'EOS' is a fully functioning preemptive real time kernel originally developed for the Infineon XC167 microcontroller. Performance summary: A typical context switch will take about 100[Âµs] at 40[Mhz], when all tasks have a stack of 256 bytes.
Earth Observing System. A series of small- to intermediate-sized spacecraft that is the centerpiece of NASA's Mission to Planet Earth (MTPE). Planned for launch beginning in 1998, each of each of the EOS spacecraft will carry a suite of instruments designed to study global climate change. MTPE will use space-, aircraft-, and ground-based measurements to study our environment as an integrated system. Designing and implementing the MTPE is, of necessity, an international effort. The MTPE program involves the cooperation of the U.S., the European Space Agency (ESA), and the Japanese National Space Development Agency (NASDA). The MTPE program is part of the U.S. interagency effort, the Global Change Research Program (GCRP).
The Earth Observation Satellite. An effort to study the earth as a system while tracking long-term changes on a global scale. EOS, a mission of the National Aeronautics and Space Administration (NASA), will produce petabytes (1,000 terabytes) of satellite image data and also large-scale data sets (terabytes [1,000 gigabytes] a day) to be manipulated and analyzed.
Eos, Transactions, American Geophysical Union, a publication of the American Geophysical Union, is a weekly newspaper of geophysics that carries refereed articles on current research and on the relationship of geophysics to social and political questions, news, book reviews, AGU journal and meeting abstracts, meeting programs and reports, a comprehensive meetings calendar, and announcements of grants, fellowships, and employment opportunities. The weekly edition is published in tabloid form and is available electronically. A hardcover edition of Eos is published once each year and contains the articles, news, and editorials from the tabloid issues.
