meo

MEO is an acronym used for more than one topic, most notably a class of satellite orbits and a major telecommunications brand in Portugal. In space contexts, MEO refers to Medium Earth Orbit, a region of space between low Earth orbit and geostationary orbit. Satellites in MEO orbit at altitudes roughly between 2,000 and 35,786 kilometers above the Earth. Their orbital periods range from about 2 to 12 hours, depending on altitude. MEO is the orbit adopted by several global navigation satellite systems, including GPS, Galileo, and GLONASS, which use these orbits to balance coverage, satellite visibility, and latency. MEO provides a larger footprint per satellite than low Earth orbit, while generally incurring higher latency and longer revisit times than LEO constellations.

In Portugal, MEO is the consumer brand of Altice Portugal that provides telecommunications and entertainment services. The brand originated with Portugal Telecom and was launched in 2007 to offer mobile, fixed-line, television, and internet services. After the acquisition and restructuring that brought Portugal Telecom under Altice, MEO continued as the flagship brand for the company’s fixed and mobile networks, including services such as MEO Fibra (fiber internet) and MEO TV. MEO competes with other Portuguese providers in mobile, broadband, and pay-TV markets and is distributed nationwide through extensive customer support and retail networks.

Shortly, MEO denotes both a technical term in satellite technology and a major telecommunications brand in Portugal, reflecting its use in very different fields.
