Detailed explanation-1: -The maximum signal propagation time of a geosynchronous satellite transmission is about millisecond.
Detailed explanation-2: -For geostationary orbit satellites (which are used for communications), the propagation delay from the Earth terminal to the satellite could be as long as 120 ms. For a packet to be transmitted to the satellite and back to the Earth terminal, a delay of 240 ms is expected.
Detailed explanation-3: -GEO systems have a high propagation delay of at least 250 ms from ground terminal to ground terminal. If two GEO hops are involved, then the inter-satellite link delay could be about 240 ms. Other delay components are additionally incurred, and the total end-to-end delay can be higher than 400 ms.
Detailed explanation-4: -Geosynchronous satellites, on the other hand, orbit the Earth at about 36, 000 kilometers above the equator and single hop is calculated to take 270 milliseconds one way or 540 milliseconds for a round trip.
