Cracking the secret codes of Europe's Galileo satellite

Filed under
Sci/Tech

The navigational satellite, GIOVE-A (Galileo In-Orbit Validation Element-A), is a prototype for 30 satellites that by 2010 will compose Galileo, a $4 billion joint venture of the European Union, European Space Agency and private investors. Galileo is Europe's answer to the United States' GPS.

Because GPS satellites, which were put into orbit by the Department of Defense, are funded by U.S. taxpayers, the signal is free -- consumers need only purchase a receiver. Galileo, on the other hand, must make money to reimburse its investors -- presumably by charging a fee for PRN codes. Because Galileo and GPS will share frequency bandwidths, Europe and the United States signed an agreement whereby some of Galileo's PRN codes must be "open source." Nevertheless, after broadcasting its first signals on Jan. 12, 2006, none of GIOVE-A's codes had been made public.

Why the Open Source Stars Must Align

Open source projects like OpenStack, Docker, OPNFV and OpenDaylight are more supported and better funded than ever before. They mark a broader trend of large, active and well-resourced open source projects that are among the leaders in Big Data, cloud computing, operating systems and development practices. Open source has come a long way in 30 years – and its success marks a new era for the overall OSS community. But success does not come without potential pitfalls. One of the greatest obstacles to project success isn’t the proprietary competition – it’s the lack of communication between large open source projects like OpenStack and Docker. Read more

Myth Busting the Open-Source Cloud Part 1

On the contrary, open-source cloud computing products are designed from the outset with security in mind. For example, there are features such as identity management to monitor who has access to content, and data encryption to safeguard information while it’s at rest or in transit. Furthermore, open-source cloud software is peer-reviewed by community participants, leading to continuous improvements in the quality of security features and mechanisms. This community also monitors and rapidly discloses vulnerabilities and issues, and provides security updates to address them. Read more

What does an adult look like in an open source community?

You're no longer "just an adult." You're now trusted and looked to for opinions on how the community should grow. You're a community elder. You embody the history. You keep the history. You work together with other adults and elders to guide and make the community stronger. And to a certain extent, the community once again looks after you, just as it did in the first phase. Read more
