Only a lucky few million people will actually attend the London 2012 Olympic Games, whereas billions of people all over the world will feel part of the event as a result of the immediacy of live television.

The following 4 minute video produced by the European Space Agency, a leading light in the development of satellite communications, gives an overview of how this is achieved:

In the coming days the Olympic Games will attract a worldwide audience and from wherever we are on the globe we’ll all be able to follow the events in London. This is a fantastic showcase for space technologies which are often unknown and taken for granted.

The evolution of space activity, and in particular, satellite telecommunications, has transformed the planet into a big stadium where everybody has a front seat. This video recalls the extraordinary progresses made in the relay of sports and the new tools now available for professionals and spectators around the world.

The Telstar Satellite

The Telstar Satellite

10th July 1962 marked the birth of satellite communications. Exactly 50 years ago today the Telstar satellite commenced its journey into space from Cape Canaveral and became the first ever active commercial communications satellite. It carried the first live trans-Atlantic TV broadcasts.

These days, satellite launches are commonplace and polar orbits, MEO orbits, Molniya orbits, Tundra orbits and the geostationary orbit are filled with communications satellites operating at frequency bands from UHF through L-Band, S-Band, C-Band, X-Band, Ku-Band, Ka-Band and above. As at 1st January 2012 there were 419 satellites operating in the geostationary orbit alone.

I’m not writing this as a “third party commentator”, but as someone who has been intimately involved with and has contributed to the development of satellite communications [Read more…]

ULA Launch of Boeing WGS-4 Satellite

ULA Launch of Boeing WGS-4 Satellite

Boeing has received the first on-orbit signals from the fourth Wideband Global SATCOM (WGS) satellite it is delivering to the U.S. Air Force. The signals indicate that WGS-4, the first in the Block II series, is healthy and ready to begin orbital manoeuvres and operational testing.
Further detailed information can be found on Boeing’s website here.

WGS-4 launched on a United Launch Alliance Delta IV vehicle on 19th January 2012 at 7:38 p.m. Eastern time from Cape Canaveral Air Force Station. Controllers confirmed initial contact with the spacecraft 58 minutes later at 8:36 p.m. Eastern time at a ground station in Dongara, Australia. Boeing’s Mission Control Centre in El Segundo, California confirmed that the satellite is functioning normally.

The dramatic launch video, photographs and further information can be found on ULA’s website here.

WGS-4 is an extremely advanced satellite operating at the established X-Band and the high frequency Ka-Band. It uses phased array, shaped beam, steerable spotbeams to provide coverage to support coalition forces [Read more…]
