Under Surveillance, a Satellite Sky Chart
30 days of spy-satellites passing above my studio
There are lists of satellites hidden away on the internet. These lists contain information about thousands of artificial objects orbiting the Earth. On the basis of this data one can calculate the position of satellites at any given time.
Sous surveillance is a computer generated image that uses this information in order to make the satellites flight path visible. To make this image, I programmed a software that draws lines based on the position and speed of the orbiting objects.
Sous surveillance uses data about spy satellites, i.e. considered to be “classified” transmitting countries. This data is compiled by hackers, who use telescopes to locate the objects that are being hidden from view. Like a sky chart, the image shows 28,800 passages of spy satellites above my studio over a 30 day period. Each passage in the sky produces a line that varies in position and colour on the basis of the satellite’s orbit.
