Astrea Pre-solicitation Notice

The National Geospatial-Intelligence Agency (NGA) is providing this Pre-Solicitations Notice of its intent to conduct a Full and Open Competition for Astrea Requirement. NGA anticipates release of a solicitation / Request for Proposal (RFP) on or around 21 April 2026. The North American Industry Classification System (NAICS) code for this acquisition is 541715. BACKGROUND: The Astrea contract, a follow-on to the Spectrum contract, will produce a database that provides a system of data, parameters, and models that allow for the characterization of effective reflectivity, emissivity, and radiance as a function of arbitrary source, sensor, and target geometry, while estimating the errors associated with the computed values. It is contemplated that the solicitation will be posted to the CLASSIFIED Intelligence Community-Acquisition Research Center (IC-ARC) website https://acq.nro.ic.gov. To create a classified ARC account, you must first create an unclassified ARC account by visiting https://acq.westfields.net and clicking on the "Register" link at the top right of the page. Be sure to include your classified email address as you will not be able to access your classified account without it. Once you have finished the registration process on the unclassified system and validate your account by clicking the link you were sent via email, you will need to wait two business days for your classified ARC account to be automatically created. Once you have waited two business days, you will be able to log into your classified account using the same email and password you used on the unclassified system. This will bring you to a page where you can click a button to send yourself a verification email to the classified email account you listed when creating your unclassified account. This Pre-Solicitation Notice shall not be constructed as a commitment by the United States Government. Please be advised this is a Notice only. It does not obligate the Government to reimburse any cost associated with preparation and/ or submission of a response, nor does this Notice guarantee the Government will issue Solicitation/RFP or award your company a contract to provide these services.
