FCC Technician Exam Question Of The Day (T8B10)

Q) What do the initials LEO tell you about an amateur satellite?

A) The satellite is in a Low Earth Orbit

NJ2X Notes:
LEO (Low Earth Orbit), is generally defined as an orbit below an altitude of 2,000 kilometers (1,200 mi).  Given the rapid orbital decay of objects below approximately 200 kilometers (120 mi), the commonly accepted definition for LEO is between 160 kilometers (99 mi) and 2,000 kilometers (1,200 mi) above the Earth's surface.
