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.

Business forecasting for communication satellite systems

Communications Satellite Systems Conference, 1966
Abstract This paper provides general guidelines for those interested in the general mechanics of projecting and forecasting the growth of a global satellite system but, in particular, for those interested in estimating the economic benefits accruing to participants in such a system.

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.

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.

A Communication Satellite System for Many Users

Communications Satellite Systems Conference, 1966
Abstract A demand is anticipated for communication satellite facilities by-many small users, each of which will have widely different antenna size and data-rate requirements. A system using time-division multiple-access modulation (TDMA satisfies this demand. The satellite contains a hard-limiting repeater of moderate bandwidth.

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 ...
