1575.42 MHz

satellite-controlled kinetic installation

The project is supported by the National Cultural Fund, the Ministry of
Informatics and Communication and the Ministry of Culture Heritage. The installation is a close cooperation between Nextlab, Hydromatic Ltd. and Racional Engeneering.

Special thanks to: Zsombor Gegesy, Viktor Szathmary, Imre Vago, Krisztian Kelner, Anna Barothy (arcus muhely) Andras Grepaly, Marton Elek (geppetto), Endre Kalapacs, Daniel Varga, Balazs Bodo, Adam Siklosi and many more...

1575.42MHz is an object, a robotic arm of 6 sections, which constantly track Global Positioning System satellites. Every section of the sculpture follows the orbit of one of 24 celestial bodies through the horizon, so it moves and changes its appearence permanently.

Below you will find documentation of the working process with images, animations, movies showing the steps of concepting, experimenting and building the installation. As an open development process you can of course use these and we will provide all source codes and patches for free download.

Final steps.

The control software has to be finalized.

There were some difficulties with the controlling algorithm, which takes a lot of time, but finally, talented mathematician Zsombor helps out and provides a solution.

We experience some mechanical problems on certain joints, we have to fix them by disassembling and reassembling the arms again and again. After some days of permanent work, some measuring units report wrong data to the system and it turns out that they become unscrewed after a while.

At the same time we begin with the video documentation.
