SpaceX has been putting large numbers of satellites into low Earth orbit as part of its Starlink program to bring broadband Internet to every corner of the planet. The lower orbit means lower latency or round-trip data time between you and the satellite resulting in faster connections and enabling online gaming explains Starlink which other broadband satellites cannot handle.
Low Earth Orbit Satellite

Low orbit satellite. The most popular of these is the International Space Station and the Iridium network of communication. Low earth orbits LEOs can also be effectively used for satellite communications. It is normally at an altitude of less than 1000 km but could be as low as 160 km above Earth which is low compared to other orbits but still very far above Earths surface.
LEO-based telecommunication systems are less costly than medium Earth orbit MEO or high Earth orbit HEO options which also take longer to orbit the Earth. Low orbits have their downsides. For example to reach a Starlink satellite in low Earth orbit data travels a mere 200 or 300 miles which is a far cry from 37000.
Low Earth orbit satellites offer advantages over other forms of satellite communication and are used in data communication and email video conferencing paging and more. Low-Earth orbit is the closest orbit to the Earths surface approximately 1111242 miles above sea level 1802000 km. A low earth orbit LEO satellite is an object generally a piece of electronic equipment that circles around the earth at lower altitudes than geosynchronous satellites.
LEO orbits range from 250 to 1000 miles and signal time delays are of the order of only 5 to 10 msec. Most of the worlds space missions have been to LEO which is where the International Space Station and Hubble Space Telescope are located. Low-Earth orbit is the closest orbit to the Earths surface approximately 1111242 miles above sea level 1802000 km.
A low Earth orbit LEO is as the name suggests an orbit that is relatively close to Earths surface. He enjoys teaching and talking about physics. The low earth orbit is the most populous and most accessible realm of all.
Most of the worlds space missions have been to LEO which is where the International Space Station and Hubble Space Telescope are located. Low Earth orbit satellites are much closer to Earth which solves many of the speed and latency issues satellite internet is known for. LEO satellites orbit between 2000 and 200 kilometers above the earth.
SpaceX is rapidly deploying. Sometimes he takes things apart and cant put them back together. The Federal Communications Commission has serious doubts that low-Earth orbit LEO satellite providersincluding SpaceXcan deliver internet.
Link RF power budgets can be as low as 100 mW with average power needed on the order of 05 W. More than 800 satellites are currently in orbit in the Low-Earth region. Satellites are always moving across the sky requiring antennas to track them for the 10 minutes they are in view and to provide global real-time coverage requires.
