Satellite Lamps is a project investigating one of the most important contemporary infrastructures, the Global Positioning System or GPS. It’s a project curated by Einar Sneve Martinussen, Jørn Knutsen and Timo Arnall as part of the Yourban research project at the Oslo School of Architecture and Design and continues their previous work on revealing the materials of technologies that started in 2009 with RFID and Immaterials: Light Painting Wifi. The project uses Arduino extensively, and is also thoroughly documented:
GPS is widely used yet it’s invisible and few of us really have any idea of how it works or how it inhabits our everyday environments. We created a series of Lamps that change brightness according to the accuracy of received GPS signals, and when we photograph them as timelapse films, we start to get a picture of how these signals behave in actual urban spaces.
