Why is there a time delay when sending information via a geostationary satellite?

Why is there a time delay when sending information via a geostationary satellite?

Proposed OneWeb network Typical single hop latency, corresponding to 1500km + 1500km would be 10 mS. If the terrestrial end points are not within the coverage of a single satellite (approx 1000km x 1000km) then the distance will be greater, with inter-satellite links via other satellites.

How long is the satellite delay?

Typically, during perfect conditions, the physics involved in satellite communications account for approximately 550 milliseconds of latency round-trip time. The longer latency is the primary difference between a standard terrestrial-based network and a geostationary satellite-based network.

What is the speed of satellite communication?

Radio waves are used to carry satellite signals. These waves travel at 300,000 km/s (the speed of light). This means that a signal sent to a satellite 38,000 km away takes 0.13 s to reach the satellite and another 0.13 s for the return signal to be received back on Earth.

What is the time period of satellite used for communication satellite?

A communications satellite is in a geostationary equatorial orbit with a period of 24 h.

Why is there a satellite delay?

Satellite delay is the noticeable latency which occurs due to the speed of light, when sending data to and from satellites, especially the much further out geosynchronous satellites.

What causes satellite delay?

What is the time delay for a television signal that is sent via satellite?

(See Figure 5-4.) When you transmit a signal, there is an approximately half-second delay between the time you initiate your transmission and the time it reaches the satellite.

How is satellite used for communication?

Satellites communicate by using radio waves to send signals to the antennas on the Earth. The antennas then capture those signals and process the information coming from those signals. Information can include: where the satellite is currently located in space.

How are satellite communication and terrestrial communication used in wireless communication?

A communication satellite is a microwave repeater station in a space that is used for telecommunication, radio and television signals. A communication satellite processes the data coming from one earth station and it converts the data into another form and send it to the second earth station.

What is satellites delay?

Satellite delay is the noticeable latency which occurs due to the speed of light, when sending data to and from satellites, especially the much further out geosynchronous satellites.

What are the issues with using satellites in a geostationary orbit?

One of the issues with using satellites in a geostationary orbit is the delay introduced by the path length. The path length to any geostationary satellite is a minimum of 22300 miles. This assumes that the user is directly underneath the satellite to provide the shortest path length.

How long does it take to bounce a signal off a satellite?

Bouncing a signal off one geosynchronous satellite takes about a quarter of a second, which is enough to be noticeable, but relaying data between 2 or 3 such satellites increases the delay further. ^ Elbert, Bruce R. (2004). The Satellite Communication Applications Handbook.

How far away can a geostationary satellite be seen?

A geostationary satellite is visible from a little less than one third of the earth’s surface and if you are located at the edge of this area the satellite appears to be just above the horizon. The distance to the satellite is greater and for earth stations at the extreme edge of the coverage area, the distance to the satellite is approx 41756 km.
