SOLAR RADIO STATION: RT-32
The live installation is a collaboration among the artists of RIXC (LV) and r a d i o q u a l i a (NZ), Clausthome (LV) musicians, and VIRAC - Ventspils International Radio Astronomy Center (LV) scientists.
Realtime scanning of Solar system's objects is performed in Irbene, Latvia using former military antenna RT-32 of VIRAC radiotelescope. The signal is downsampled to audible frequency and transmitted live via the Internet. The artists' team in Dortmund is turning the noise from the space into realtime sound modelling performance and live video mix which stands as an integral part of the live installation.
The antenna of Irbene radiotelescope is fully steerable, rotating paraboloid 32 m across. It has high surface accuracy, it may operate in the centimeter and millimeter ranges.
RT-32 is a Cassagrain reflector antenna: the dish reflects radiowaves to the hyperbolic secondary mirror and then back to the center, where the secondary focus receives and amplifies the signal for processing.
A receiver for 12 GHz is used to receive the analogue radio signals from the observed sources, which then - by using a system consisting of several frequency converters and filters - is downsampled to audible frequency.
3. LIVE STREAM
The sound signal of realtime observations is encoded into live mp3 stream and transmitted via GPRS modem to the Internet.
4. REAL-TIME PERFORMANCE
Clausthome musicians are modeling realtime stream from the radiotelescope and turning it into live Solar soundscape.
