University of Tartu SeaBird & DALE System Services

NASA's Shared Services Center seeks University of Tartu SeaBird & DALE System Services for radiometric calibration and characterization of field radiometers supporting the PACE Mission, with capabilities statements due June 8, 2026. This is a sole source procurement under FAR 12.102(a); University of Tartu, Ulikooli 18, Tartu, Estonia, has been determined the sole provider. The Government will evaluate submitted capabilities and qualifications solely to determine whether to conduct this procurement competitively; a decision not to compete remains solely within Government discretion.

Place of performance is NASA Goddard Space Flight Center, 8800 Greenbelt Road, Greenbelt, Maryland 20771. The Statement of Work specifies six line items: DALEC System Calibration and Characterization Hardware Service, including absolute radiometric calibration from 350 nm to 900 nm at each pixel central wavelength (ISO 17025 accredited), angular response measurements from −90 to +90 degrees at 5-degree intervals across two azimuthal planes, polarization sensitivity testing from 0 to 360 degrees at 15-degree intervals for wavelengths 350 nm to 950 nm, thermal characterization at five temperature points from +5°C to +40°C, and straylight distribution function analysis; and five separate SeaBird/TriOS Sensors Hardware Services covering absolute radiometric calibration, angular response, polarization sensitivity, thermal characterization, and straylight distribution function. Period of performance is contingent upon NASA providing a shipping schedule on an as-required basis, with payment in four equal installments on August 31, 2026; December 31, 2026; March 31, 2027; and upon conclusion of calibration services. NAICS code is 611310, Colleges, Universities, and Professional Schools. Contact: Kacey Hickman, Procurement Specialist, Kacey.l.hickman@nasa.gov.
