In order for a satellite to stay in space and not fall to earth, it has to move in orbit round the earth. Many satellites and the International Space Station are in low orbit and at that distance above the earth orbit the earth in a couple of hours or so. However, if the orbit is around 26000 miles up, then at that distance the time it takes for a satellite to freely orbit is exactly one day or 24 hours. This means that the satellite is always above the same spot on earth, as the earth also takes 24 hours to rotate. Thus, if we could see the satellite in the sky it would not move across the sky like the International Space Station but it would stay in the same place in the sky.

This means that they can be used for communication - when you telephone, say, from Europe to the USA then the signals are received by these satellites, amplified and relayed across the world to the receiver of the call. As the satellites are in the same place in the sky all the time, you can call at any time of the night or day. However, if the satellite moved across the sky in low orbit you would only be able to use it when it was in the sky - in other words you could only telephone for a few minutes at a time and then have to wait until it was back in the sky again.

Similarly, these satellites are used for navigation in sat-navs. As the satellite is always in the same point in the sky, it can work out your position at any time of the night or day.

The term 'geostationary' comes from 'geo' meaning 'earth' (as in geo-graphy, geo-thermal etc) and 'stationary' - meaning not moving i.e. the satellite is 'not moving above earth'.

C What can satellite images tell us about the weather?

Satellites above the atmosphere can get a clear, big picture of Earth's cloud formations. By analysing these cloud patterns, meteorologists can forecast how these clouds will change and move, and predict the weather, be it rain or shine, for many areas. For example, hurricanes can be easily spotted from satellites but not easily spotted from ground due to its size, and thus satellites come in very helpful. Also, infra-red satellite forecasting can also determine the temperatures in different areas on Earth's surface, which aids meteorologists in finding out cloud heights, cloud types, water cycles and sea surface termperatures (an important factor in the formation of hurricanes).


What is the ratio of a geostationary satellite's speed to your speed?

Whenever you talk about speed, it has to be relative to something, and if you want to compare two speeds, then they both have to be relative to the same thing, which you haven't identified. Relative to my left thumb, one of those speeds (mine) is zero, and the other one is nominally zero. Relative to the tip of a blade on the propeller of an aircraft in flight, or a flea on the fan-belt of my car, both of those speeds are constantly changing in very complex ways, and in order to describe either of them, I'd need a ton of additional information that you haven't provided.


What is the telephone country code for satellite telephones?

Satellite telephones use several different country codes, depending on the company providing the service. Note that substantially higher call charges may apply for calls to satellite phones, compared to calls to ordinary land-based phones.Inmarsat uses country code +870, primarily for ship-to-shore calls. (Inmarsat formerly also used country codes +871 through +874, but now uses only +870.)Country code +881 is used for global satellite phones, with the next digit identifying the company: 6 or 7 for Iridium, and 8 or 9 for Globalstar. (+881 0 and +881 1 are reserved for ICO Global/Pendrell, and +881 2 and +881 3 for Ellipso, but they are not operational.)Country code +882 is used for various international networks, with the next two digits identifying the network operator. The following networks are used for regional satellite phones:+882 13 = Telespazio/EMSAT+882 16 = Thuraya+882 20 = ACeS/Garuda+882 38 = (was assigned to Ellipso, in addition to +881 2 and +881 3)Country codes +875, +876, and +877 are reserved for maritime mobile services, but have not yet been activated.(The plus sign means "insert your international access prefix here." From a GSM mobile phone, you can enter the number in full international format, starting with the plus sign. The most common prefix is 00, but North America (USA, Canada, etc.) uses 011, Japan uses 010, Australia uses 0011, and many other countries use different prefixes.)

How do satellites move?

A Satellite movement behaves in two ways. Its orbit may be defined either as "geosynchronous" or "geostationary". Geosynchronous satellites move together with the Earth's own orbit, so it revolves in the same way as the earth is. Geostationary satellites remain statically in place for a certain coordinate...

Satellites cannot orbit one country. They may remain in geostationary orbit, but only at the equator. Therefore no satellite stays above only New Zealand.

What is the typical upload speed of a satellite a broadband connection?

broadband satellite is an alternative for customers who cannot get cable or DSL connections A satellite connection does not require a phone-line or cable, but uses a satellite dish for two way communication, download speeds are up to 500kbps: uploads are closer to 56kbps it takes time for the signal from the satellite dish to rely to your internet service provider (isp) through the satellite orbitting the earth.

What are the strategic locations of satellites?

There are two special locations for satellites: * geostationary orbits * polar orbits For satellite communication, it is very convenient if one can align fixed ground antenna to point at the satellite. The only way to get a satellite to stay exactly in front of a fixed ground antenna is to put it in geostationary orbit -- an altitude of 35,786 km above sea level above the equator. Other than geostationary orbit, there are a few other orbits that hold a satellite approximately in front of a fixed ground antenna for several hours -- the Molniya orbit and the Tundra orbit. Satellites designed to take photos of Earth (weather satellites, spy satellites, etc.) are typically in a polar orbit. Sooner or later, a satellite in polar orbit will end up directly overhead any given point on Earth. Typically these satellites are in an orbit very roughly 1000 km above sea level (roughly 100 minute orbit), because higher orbits are more expensive, and orbits less than a few hundred km rapidly decay from air friction.
