What type of satellite orbit minimizes the propagation delay?
LEO satellites have lower propagation delays due to their lower altitudes, but many satellites are needed to provide global service. While LEO systems have lower propagation delay, they exhibit higher delay variation due to connection handovers and other factors related to orbital dynamics [IQTC97].
What is propagation delay in satellite communication?
Propagation delay is considered to be the time the signal takes to travel from the Earth transmitting station to the Earth Receiving station where the signal encounters an uplink and downlink way. In order to calculate the propagation delay, we have to take the light speed of into account.
What is VSAT latency?
The total latency for VSAT service is about 500 – 650 ms.
How much delay occurs in transmission and reception in satellite communication?
The expected propagation delay will be a little more than 100 milliseconds per hop. 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.
How do you solve propagation delay?
It can be computed as the ratio between the link length and the propagation speed over the specific medium. Propagation delay is equal to d / s where d is the distance and s is the wave propagation speed. In wireless communication, s=c, i.e. the speed of light.
Why is satellite latency so high?
Radio waves sent from a satellite are moving at the speed of light, but because of the greater distances the signal must travel, the latency is higher than that of terrestrial providers.
