Mission Control Ephemeris Service

Mission Control Ephemeris Service is a space data service that publishes precise position and velocity data for mission planning for flight control room coordination. It uses orbit determination, time standards, and versioned trajectory products so teams can align navigation, communications, and safety analysis while keeping evidence, reliability, and public-safe operational boundaries clear.

“The mission team used Mission Control Ephemeris Service when the operations console detected a constraint, so the team could align navigation, communications, and safety analysis before the next mission decision point.”
