System study on Gigabit satellite communications

Space Communications, 1998
The objective of the Gigabit satellite is to provide the global high‐data‐rate communications network. The key technologies are the Ka‐band scanning sport beams, on‐board ATM switch, inter‐satellite laser link and the advanced beam control.

Satellite Communication Systems

2017
In satellite communication (Fig. 7.1), satellites are used to relay signals between ground stations. The signal is received from one ground station and re-transmits to one or more receiving ground stations elsewhere with the help of satellite.

Asia-pacific satellite communications system

1st International Symposium onWireless Communication Systems, 2004., 2005
The authors propose herein a large-capacity satellite intranet and dedicated evolutionary communications services for business users, which offer high availability, low cost and security, by using a network that is separate from the Internet. Ka band spot beams enable high-speed transmission of 1.2 Gbps per transponder and 90 Gbps per satellite.

Doubling the capacity of a communications satellite system

IEEE Communications Magazine, 1997
Two one-way channels are normally used in digital two-way voice communication. Each channel is in effect-used only one half the time. A recent discovery of ours recognized that any one-way channel within a satellite spot-beam can be accessed by anyone in the footprint of the beam.

System Considerations for European Communication Satellites

IEEE Transactions on Communications, 1973
A regional communication satellite system is being planned for Europe to satisfy the future needs of the European Conference of Post and Telecommunication Administration (CEPT) and the European Broadcasting Union (EBU). A model of the mission for the satellite system, based on the estimated future traffic requirements of the potential customers, has ...

Global satellite communications technology and systems

Space Communications, 2000
This special issue of Space Communications contains nine papers derived from a study, ‘Global satellite communications technology and systems’, sponsored by NASA and the NSF. The purpose of this study was to compare the position of the US in commercial satellite communications technology, research, development and markets with that of the rest of the ...

Scheduling and control of satellite communication systems

Communications Satellite Systems Conference, 1966
Abstract This paper examines important parameters of the satellite communication system control problem and defines the scheduling function for satellite communication control systems. Scheduling is considered as the function of matching communication requirements to system assets over a particular period of time.

The Norwegian domestic communication satellite system

7th Communications Satellite Systems Conference, 1977
Publisher Summary This chapter focuses on the Norwegian domestic communication satellite system. Radio communication for offshore oil rigs has for years been carried out by conventional medium frequency (MP) radiotelephony, usually on a one-channel simplex basis. This has been the method used in the Mexican Gulf and other well-known areas, and it was

Reliability of Commercial Communications Satellite Systems

IEEE Journal on Selected Areas in Communications, 1986
Over the past 20 years, commercial communications satellite systems have developed into effective and reliable global, regional, maritime, and domestic communications services. These systems provide telephone, telegraph, television, data, and facsimile transmission and reception.
