Modeling and Analysis of Battery Thermal Control in a Geostationary Satellite

open access: yesSakarya Üniversitesi Fen Bilimleri Enstitüsü Dergisi, 2022
Battery technology has been used for geostationary satellites since the first satellite sputnik-1 was launched in 1957. The majority of larger geostationary satellite’s lives range from 7 to 15 years. During the lifetime of satellites, the batteries used

SPECTRAL OBSERVATIONS OF GEOSTATIONARY SATELLITES

open access: yesEurasian Physical Technical Journal, 2022
One of the main tasks of the situational awareness system in near-Earth space is to determine the type and class of observed objects by analyzing its reflection spectra. This paper proposes a methodology and interpretation of the spectral observational data of geostationary orbit satellites obtained at the Tian

High-resolution retrieval of cloud microphysical properties and surface solar radiation using Himawari-8/AHI next-generation geostationary satellite

open access: yes, 2020
Optical properties of clouds and heavy aerosol retrieved from satellite measurements are the most important elements for calculating surface solar radiation (SSR). The Himawari-8/Advanced Himawari Imager (AHI) satellite measurements receive high spatial,

The zero gravity curve and surface and radii for geostationary and geosynchronous satellite orbits

open access: yesJournal of Geodetic Science, 2017
A geosynchronous satellite orbits the Earth along a constant longitude. A special case is the geostationary satellite that is located at a constant position above the equator.

A passive satellite deorbiting strategy for MEO using solar radiation pressure and the J2 effect [PDF]

open access: yes, 2011
The growing population of space debris poses a serious risk to the future of space flight. To effectively manage the increase of debris in orbit, end-of life disposal has become a key requirement for future missions.

Geocentric Spherical Surfaces Emulating the Geostationary Orbit at Any Latitude with Zenith Links

open access: yesFuture Internet, 2020
According to altitude, the orbits of satellites constellations can be divided into geostationary Earth orbit (GEO), medium Earth orbit (MEO), and low Earth orbit (LEO) constellations.
