The Office of Space Commerce (OSC) has rolled out an iterative update to the Traffic Coordination System for Space (TraCSS) with updates for large satellite constellations, the office announced Tuesday. 

TraCSS has implemented Program Increment 1.2 for its beta users. OSC said this release introduces on-demand screening of operational ephemerides and enables bulk submission capabilities, which OSC said is “ideal for operators of large satellite constellations.” Beta user satellite operators can now submit ephemerides to TraCSS at any time and receive conjunction analysis results within two to five minutes. OSC also explained that constellations operators can now submit thousands of ephemerides at once via “bulk submissions.” 

OSC said the TraCSS team is preparing to expand user participation in advance of a full production release scheduled for early 2026.

“The implementation of Program Increment 1.2 is a major milestone for the TraCSS program and the evolving state-of-the-art in U.S. space situational awareness capabilities,” said Janice Starzyk, acting director of the Office of Space Commerce. “With on-demand conjunction analysis for satellite operators, we are advancing space safety.” 

TraCSS is part of a years-long effort for OSC to take over space situational awareness (SSA) services from the U.S. Department of Defense and to leverage data from operators, governments, commercial, academic, and international sources.
