Navigation Ephemeris Service is a space data service that publishes precise position and velocity data for mission planning for position, timing, and trajectory services. 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 Navigation Ephemeris Service when the navigation solution was updated, so the team could align navigation, communications, and safety analysis before the next mission decision point.”
