J -- SOLE-SOURCE CALIBRATION, REFURBISHMENT, UPGRADING AND REPLACEMENT OF RADIOMETRIC EQUIPMENT SOL RFP5-63260-259 POC Lynne Hoppel, Contracting Officer, Phone (301)286-3035, Fax (301)286-1739, Email Lynne.C.Hoppel.1@gsfc.nasa.gov WEB: Click here for the latest information about this notice, http://nais.nasa.gov/EPS/GSFC/date.html#RFP5-63260-259. E-MAIL: Lynne Hoppel, Lynne.C.Hoppel.1@gsfc.nasa.gov. NASA/GSFC plans to issue a 5-year IDIQ contract on a sole-source basis to Satlantic, Inc., for calibration, refurbishment, upgrading and replacement of radiometric equipment used by the SeaWiFS Project pursuant to 10 U.S.C. 2304(c)(1) only one responsible source. All of the radiometric field instruments used by the SeaWiFS Project for validating the remote sensing data are manufacturered by Satlantic. The contract will allow for the improvement of instruments (taking existing components and combining them into more effective arrangements), the modification of existing equipment, and the production of spares to meet unanticipated problems associated with field (at sea) activities and the ground truth evaluation of the spaceborne SeaStar instrument. The following equipment will be part of the contract: 1) Upwelling Radiance Sensor: OCR-200 a compact seven channel analog radiance sensor capable of 16-bit performance. The saturation values for each channel can be adjusted to meet various requirements over a wide range while maintaining a 16-bit dynamic range. 2) Downwelling Irradiance Sensor: OCI-200 a compact 7 channel analog irradiance sensor capable of 16 bit performance. The saturation values for each channel can be adjusted to meet various requirements over a wide range while maintaining a 16-bit dynamic range. 3) Upwelling Radiance Sensor: OCR-1000 and 4) Downwelling Irradiance Sensor: OCI-1000 are essentially the same components as ICR-200 and OCI-200 respectively, maintaining a larger 24-bit dynamic range. 5) DATA-100 a 16 channel (expandable to 32 channel), 16-bit data acquisition system. 6-8)PRO DCU, DECK 100 and SAS DCU are deck control units that interface to the various Satlantic instrument configurations. These units provide power to and data from the instruments, as well as telemetry conversion links to a computer. 9-10) SeaWiFS Profiling Multichannel Radiometer (SPMR) (no model number) SeaWiFS Multichannel Surface Reference (SMSR) (no model number). The SPMR is designed specifically for use as a SeaWiFS validation system. Using DSP techniques and 24-bit A/D converters, the SPMR is capable of true 7 decade performance. Both systems can easily be deployed 50m or more from a vessel to avoid ship induced pertubations in the light field. 11) Model DIR-10, tilt and roll sensors, and a compass with the necessary data aquisition package. 12) Model MVDS is an in-air reference system consisting of an OCI-200 and a 16 bit DSP data acquisition system. 13) Model OCP 100 a sensor system consisting of OCR/I-200 sensor heads cabled to a DATA-100. With the appropriate adapter kits, the OCP-100 system can be reconfigured to build free-fall systems. 14) Model SQM produces a diffuse and uniform light field and is designed to be flush-mounted to radiance or irradiance sensors with a spectral range from 380-900 nm. Replacement of new devices for an old device listed herein is also expected. All of the government-owned radiometric field instruments used by Code 970.2 for validating the remote sensing data are manufacturered by Satlantic. In addition, two international groups GSFC collaborates with, the Plymouth Marine Laboratory (PML) and the Joint Research Center (JRC) located in England and Italy, respectively, use Satlantic equipment exclusively. GSFC has to be compatible with cooperating science teams to participate in the field activities to ensure compatibility with these groups and also to provide for equipment redundancy. Also, only Satlantic manufacturers a free-fall profiler. Competition is precluded because: 1) only Satlantic manufacturer's compatible instruments and a free-fall profiler; 2) Satlantic controls proprietary data essential to contract performance; and 3) only Satlantic has possession of the required capabilities essential for contract performance. However, companies that believe they can provide these services should fully identify their interest and capabilities within 15 days after publication of this synopsis on the NAIS or Commerce Business Daily. These capability statements will be used solely for the purpose of determining whether or not to conduct this contract award on a competitive basis. Responses received after 15 days or without the required information will be considered nonresponsive to the synopsis and will not be considered. A determination by the Government not to compete this proposed contract on a full and open basis, based upon responses to this notice, is solely within the discretion of the Government. Oral communications are not acceptable in response to this notice. See Note 22. Any referenced notes can be viewed at the following URL: http://genesis.gsfc.nasa.gov/nnotes.htm.
