The Geostationary Applications Satellite
1988Berlin offers an in-depth look into all the engineering aspects of geostationary satellite design, construction, and launch. Geostationary satellites have opened new doors for the peaceful use of outer space. From vantage points 22,000 miles above the equator, they permit people anywhere on land, at sea, or in the air to communicate with each other ...

IEEE Communications Letters, 2018
Optical dense wavelength division multiplexing (DWDM) can provide multiple Tbit/s throughput in the future geostationary satellite communications. In this letter, the proof-of-concept demonstration of this technology under worst case atmospheric channel ...

Features of deorbiting geostationary satellites
Astronomical and Astrophysical TransactionsThe results of numerical simulation of the process of the disposal of a spacecraft from a quasi-geostationary orbit to a graveyard orbit with a height of about 280 km are presented. The calculations were carried out for a satellite with parameters very close to those of the Kazakh geostationary satellite Kazsat-2.

Orbits of Geostationary TV Satellites
International Astronomical Union Colloquium, 1997AbstractIn the frame of European cooperation among some stations (Brussels, Praha, Cagliari, Torino, Penc, Borowiec, Teddington, Metsahovi, Besançon and San Fernando) the method of time comparisons by a TV link has been used for orbit determination of the Eutelsat-F2 satellite.

Interferometric imaging of geostationary satellites
SPIE Proceedings, 2012Even the longest geosatellite, at 40 m, subtends only 0.2 arcsec (1 microradian). Determining structure and orientation with 10 cm resolution requires a 90 m telescope at visual wavelengths, or an interferometer. We de- scribe the application of optical interferometry to observations of complex extended targets such as geosatellites, and discuss ...

Elevation Angle Influence in Geostationary and Non-Geostationary Satellite System
2018 International Conference on Advanced Science and Engineering (ICOASE), 2018Earth stations elevation angle of antenna have to be established in order to communicate with satellites. In spite of crucial impairments in the uplink and down link of satellite communication between earth station and satellite such as noise, rain and atmospheric attenuations still earth station elevation angle is a key limiting factor to specify the ...

The Motion of Geostationary Satellite
2014There is no absolute stationary orbit for the geostationary satellite to reside in. Special attention we pay in this chapter to the geostationary satellite’s relative motion to the Earth’s rotation motion. We will illustrate the orbit motion of real geostationary satellite with the rotational Earth in inertial space.

2010 2nd International Conference on Information Technology Convergence and Services, 2010
In this paper, interference effect given from nongeostationary orbit link into geostationary orbit link is analyzed by BER performance. To analyze the interference effect with the angle between satellites, the angular separation is changed from 1° to 8°, and the number of the satellite is also changed from 1 to 4 for analyzing it. From the results, the

Time transfer via geostationary satellites
Proceedings of the IEEE, 1986Numerous experiments using geostationary satellites for two-way time transfer have demonstrated that this method can achieve subnanosecond precision and nanosecond accuracy. Efforts are now directed towards establishing operational networks.
