(Click the button for the best answer below.) a) Global coverage every 24 hours. b) Global coverage at high latitudes every hour, partial coverage elsewhere every 12 hours. c) Regional coverage every 6 hours. d) Global coverage every 12 hours. Discussion d) is the correct response. One POES satellite is capable of providing global coverage over most locations once every 12 hours. While small gaps between orbits do occur at lower latitudes, these gaps drift far enough eastward each day so that no two days pass without coverage.
