Satellite Communications Technology

In this educative section you will find details to aspects of satellite communications technology and answers to questions about how satellite communications can benefit to your business.

Satellite Network Architectures

Point-to-point, one-way and two-way links between two earth stations are the simplest link architecture. More complex communications requirements need sophisticated network topologies, such as point-to-multipoint, star and mesh .

Satellite Transmission Standards

Today''s satellite transmissions are governed as well by proprietary technologies and public standards, such as DVB. Legacy VSAT players have reacted to market demand and either offer or plan to offer a standards-based satellite platform.

VSAT - Very Small Aperture Terminal

VSAT describes a small terminal that can be used for one-way and/or interactive communications via satellite. VSAT networks offer value-added satellite-based services capable of supporting the Internet, data, video, LAN, voice/fax communications. Their advantages include ubiquity, quick deployment capability, and cost-control. 

Satellite Transponder

A satellite transponder is an electronic circuit on a satellite that receives, modulates, amplifies and re-transmits an uplinked signal. Todays satellite can carry up to 30 transponders.

Satellite Capacity

The communications needs of the whole world can be served by a network of three geostationary satellites. Today, there are hundreds of satellites in orbit. Due to market exchanges for surplus capacity, it is possible to procure the needed satellite resources at discounted prices.

Satellite Teleports

Teleports are facilities located throughout the world, built for the purpose of maintaining high quality communications with orbiting satellites.  A teleport consists of a number of technical systems for data transmission and reception via a satellite connection.
