MEO satellites orbit the earth at higher altitudes and therefore provide a greater coverage area to the extent that a company with 24 MEO satellites in position will have four covering any given spot on the earth at any time during the day.
A medium earth orbit (MEO) satellite is one with an orbit within the range from a few hundred miles to a few thousand miles above the earth's surface. Satellites of this type orbit higher than low earth orbit (LEO) satellites, but lower than geostationary satellites. Other MEO satellites revolve in elongated orbits.
Medium Earth Orbit (MEO)
The most common use for satellites in this region is for navigation, such as the GPS (with an altitude of 20,200·kilometres), Glonass (with an altitude of 19,100·kilometres) and Galileo (with an altitude of 23,222·kilometres) constellations.Revenue Divisional Officer

GPS employs a constellation of at least 24 satellites in Medium Earth Orbit (MEO), transmitting one-way radio signals that are used to calculate three-dimensional position, velocity, and time, primarily for Earth and near-Earth users.
A high Earth orbit is a geocentric orbit with an altitude entirely above that of a geosynchronous orbit (35,786 kilometres (22,236 mi)).
Civilian photography satellites, such as the American Landsat and the French Spot, orbit at altitudes ranging from 300 to 600 miles. American NOAA and Russian Meteor weather satellites are at these same altitudes. Spysats and military communications satellites dominate space from 600 to 1,200 miles altitude.
MEO is not a valid scrabble word.
No. Satellites must be constantly orbiting the Earth, at high velocities, in order to keep themselves from falling back to the ground due to the Earth's gravity. These satellites would appear to be stationary, always in the exact same spot overhead, but they are still orbiting.
A low Earth orbit (LEO) is an orbit around Earth with an altitude above Earth's surface of 2,000 kilometers (1,200 mi), and an orbital period between about 84 and 127 minutes. Objects below approximately 160 kilometers (99 mi) will experience very rapid orbital decay and altitude loss.
Other satellites in medium Earth orbit include Glonass (with an altitude of 19,100 kilometres (11,900 mi)) and Galileo (with an altitude of 23,222 kilometres (14,429 mi)) constellations. Communications satellites that cover the North and South Pole are also put in MEO.
Artwork: Communications satellites bounce signals from one side of Earth to the other, a bit like giant mirrors in space. The satellite boosts the signal and sends it back down to Earth from its transmitter dish (red) to a receiving dish somewhere else on Earth (yellow).
