Traffic Coordination System for Space (TraCSS)
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,
The TraCSS authorized user SMS opt-in form may be downloaded here (.DOC).

OSC Announces Awardees of the Commercial COLA Gap Pathfinder
On June 11, 2025, the NOAA Office of Space Commerce announced the selection of awardees for the Traffic Coordination System for Space (TraCSS) program’s Commercial Collision Avoidance (COLA) Gap Pathfinder effort. Together, these awards amount to a total of $10.1M.
The “COLA gap” represents a critical challenge in space situational awareness (SSA): the period immediately after launch when traffic coordination services have uncertain or incomplete positional data on newly deployed satellites.
Through this pathfinder, the Office of Space Commerce sought innovative commercial approaches to address this operational blind spot. After evaluating a strong pool of proposals from across the SSA industry, the program has awarded contracts to a select group of vendors whose collective capabilities show considerable potential to close the COLA gap and improve safety during the earliest phases of satellite deployment.
