Satellite delay is the noticeable latency due to the limited

speed of light The speed of light in vacuum, commonly denoted , is a universal physical constant exactly equal to ). It is exact because, by international agreement, a metre is defined as the length of the path travelled by light in vacuum during a time i ...

, when sending data to and from satellites, especially distant

geosynchronous satellite A geosynchronous satellite is a satellite in geosynchronous orbit, with an orbital period the same as the Earth's rotation period. Such a satellite returns to the same position in the sky after each sidereal day, and over the course of a day tra ...

s. Bouncing a signal off a geosynchronous satellite takes about a quarter of a second, which is enough to be noticeable, but relaying data between two or three such satellites increases the delay.
