Deep Space Ephemeris Service

机器辅助翻译草稿 (Chinese) for "Deep Space Ephemeris Service": Deep Space Ephemeris Service is a space data service that publishes precise position and velocity data for mission planning for long-delay spacecraft operations beyond Earth orbit. 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.

“示例草稿: The mission team used Deep Space Ephemeris Service when the probe passed behind a planetary body, so the team could align navigation, communications, and safety analysis before the next mission decision point.”
