The AMS(R)S provides voice and data connectivity to users such as air traffic controllers, pilots and aircraft operators
The AMSS comprises satellites, aeronautical earth stations (AESs), ground earth stations (GESs) and associated ground facilities such as a network coordination center.
Existing satellite systems in operation for aeronautical communications
Computer-Aided Design and system analysis aim to find mathematical models that allow emulating the behaviour of components and facilities. The high competitiveness in industry, the little time available for product development and the high cost in terms of time and money of producing the initial prototypes means that the computer-aided design and analysis of products are taking on major importance.
A low earth orbit (LEO) satellite constellation consists of a set of satellites orbiting the Earth with high constant speed at a relatively low altitude (a few thousand kilometers) . Each satellite is equipped with a fixed number of antennas that allow it to communicate with ground transmitters/receivers and with other satellites. One of the major advantages of LEO satellites (as opposed to geostationary—GEO—satellites) is that they are closer to the Earth’s surface.
The purpose of this monograph is to formulate a quantitative and self-consistent theoretical
approach to wave–particle interactions occurring in space plasmas, and present
a logical development of the subject. In the Earth’s magnetosphere, Nature has given
us a plasma laboratory that is accessible to observations made by radio, magnetic and
electric instruments on the ground, and a great variety of instruments aboard rockets
and Earth-orbiting satellites. Spacecraft are making similar observations in the more
distant solar system.
In his presentation, Dr M. Bittner, Rapporteur on Satellite Measurements of Atmospheric
Consituents, first reviewed the GAW activities in Germany. These include supporting both Global
and Regional stations. Also Germany hosts the QA/SAC for Europe and Africa and has sponsored
GAW training courses at a number of locations in the country. He also explained the activities of
the German Aerospace Centre (DLR) and strongly endorsed the importance of coordinating
ground- and space-based atmospheric chemistry measurements.
