ESA - Types of orbits - European Space Agency
2020年3月30日 · Satellites in geostationary orbit (GEO) fly above Earth’s equator, moving from west to east, exactly matching Earth’s rotation: taking 23 hours 56 minutes and 4 seconds to …
Geostationary orbit - Wikipedia
A geostationary orbit, also referred to as a geosynchronous equatorial orbit [a] (GEO), is a circular geosynchronous orbit 35,786 km (22,236 mi) in altitude above Earth's equator, 42,164 km …
Basics of the Geostationary Orbit - CelesTrak
Orbits with non-zero eccentricity (i.e., elliptical rather than circular orbits) will result in drifts east and west as the satellite goes faster or slower at various points in its orbit. Combinations of …
SBE 24 GeoSat Pt2
The following figure illustrates the geostationary orbit. Note that individual satellites within the orbit are identified by longitudinal position east or west of the Prime Meridian. All geostationary …
Geostationary Operational Environmental Satellite (GOES) East and West
2018年1月31日 · NOAA maintains a two-satellite Geostationary Operational Environmental Satellite (GOES) constellation to watch over the Western Hemisphere. The satellites circle the …
Orbital station-keeping - Wikipedia
The East-West control is the control of the orbital period and the eccentricity vector performed by making thruster burns tangential to the orbit. These burns are then designed to keep the …
Geostationary Orbit | West East Space
2020年2月19日 · Geostationary satellites are launched via a temporary orbit, and placed in a slot above a particular point on the Earth’s surface. The orbit requires some stationkeeping to keep …
ESA - Spacecraft orbits - European Space Agency
Geostationary satellites are those orbiting above the equator in a circular orbit – they appear to ‘hover’ in the sky over the same spot on the ground. Geosynchronous satellites are not …
GOES Overview - National Oceanic and Atmospheric Administration
Geostationary satellites circle the Earth in geosynchronous orbit, which means they orbit the Earth’s equatorial plane at a speed matching the Earth’s rotation. This allows them to stay in a …
The east‐west effect in solar proton flux measurements in geostationary ...
2010年4月14日 · The gyrocenters of the fluxes observed looking westward (eastward) lie outside (inside) geostationary orbit. Due to this “east-west effect,” eastward observations of 4.2–82 …
