Editing Latency (engineering) (section)

===Satellite transmission===
Satellites in [[geostationary orbit]]s are far enough away from Earth that communication latency becomes significant – about a quarter of a second for a trip from one ground-based transmitter to the satellite and back to another ground-based transmitter; close to half a second for two-way communication from one Earth station to another and then back to the first. [[Low Earth orbit]] is sometimes used to cut this delay, at the expense of more complicated satellite tracking on the ground and requiring more satellites in the [[satellite constellation]] to ensure continuous coverage.
