Time and coordinate systems are two basic elements for navigation system. For a navigation system, the position and velocity of a spacecraft should be described in a special time and coordinate system. In addition, the establishment of orbit dynamics model and the generation of navigation measurement data often involve the calculation of celestial ephemeris. This chapter presents the description of time system, definitions, and transformation of reference coordinate systems, and ephemeris calculation for navigation celestial bodies.
