Traffic Coordination System for Space
NOAA’s Office of Space Commerce (OSC) is developing the Traffic Coordination System for Space (TraCSS) to provide basic space situational awareness (SSA) data and services to civil and private space operators in support of spaceflight safety.
TraCSS is being developed to implement President Trump’s direction in Space Policy Directive 3 for the Department of Commerce to provide space operators with space traffic safety data and services.
As of May 2026, the Traffic Coordination System for Space is accepting satellite owner/operator registrations directly through the TraCSS webpage. To access the registration page (which includes step-by-step instructions), visit this link (TraCSS.gov)
Stakeholders interested in engaging with
TraCSS may reach out to TraCSS.Outreach@noaa.gov.
