WebApr 1, 2024 · Analysis of ephemeris prediction performance. The pseudo-range data we presented in Sec. 2 can be used to test ephemeris predictions. In particular, they provide 10-m level constraints on the geocentric distance to 67P and in turn on the geocentric range rate (10 m over two months correspond to about 2 μm/s). Thanks to the arcs covered by … WebIn this paper, we used simulation data to analyze the short-term prediction accuracy of the Martian ephemeris. The simulation results show that the accuracy of Mars position is expected to be better than 50 m for 180-day prediction, when 90-150 days’ range measurements are used to estimate the orbit of the Mars. In astronomy and celestial navigation, an ephemeris (pl. ephemerides; from Latin ephemeris 'diary', and Greek ἐφημερίς (ephemeris) 'diary, journal') is a book with tables that gives the trajectory of naturally occurring astronomical objects as well as artificial satellites in the sky, i.e., the position (and … See more • 1st millennium BC – Ephemerides in Babylonian astronomy. • 2nd century AD – the Almagest and the Handy Tables of Ptolemy • 8th century AD – the zīj of Ibrāhīm al-Fazārī See more • Almanac • American Ephemeris and Nautical Almanac • Ephemera • Ephemeris time See more For scientific uses, a modern planetary ephemeris comprises software that generates positions of planets and often of their satellites, asteroids, or comets, at virtually any time desired by the user.

WebThe orbit prediction algorithm utilises a suite of force models and a numerical integrator to produce an estimated ephemeris. The satellite orbit errors in the geocentric radial direction are 3 m (RMS) after 1 day, 9 m (RMS) after 3 days, and 21 m (RMS) after 7 days. WebThe computation of the SSB time is rather straightforward. Performing this step is required because the argument of the ephemeris itself is TDB time (ie, a clock referenced to the SSB). The two times are different because of the gravitational potential difference and doppler shifts between the earth and the SSB.
