A Cyberdeck for Satellite Hacking

Cyberdecks are retro-style PC builds inspired by older sci-fi novels. The idea was first introduced in the 1980s when computers were still large, expensive, and immobile. In the sci-fi novels the characters would carry around clunky but portable computers (a.k.a cyberdecks) that would allow them to access the matrix. Fast forward to today and portable computers are almost a necessary part of modern life. However, the idea of cyberdecks is still alive and well. Indeed, small communities exist to share information and pictures for cyberdeck builds. One user by the name of Gabe Emerson built his own cyberdeck, called the Spacedeck v1, with the ability to monitor weather satellites.

Emerson has a website and Youtube channel called “saveitforparts.” It is named after his desire and habit of saving most things others would throw out. The Spacedeck is a cyberdeck build that is born out of this collection of old supplies. Whereas single board computers are generally found at the center of many modern cyberdeck builds, the Spacedeck utilizes a surplus police car computer purchased from an online auction. In fact, six of them were purchased for the price of a dollar. After trying and failing to load Mint OS and Lubuntu Linux distributions on the older computer, it was found that Q4OS would work, a desktop oriented and Debian based Linux distribution. In addition, it was capable of running the desired software for the build. This includes GQRX, a common SDR software, Gpredict for satellite tracking, and additional satellite monitoring tools such as GOEStools and WXtoIMG.

Some of the hardware included in the cyberdeck build includes a RTL-SDR radio, various amps and filters, Wi-Fi modules, a satellite meter, a PTZ controller for satellite dishes, and a LNB power injector. While all of these parts are re-use from Emerson's parts collection, he does admit spending money to acquire a mini RGB mechanical keyboard as well as new batteries to keep the project powered reliably and longer than anything in his spare parts bin could offer.

The cyberdeck came together as a modular type of build. Most of the pieces are held in place by Velcro which allows them to be easily swapped out. It also provides a convenience as the pieces can be used in place or taken out for ease of use. Furthermore, the case features two custom panels. The panels are made out of plexiglass and are covered with a vinyl sticker which features text and graphics for labeling ports and features. The panel on the side of the computer screen breaks out connections such as USB, audio, and SD card readers. In addition, it also has lots of radio connections broken out. These include connections for the SDR radio and amplifier and filter modules. The second panel has a USB hub, a break out for the satellite meter, a breakout for 12V power, and the PTZ controller. To finalize the project Emerson takes it out at night to track a NOAA weather satellite. Using the Spacedeck v1 he demonstrates capturing and decoding the wireless transmission from the satellite as it passes over head in the night sky.
