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

Displaced geostationary orbits using hybrid low-thrust propulsion [PDF]
In this paper, displaced geostationary orbits using hybrid low-thrust propulsion, a complementary combination of Solar Electric Propulsion (SEP) and solar sailing, are investigated to increase the capacity of the geostationary ring that is starting to ...

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

Mapping daily evapotranspiration at field to continental scales using geostationary and polar orbiting satellite imagery [PDF]
Thermal infrared (TIR) remote sensing of land-surface temperature (LST) provides valuable information about the sub-surface moisture status required for estimating evapotranspiration (ET) and detecting the onset and severity of drought.

Light levitated geostationary cylindrical orbits are feasible [PDF]
This paper discusses a new family of non-Keplerian orbits for solar sail spacecraft displaced above or below the Earth's equatorial plane. The work aims to prove the assertion in the literature that displaced geostationary orbits exist, possibly to ...

Disposal orbits for GEO spacecraft: A method for evaluating the orbit height distributions resulting from implementing IADC guidelines [PDF]
Geostationary orbit (GEO) is the most commercially valuable Earth orbit. The Inter-Agency Space Debris Coordination Committee (IADC) has produced guidelines to help protect this region from space debris.

Suppression of co-channel interference in NGSO constellation system with interference alignment
Aiming at the problem that in the current space, non-geostationary satellite orbit (NGSO) constellation systems were increasing day by day, there are more and more satellite networks nearby orbiting using the same frequency band, and the problem of co ...

Australia has different levels of exposure to tropical cyclones. Using historical records, this study investigates the spatial variability of tropical cyclone formation across the Southeast Indian–South Pacific basin, quantifies the exposure of different parts of Australia to tropical cyclone weather events, and examines decadal variability in cyclone ...
