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, free of direct user fees.

As an Agile software development program, TracSS will continue to field iterative upgrades, add new capabilities, and migrate users from the Department of Defense. The initial version, released September 2024, distributes TraCSS-produced conjunction data messages (CDMs) to a beta set of users via the Space-Track.org interface. As the TraCSS user interface matures, OSC will migrate users to TraCSS.gov.

Stakeholders interested in engaging with TraCSS may reach out to TraCSS.Commerce@noaa.gov.

Stakeholders interested in offering the TraCSS team novel technology concepts, industry capability statements, and/or integration ideas may contact our new “TraCSS Innovation” email account. More information is available on the TraCSS Frequently Asked Questions webpage,
