Using computers for satellite operation was a great step ahead in the 80s. My first setup was a Basic program on a Sinclair ZX-81 with a Z80 core. I think that was 1981 or 82. It did only the prediction, no automatic antenna tracking, that was done manually.
Before we had to use an "OSCARLATOR" printed on paper. I wonder whether someone still has such an original Oscarlator. Would be nice to get a copy.
