Satellite makes one orbit (360°) in about 100 min; i.e., it goes about 3.6°/min, or about 10° in 3 minutes.
With a knowledge of which way the satellite is moving and how fast it is moving, one can estimate viewing time at a particular point.
AMSU coverage (2200 km swath)
SSMI coverage (1400 km swath)

According to the U.S. Space Command (USSC), there are more than 8,000 objects larger than a softball now circling the globe.
Of these, over 2000 are satellites (working and not).
Equal Areas in Equal times: The line joining the planet to the Sun sweeps out equal areas in equal times as the planet travels around the ellipse.
