Why Space Matters: GEO Satellite operations, Part 2–FOV/FOR-it things

In the first lesson, you learned (if you didn’t already know) a spacecraft in geosynchronous orbit is very far away from the Earth—a little over 26,000 miles. Before going any further, an explanation of Field of Regard (FOR) versus Field of View (FOV) is in order since we will initially be talking about weather imagery satellites.  […]
