As for a control room, the whole point is for it to look impressive so it needs so it needs a load of screens showing diagrams of orbit's and flashy graphics. It needs an intercom or radio base station with moon-landing-style shrill roger bleep to talk to the guy up on the roof who is doing all the work waving a yagi on a broom handle about looking for the strongest signal.

The aerial suggested to be used for the reception may be enhanced by using a cross-yagi. It's been used for AMSAT/OSCAR amateur radio communication as preferred option, canceling out most of the polarisation loss due to satellite rotation/tumbling. The complexity on the aerial will increase,but its a "passive" gain,where you will be able to get longer passages on each orbit, and also a steadier signal overall. | |||
