On the Use of Snoop with Geostationary Satellite Links

Third International Conference on Information Technology and Applications (ICITA'05), 2005
The performance of TCP decreases significantly when used over networks that exhibit a high bit error rate, as TCP has insufficient information to distinguish between loss that is due to corruption and that which is due to congestion. As a result, all loss is assumed to be congestion based, causing TCP to invoke its congestion control algorithms, even ...

Atmospheric soundings from a geostationary satellite

Applied Optics, 1983
The accuracy of the soundings from a geostationary platform with the visible infrared spin-scan radiometer atmospheric sounder (VAS) on GOES-5 is evaluated. It is shown that the VAS radiances for the case under investigation are consistent with those obtained by the polar orbiting high resolution infrared radiation sounders.

The earth location of geostationary satellite imagery

Pattern Recognition, 1970
Abstract Spin scan cloud pictures from NASA's Applications Technology Satellites are being computer processed as an operational experiment. Details of this near-real-time image manipulating activity are described. Processing involves the treatment of horizon and landmark features in support of the photogrammetric aspects and the subsequent ...

XCP in a geostationary satellite context

2008 IEEE International Workshop on Satellite and Space Communications, 2008
This paper tackles the use of the XCP transport protocol in a satellite context. XCP aims mainly at avoiding congestion. However, in GEO satellite access network, XCP is also expected to offer fairness between data flows, a better bandwidth use and a quite stationary throughput per flow. Then, the two main points of this work are to propose a satellite

Time transfer via geostationary satellites

Proceedings of the IEEE, 1986
Numerous 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.

Performance of Satellite Gateway over Geostationary Satellite Links

MILCOM 2013 - 2013 IEEE Military Communications Conference, 2013
A significant amount of today's Internet traffic, including World Wide Web (WWW), file transfer, e-mail and remote access traffic, is carried by the Transmission Control Protocol (TCP) transport protocol. Geostationary satellite links have a number of features that may degrade the performance of the TCP over them.

The Motion of Geostationary Satellite

2014
There 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.

Geostationary satellites for small jobs

IEEE Spectrum, 2020
Atypical geostationary satellite is as big as a van, as heavy as a hippopotamus, and as long-lived as a horse. These parameters shorten the list of companies and countries that can afford to build and operate the things.

On evolution of geostationary satellite orbits

Advances in Space Research, 1997
Abstract Among more than 360 known uncontrolled geostationary satellites there are only 16 objects, that change their regime of motion, or are close to this situation. The precision of the calculation of their orbital evolution depends on the accuracy of geopotential model.

Geostationary Satellite Navigation Systems

IEEE Transactions on Aerospace and Electronic Systems, 1987
The concept of position determination using geostationary satellites as an alternative to the global positioning system (GPS) is studied. The advantage of a geostationary system is that only three, or at most four, satellites are required to cover the continental United States.
