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

open access: yesJournal 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 ...

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

open access: yesAerospace
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

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

open access: yesThe 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

open access: yesThe 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 ±

Graphics Processing Unit Resource Optimization for Orbital Alt-Azimuth Targeting Calibration in Alternative Laser Transmission Energetic Infrastructures

open access: yesTechnologies
Recent climate events have highlighted an increasing need for developing sustainable energetic infrastructures. Mainly, the evolution of existing industrial domains toward sustainability would involve major changes in energy management. As a consequence,
