//Hello fellow traveler of the interwebs.//\\
//If you've ended up here because of the articles posted at BBC, msnbc, or all the other news media fronts, you've arrived at the right place.//
//Here is where it's actually happening.//

//You might want to consider a quick stop-over at the [[project:hgg:faq|Frequently Asked Questions]] page before diving into the details of the project itself.//

===== Status =====
February 2013: The project is currently on a bit of a slow burner since part of the core team is taking a brief hiatus focusing on other shorter term ideas before re-focusing on HGG.
However, there's still people of the core team and others working on various aspects of the HGG project and you're more than welcome to participate at any time.
If you want to inquire about the current status, please drop a mail to the [[https://lists.shackspace.de/mailman/listinfo/constellation|constellation mailinglist]].

===== History =====
[[http://events.ccc.de/camp/2011/wiki/Call_for_Space_Program|As proposed]] on [[http://events.ccc.de/camp/2011/|CCCamp11]] we need our own infrastructure and space program.
HGG's aim is to develop a modular antenna grid for satellite communication.

**Vision:** The hacker community needs a fallback infrastructure in case of natural and economic disaster to stay connected.

**Mid term goal:** Design and build a modular terrestrial base-station for satellite communication.  Based on open-source hard- and software as well as open standards.

**Short term goal:** Gain insight into the nature, protocols and security features of satellite <> earth communication.
Build a working prototype of a modular receiver station with networking capabilities.
Provide interfaces to existing high performance computing platforms (GPU-based and similar systems).
