Satellite Communications Glossary

Magnetometer.  A magnetometer measures the strength of the ambient magnetic field.

Medium earth orbit (MEO).  In satellite communications systems, a medium earth orbit (MEO) is a circular satellite orbit of heights between 10,000 km and 15,000 km above the earth.

Meteor.  When a meteoroid enters the Earth’s atmosphere and begins to glow it is called a meteor.

Meteorite.  If a meteor does not burn up during its path through the atmosphere and impacts upon the Earth’s surface it is called a meteorite.

Meteoroid.  Meteoroids are about 1-mm in diameter and move at velocities of 20-27 km/s; micro-meteoroids are largely made of cosmic dust.

Mobile satellite Internet.  Topics in the Satellite Communications Glossary related to Mobile satellite Internet are: Broadband Internet satellite, Two-way satellite Internet, Satellite Internet Providers, Satellite wireless Internet, Satellite Internet Services, Satellite Internet, Satellite Internet Connection, Satellite Internet Access.

Multiple access.  In satellite communications systems, multiple access describes the ability for nodes to access remotely a transmission medium such as a satellite transponder.
