Standard GPS receiving antennas have a large beam width in order to cover
most of the sky.  Even in the Oregon Rainforest the sun is in view most of
the day.

Some satellite transponders have more power and are less prone to 
interference
as they pass in front of the sun.

Typical home TVROs have a number of feedhorns to receive more than one 
satellite.
Different satellites will be affected at different times.
