Low earth orbit (LEO) is a designation for communication satellites which orbit extends from approximately 300 miles above the earth’s surface up to an altitude of about 1,491 miles.
Benefits of LEO is that as the satellites are closer to the earth the information has less distance to travel which means data transfer speeds are faster than Geostationary (GEO).
Due to locations of LEO satellites, there is less worry of interference from structural or land mass blockage, as well as other common weather interference, meaning a more stable service.
