signal processor) filtering circuitry for enhancement of weak signal reception optimezed for AXBT signal modulation, bandwidth, and noise reduction. Unit will include a self-test function to verify the correct operation of all receiver channels and signal processor circuitry. Data Output: Processed AXBT data signals are to be output to standard PC-compatible computer port. PC Compatible computer hardware will be supplied by end user, and will be at least a Pentium 100 with 32 megs RAM and 420 meg hard drive, with color LCD display. Software: Contractor must provide signal processing software that will be capable of operating under the Microsoft Windows 95 or NT version 4.0 operating system. Software must provide the ability to display data of any single selected channel inreal time. Software must include the ability to perform raw data trace reduction with graphical comparison of raw and reduced/interpolated traces. Reduced traces must be stored in an ASCII format. Software must include the ability to produce JJXX messages from interpolated data. Software must include a simple means for editing JJXX content, and easily customized message boilerplate. It would be highly desirable for software to accept NEMA 0183 compatible GPS waypoints as input to determine drop coordinates. Software must not be dependant upon internal computer timings for calibration or accuracy, thus making the software computer independent. Power Requirements: Hardware must be capable of operation on standard line voltage of 110-125VAC, 50-60Hz. Until will include a rechargeable low voltage DC power source (gel cell preferred) with AC charger capable of operation for at least one continuous hour. This notice stands as the CBD Notice and Solicitation. There will be no solicitation package issued. Faxed responses can be sent to Susan Stevens, Contracting Officer at 860-441-2607. (0301)
