A Low Earth Orbit Satellite-Orbit Extrapolation Method Based on Multi-Satellite Ephemeris Coordination and Multi-Stream Fractional Autoregressive Integrated Moving Average

Aerospace
The low Earth orbit (LEO) satellite internet network (LEO-SIN) has become a heated issue for the next generation of mobile communications, serving as a crucial means to achieve global wide-area broadband coverage and, especially, mobile phone directly to

Software Development of High-Precision Ephemerides of Solar System [PDF]

Journal of Astronomy and Space Sciences, 1995
We solved n-body problem about 9 plants, moon, and 4 minor planets with relativistic effect related to the basic equation of motion of the solar system. Perturbations including figure potential of the earth and the moon and solid earth tidal effect were ...

Planetary ephemerides approximation for radar astronomy [PDF]

The planetary ephemerides approximation for radar astronomy is discussed, and, in particular, the effect of this approximation on the performance of the programmable local oscillator (PLO) used in Goldstone Solar System Radar is presented. Four different

Determinations of Asteroid Masses Using Mutual Encounters Observed in the Legacy Survey of Space and Time

The Planetary Science Journal
Using published simulations of the 10 yr Legacy Survey of Space and Time (LSST), we forecast its ability to determine the masses of individual main-belt asteroids (MBAs) through precise astrometry of any pairs of the ≈1.2 million known MBAs undergoing ...

Revised Ephemerides of the Martian Satellites, Phobos and Deimos

The Astronomical Journal
We report on the new ephemerides (MAR099) for the satellites of Mars derived from a large set of ground-based and spacecraft astrometric measurements. Our integrated orbit fit yielded latest estimates for the Martian tidal parameter τ = k _2 / Q = 1.816 ±

Global Dynamics and Ephemerides

, 2012
When speaking of Gaia it is instructive to remember the first ESA mission dedicated to high precision astronometry HIPARRCOS launched in August 1989. HIPPARCOS can be considered as Gaia's precursor, indeed the observing strategy aspects are similar and both missions were designed specifically for high precision astronmetry. After three and a half years
