Hi All,
Has anyone suggested that we record our own satellite imagery from the satellites whizzing around?
Australias Landsat imagery is recorded in Alice Springs (as far as I know) -23.758824 133.881688 There is another dish just to the east as well. Dont know what frequencies are used or whether it is encoded.
I briefly worked on the CSIRO receiver site (for 2 days in 1994) at Droughty Hill in Tasmania, across the river from the CSIRO at Battery Point and was told the Landsat downlink was 105 MegaBits per second. It was being recorded to 8 mm video tape and then transported by road to the HQ for chewing on the super computer they had at the time.
With a little researching, we could find out the frequencies and modulation method and if it is encoded.
If it is encoded, then another possibility, although a bit far fetched, is to record low resolution LEO (Low Earth Orbiting) weather sat imagery over many days or weeks, and add it together and process it to build up higher resolution. Don't know if this could be done or not.
Anyone interrested?
