An Eye from Above is an installation that uses a modified antenna and a radio tuned to 137 MHz to translate a live signal from a NOAA satellite into an image of the surrounding sky. Image formation and loss behave analogously to the reception quality of the signal, like a slow blink of the eye that takes place from the satellite's appearance above the horizon to its disappearance below the horizon.

 

Traveling at over 20,000 km/h, the NOAA 15, NOAA 18, and NOAA 19 satellites cross our skies and continuously scan clouds and radiation energies in the visible and infrared ranges. Launched into orbit between 1998 and 2009 by the US National Oceanic and Atmospheric Administration (NOAA), their purpose is to provide data for weather forecasting. Their orbits are known; it is possible to receive their transmissions if you are in the right place at the right time and have the right equipment.

 

When the satellite appears above the horizon, its signal slowly emerges from the ambient noise and produces a characteristic pulsation of 120 BPM. This pulsation can be visualized using a software radio: slowly, line by line, a (neph) analysis based on satellite data appears, showing the degree of cloud cover and the geographical distribution of cloud types within a radius of 2000 kilometers above us. The visualization offers a shift from our perspective to that of a space object; the antenna makes the electrical energy that permeates our bodies and our environment perceptible amid a multitude of other artificial signals.
