Аннотация

Planetary satellite’s ephemerides are valuable for spacecraft mission planing. Moreover, precise numerical theories of the natural satellites motion make it possible to improve the precision of their central planet’s ephemeris using the positional observations of their satellites. This paper describes the numerical theories of the Neptune’s satellites — Triton, Nereid and Proteus constructed using the modern CCD ground-based observations as well as space-based observations from the Voyager 2 flyby mission.
