Cleaning up a Hacked Website

Hacked

I’ve been hacked!

Hackers attack websites for a variety of purposes. Apart from defacement hacks more and more sites are becoming targets for criminals attempting to steal data – passwords, bank account details etc. There are numerous articles which describe such attacks, and that type of hack requires immediate specialist intervention and assistance. While this article here deals specifically with defacement hacks, the resources recommended here are equally applicable to all website hacking situations.

I hope that readers haven’t had the following experience. Here’s a typical scenario: [Read more…]

One of the first satellites designed to provide space-based digital radio service to consumers in the United States and Canada was donated by SiriusXM Radio and Space Systems/Loral to the Smithsonian. The Sirius FM-4 broadcasting satellite was built as a flight-ready back-up for a constellation of three satellites developed by SiriusXM and manufactured by Space Systems/Loral. The FM-4 satellite will be on display in the James S. McDonnell Space Hangar of the National Air and Space Museum’s Steven F. Udvar-Hazy Center.

“The availability of a flight unit like Sirius FM-4, which was never launched, is extremely rare and will be a significant addition to the museum’s collection,” said Martin Collins, space history curator. [Read more…]

Loss of the OTS 1 Satellite

OTS In Orbit - Artist's Impression

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…]
