The OTS Satellite In Orbit – Artist’s Impression

This is a sorry tale of how four years’ work was destroyed in 54 seconds. Some say that the number thirteen is unlucky and on 13th September 1977, exactly 35 years ago today, this proved to be the case for me and the whole team that developed the OTS satellite. Here’s how things played out.

The European Space Agency’s Orbital Test Satellite (OTS) was one of the very first geostationary, 3-axis-stabilised Ku-Band communications satellites. It was developed as a test bed for a host of new European technologies and transmission techniques aimed at bringing regional TV and trunk telephony services to Europe. It was the forerunner of the highly successful ECS satellites which were subsequently operated and managed by EUTELSAT.

I spent four years working on different aspects of the OTS satellite, the communications transmission design and on the ground segment earth stations. For any interested readers with a technical bent you can check out details on the EXPERIENCE and PUBLICATIONS pages of this site.

In March 1977 I took on the role of designing, planning and implementing the in-orbit testing (IOT) of OTS. This was to be carried out from Telespazio’s Fucino earth station complex in the mountains east of Rome, Italy, and you can check out the Fucino earth station complex with the interactive Google Map on my related blog post [Read more…]

50 Years of Satellite Communications

July 27, 2012 by Leave a Comment

It’s not often that I publish two blog posts in quick succession, but this is an exception. Only a couple of weeks ago on July 10th 2012 I posted “The Birth of Satellite Communications” on the anniversary of the launch of Telstar, the world’s first commercial communications satellite.
That blog post was subsequently published in the July 2012 MilsatMagazine article here.

Since then I have come across some other references and resources that I believe are really worth capturing and sharing. First, an excellent 12 minute video produced by the European Space Agency and entitled “50 Years via Satellite”. Below the ESA video are links to some things that The Smithsonian National Air & Space Museum have contributed. All these are worth watching.

The Smithsonian Institute hosted a commemorative event here.
The chair of their History Division, Paul Ceruzzi, produced a very good blog post here.

Many thanks to Isabel Lara (@isalara) at The Smithsonian for providing these two links.

Olympic Games 2012 – Powered by Satellites

July 26, 2012 by 5 Comments

Without satellites, the Olympics wouldn’t be what they are …

London 2012 Olympic Games Stadium

London 2012 Olympic Games Stadium

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.
