This paper describes the Telstar system and discusses the over-all system design. System considerations, the orbit selection and frequency allocation considerations are covered. A general description of the Telstar satellite and Andover, Maine, ground station provides background for companion articles in this series.

After having studied the Earth’s Moon in Chap. 8, we now look at the moons of the other planets of the solar system. A quick look at the two moons of Mars is followed by a detailed examination of the four Galilean satellites of Jupiter: Io, Europa, Ganymede and Callisto.

Recently, the interest in broadband satellite multimedia (BSM) systems has grown rapidly. Advancements in transmission technology have led to the availability of low-cost satellite earth terminals. The superior remote access capabilities of satellite networks are foreseen to provide broadband services to geographically diverse user groups.

Tracking of a satellite provides the most vital information about its position and its orbit in space. Tracking is very much essential not only during its launch for initial critical maneuvers but even after launch to maintain it in assigned slot in space.

In today's unpredictable and dynamic environment, flexibility is an important aspect in system design. Flexibility increases system capability and effectiveness, reduces long term cost, encourages innovation, and protects against uncertainty. It is often at odds with optimization.

Satellite Communication Systems
2004Satellite-based communication has become a major facet of the telecommunication industry for two major reasons. First, it provides a means of broadcasting information to a large number of people simultaneously. Thus, satellite communication systems are an important ingredient in the implementation of a global communication infrastructure.

Proceedings of the IEEE, 1978
This paper describes the measurement techniques employed to test the elements of a communications satellite system. Techniques for measuring the gain-to-noise-temperature ratio (G/T) of an earth station antenna are presented. The measurement of earth station polarization characteristics is discussed extensively in terms of the new requirement for ...

The PICPOT satellite antenna systems
2007 IEEE Antennas and Propagation Society International Symposium, 2007This communication deals with the design and development of the antenna systems, for the Spacecraft and for the Ground Station, of the PICPOT satellite [1], a pico-satellite developed at Politecnico di Torino mainly as a students project [2]. The redundancy of the project requires a double link in the lower UHF and at S band.
