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.

As an Agile software development program, TracSS will continue to field iterative upgrades and add new capabilities. 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.Outreach@noaa.gov.

OSC provides TraCSS “as is” and without any warranties, including, for example, that data and information from TraCSS will be error free or that access will be uninterrupted. The United States Government is immune from any suit arising from the provision or receipt of SSA data or information.
