Data received from a satellite require special handling before they can be used. Data from differennt instruments are sampled at different rates, multiplexed (combined) into a single bit-stream, and recorded or transmitted to a receiving station in a compact format.

Complex scientific visualizations are becoming standard parts of many educational experiences, both in and out of schools. We found that satellite visualizations used by ocean scientists were difficult for teachers, students, and museum visitors to understand.

After more than 25 years of operating meteorological satellites, the United States now maintains a ground data handling and distribution system that has incorporated many technologies developed during the period. Because this system represents a considerable investment, future upgrading and replacements must not only be carefully planned, but ...

Abstract : In this paper we provide a survey of the history, technology and economics of commercial satellite data communications. Technological and economic trends in satellite data communications are examined, and the differences between the satellite channel and terrestrial channels are emphasized.

Abstract Starting in the early 1970s, the decline in column ozone over much of the earth has received much attention. Satellite ozone data, with the advantage of global coverage, now play an important role in assessing long-term trends in ozone distributions.

Satellite-to-Satellite Data Transfer and Control.
1977Abstract : The LES-8 and -9 satellites are three-axis stabilized earth-orbit spacecraft which provide communications at UHF and K-band frequencies with the capability of simultaneously establishing and automatically maintaining a K-band (36-38 GHz) satellite-to-satellite data link. The inter-satellite data crosslink extends the earth coverage over that

Several multisensor simulator packages are being developed by different research groups across the world. Such simulator packages [e.g., COSP , CRTM, ECSIM, RTTO, ISSARS (under development), and SDSU (this article), among others] share overall aims, although some are targeted more on particular satellite programs or specific applications (for research ...

TDRS satellite application to LEO satellite data link
SPIE Proceedings, 2013With the development of space technologies, satellite-based data link is becoming more and more popular due to its wide coverage. However, it needs tens of LEO satellites, short for Low Earth Orbiting satellites, to cover the whole Earth in real time. Therefore it requires huge investment to fulfill such an engineering.

Rapid advancements in sensor technology have enabled satellites to generate a very large amount of data for a variety of applications, e.g., hyperspectral imagers and imaging Fourier transform spectrometers. These sensors acquire over hundreds to a few thousand spectral bands of images of a scene and generate a lot of data.
