Performance of Angle of Arrival Detection Using MUSIC Algorithm in Inter-Satellite Link [PDF]
, 2018 An attitude of satellite is not always static, sometimes it moves randomly and the antenna pointing of satellite is harder to achieve line of sight communication to other satellite when it is outage by tumbling effect. In order to determine an appropriate direction of satellite antenna in inter-satellite link, this paper analyze estimation performance ...

Satellite Galaxies in the Illustris-1 Simulation: Poor Tracers of the Mass Distribution [PDF]
, 2018 Number density profiles are computed for the satellites of relatively isolated host galaxies in the Illustris-1 simulation. The mean total mass density of the hosts is well-fitted by an NFW profile. The number density profile for the complete satellite sample is inconsistent with NFW and, on scales < 0.5 r_200, the satellites do not trace the hosts ...

The orbital poles of Milky Way satellite galaxies: a rotationally supported disc-of-satellites [PDF]
, 2008 Available proper motion measurements of Milky Way (MW) satellite galaxies are used to calculate their orbital poles and projected uncertainties. These are compared to a set of recent cold dark-matter (CDM) simulations, tailored specifically to solve the MW satellite problem.

Satellite Optical Brightness [PDF]
AJ 166 59 (2023), 2023 The apparent brightness of satellites is calculated as a function of satellite position as seen by a ground-based observer in darkness. Both direct illumination of the satellite by the Sun as well as indirect illumination due to reflection from the Earth are included.

Satellite to Satellite Visibility [PDF]
The Open Astronomy Journal, 2012 In this paper, general analytical and computational technique for satellite-to-satellite visibility will be established. The developments are general in the sense that the visibility conditions can be used whatever the types of the satellite orbits may be. Numerical applications are also included.

Satellite RNAs and Satellite Viruses of Plants [PDF]
Viruses, 2009 The view that satellite RNAs (satRNAs) and satellite viruses are purely molecular parasites of their cognate helper viruses has changed. The molecular mechanisms underlying the synergistic and/or antagonistic interactions among satRNAs/satellite viruses, helper viruses, and host plants are beginning to be comprehended. This review aims to summarize the

Satellites of Satellites: The Case for Carina and Fornax [PDF]
Monthly Notices of the Royal Astronomical Society, 2019 Abstract We use the Auriga cosmological simulations of Milky Way (MW)-mass galaxies and their surroundings to study the satellite populations of dwarf galaxies in ΛCDM. As expected from prior work, the number of satellites above a fixed stellar mass is a strong function of the mass of the primary dwarf.

GNC Analysis and Robotic Systems Configuration of Collision-free Earth Observation Satellites (CfEOS) Constellations [PDF]
, 2021 The high number of objects in the LEO is a risk that collisions between sub-orbital or escape velocity objects with an orbiting object of satellites occur when two satellites collide while orbiting the earth. One of the approaches to avoid collisions is a robotic configuration of satellite constellations. Satellite constellations should not be confused
