Hack a Day
[David Prutchi] has an FTA (free-to-air) satellite dish. This means he can tune and watch freely available satellite television feeds. But this sounds much better than it actually is. There isn’t much that’s broadcasted unecrypted from satellites with the exception of a collection of religious channels. But he still uses the dish by using the FTA [...]

satellite Event:
Chaos Communication Camp 2011 Abstract: In this lecture, I'll cover some satellite communication basics like pros and cons of different orbits, the characteristics of a satellite communications link and the difficulties regarding noise and attenuation when handling high frequency satellite communication systems. After a brief introduction to the history and development of satellites in general, we'll talk about different orbits and their characteristics regarding space conditions. After that, we'll have a look at a typical satellite communications link including channel characteristics, communications equipment and frequency considerations, before moving on to access techniques. If there's still time, there might be a short part about satellite navigation, too. And yes, to meet our need for pretty pictures, thematically related postage stamps (partly from a private collection) will be used to illustrate the topic.

Hack a Day
[Nate] over at Sparkfun put up a great tutorial for using the SPOT personal satellite communicator with just about any microcontroller. These personal satellite transmitters were originally intended to pair with the bluetooth module of a smart phone, allowing you to send a short 41-character message from anywhere in the world. Now, you can use these neat [...]

Packet Storm Security Advisories
Red Hat Security Advisory 2012-0436-01 - Red Hat Network Satellite is a systems management tool for Linux-based infrastructures. It allows for provisioning, monitoring, and remote management of multiple Linux deployments with a single, centralized tool. It was found that a remote attacker could upload packages to an RHN Satellite server's NULL organization without any authorization or authentication. Although an attacker cannot put packages into an arbitrary channel and have client systems download them, they could use the flaw to consume all the free space in the partition used to store synced packages. With no free space, Satellite would be unable to download updates and new packages, preventing client systems from obtaining them.

Chaos Communication Congress 28th (28C3) 2011 Abstract: As proposed by Nick Farr et al at CCCamp11, we - the hacker community - are in desperate need for our own communication infrastructure. So here we are, answering the call for the Hacker Space Program with our proposal of a distributed satellite communications ground station network. An affordable way to bring satellite communications to a hackerspace near you. We're proposing a multi-step approach to work towards this goal by setting up a distributed network of ground stations which will ensure a 24/7 communication window - first tracking, then communicating with satellites. The current state of a proof of concept implementation will be presented. This is a project closely related to the academic femto-satellite movement, ham radio, Constellation@Home.

Packet Storm Security Advisories
Red Hat Security Advisory 2011-1794-01 - Red Hat Network Satellite provides a solution to organizations requiring absolute control over and privacy of the maintenance and package deployment of their servers. It allows organizations to utilize the benefits of the Red Hat Network without having to provide public Internet access to their servers or other client systems. A cross-site scripting flaw was found in the RHN Satellite web interface. An authenticated RHN Satellite user could use this flaw to perform a cross-site scripting attack against other authenticated users who are using the RHN Satellite web interface.

Hack a Day
The guys over at brainwagon just finished up ANGST, the Arduino n’ Gameduinio Satellite Tracker, a build that displays 160 different satellites in Earth orbit on any SVGA monitor. The build is of course based off an Arduino and Gameduino shield. A real-time clock is always needed for a satellite tracker, so a DS1307 RTC [...]

There’s a new Kickstarter campaign that promises to launch a personalized satellite into orbit for 300 bones. The KickSat project is headed by [Zac Manchester], [Mason Peck], [Justin Atchison] and a few more contributors hailing from Cornell University. Their goal is to launch a CubeSat filled with hundreds of postage stamp-sized satellites and release these [...]

For less than $100 you can buy a little tracking module that will upload your location to a satellite. But you’ll only get latitude and longitude information. [Natrium42] spent some time reverse engineering the hardware, and the communications protocol, to allow custom data to be transferred using a SPOT module. The flat fee for the [...]

This miniature “spy satellite” may not gain the ire of the Chinese People’s Army, but it will certainly look rad on your desk. Besides looking cool, this “satellite” is able to transmit video up to 300 feet away and has sun tracking solar panels for battery recharging. Additionally, it has a LED “thruster” and speakers.

[Shingo Hisakawa] sent in a tip for a for a neat little box called the Levistone that tracks the Internation Space Station with a laser. His video log goes though all the steps for this great little project. [Shingo] originally planned to pull orbital data down from NORAD and send that to an ArduinoBT board [...]
