If you have an interest in trying to measure sun noise, you might like
to have a look at the "itty bitty radio telescope".

Exactly geosyncs have sun outages as the sun aligns with the sat and your
dish.
GPS because the sats are distributed do not suffer from the effect.

I do not believe it has any effect. The DirecTV satellites are
geostationary at about 22K miles. I used to experience the same phenomenon
in the late 70's with my TVRO receiver at C band. GPS has some 36 or so
satellites in a Medium Earth Orbit (MEO). Blockage, if it can even occur
due to the nature of the receiving antenna, of a single one for a few
minutes will have no discernible effect in my opinion. 73 - Mike

Subject: [time-nuts] Sun Outage
Two days this week, there was a 3 or 4 minute outage on DirecTV as the sun
aligned with the satellite and my dish. So I was wondering what kind of
effect this has on the GPS system and especially timing receivers.
