Speaking of Sat TV dishes for SETI

To recap, I mentioned the opportunistic and cheap usage of Satellite TV dishes for SETI.
I also mentioned I would have to actually learn something.

The limit of using sensors such as these are the accuracy of location being significantly
less than a quarter wavelength and a commensurate time standard. As they are both error
sources the accuracy of location and time increases individually. So anything like dish
frequencies is so far out of the ballpark as not to be considered.

Working at it backwards affordable placement accuracy is GPS. At best 2 meters or so. If
1/10th wavelength were good enough and time errors were negligable then the highest
frequency would be the 20 meter shortwave band. I see no way around it.

We do have a way to calibrate sat dishes in space with a signal from the satellite. A
short pulse in the horizontal blanking (where they hide the data for the deaf) would
calibrate 60 times per second. There may be something usable existing system that the
uplink and the satellite use to talk to each other.

This does not give us a usable time sync.

More reading is needed.
