Low Earth Orbit places satellites very close to the planet, so each pass over the surface covers only a small area. The proximity means the satellite’s line of sight to the ground is limited and the sensor footprint is narrow, producing a small ground coverage region per orbit. In contrast, higher orbits can see much larger areas at once, but that comes with greater altitude and longer time for an orbit, which isn’t characteristic of LEO. Additionally, the short distance to Earth makes the orbital period relatively quick—about 90 minutes—so the satellite circles the planet many times each day. Because of the small ground footprint, a single LEO satellite doesn’t provide global coverage; achieving worldwide coverage typically requires multiple satellites or a constellation.
