Society General Meeting

Talk: Pictures from Space

Gareth Evans

Since the mid 1980’s it’s been possible to receive weather pictures from Polar orbiting weather satellites. As computer power has improved so has the software and part of the talk will explain how it’s done now using cheap electronics and an aerial to suit. Depending on passing satellites it may be possible to demonstrate a live picture. The second part of the talk will expand on receiving Amateur Radio Digital TV signals from a new geostationary satellite (Gareth’s transmitter system for this was displayed at last year’s competition). Depending on sky visibility from the Marshall House back yard, live pictures may well be possible too.
