This file provides IMCCE ephemeris "NOE-7-2013-MAIN" of the five main Uranian moons (Ariel, Umbriel, Titania, Oberon and Miranda).
Time coverage: 2395662.d0 (31/12/1846, 12H00) - 2504019.5 (03/09/2143, 00H00)
Polynomial degree: 20
The accuracy of Chebychev representations is better than 60 m (position) and 9.d-6 km/day (velocity) for all moons.
Expected external accuracy of these ephemerides highly depends on the moon and time considered.
Over the whole period available, an accuracy of about 5,000 km for the four outermost moons is expected. 10,000 km is more likely for Miranda.
An accuracy of few hundreds of kilometers is expected over the modern period (1980-2020).
