University of Tartu SeaBird & DALE System Services

The NASA Shared Services Center (NSSC) is procuring specialized radiometric calibration and characterization services from the University of Tartu. This requirement supports field radiometers at the NASA Goddard Space Flight Center (GSFC) used for the Plankton, Aerosol, Cloud, ocean Ecosystem (PACE) Mission. The agency intends to award a sole-source contract under FAR 12.102(a), as the University of Tartu is the only provider capable of performing the necessary services for SeaBird and DALEC systems. The scope includes technical characterization across specific wavelength ranges and environmental conditions to ensure instrument accuracy. Performance will take place at GSFC. While the agency intends to proceed on a sole-source basis, capability statements and qualifications submitted by June 8, 2026, will be evaluated to determine if a competitive procurement is warranted. The solicitation includes a Statement of Work (SOW) detailing technical specifications, performance standards, and a milestone-based invoicing structure.
