BAA Process and Topic Call Publication:

The BIG-ST BAA is a general announcement of NGA’s research interest, including criteria for selecting proposals and soliciting the participation of all offerors capable of satisfying the Government’s needs.

The requests for abstracts and proposals are transmitted via Topic Calls that are published separately under the BIG-ST BAA General Solicitation at various times during the open period of the General Solicitation. Topic Calls will be published via updates to the BIG-ST BAA General Solicitation site on Sam.gov, Grants.gov, and/or the Classified IC-Acquisition Research Center (https://acq-ui.ace.proj.nro.ic.gov). If a Topic Call is Classified, interested parties must have an account to log into the Classified IC-ARC to see the notice, and all associated RFP documents. For additional support with account access, please contact the Classified ACE Help Desk at 855-4ACE.Interested parties should periodically check these websites for updates.
