It depends one what satellite it is. Differents types of satellite orbit the Earth at different altitudes. In Low Earth Orbit satellites travel between 160km and 2000km above the Earth, in Medium Earth Orbit they travel between 2000km and 35000km above the Earh, and in Geostationary Orbit they travel above 160km and below 35000km around the Equator.

TaigaGoogle does *not* operate its own satellites, but the satellites that provide imagery to Google include GeoEye-1, QuickBird, WorldView-1, WorldView-2, and others.
GeoEye-1 orbits the Earth 15 times per day flying at an altitude of 681 kilometers or 423 miles. Likewise, QuickBird and WorldView-1 are basically at the same altitude of 450 and 496 km respectively. Note QuickBird-1's orbit decayed in Jan 2015 when it re-entered Earth's atmosphere. QuickBird II (or QuickBird-2) is still in operation.
WorldView-2 is at a higher altitude of 770 kilometers or 478 miles.

If altitude increases the required orbital speed of a satellite should?
For any body in a closed orbit around another body, the farther apart the two bodies are, the slower the satellite moves in its orbit.. When the Space Shuttle is in "low earth orbit", it moves faster than the Moon is moving in its orbit. A satellite in an elongated orbit, that spends some of the time close to the earth and some of the time farther away, moves fastest at its lowest altitude, and slowest when it is furthest away.
True or False An artificial satellite in a high orbit will slow down and lose altitude due to the pull of Earth's gravity?
False. Why would it slow down? There is no friction in a high orbit; a satellite can orbit indefinitely. Only in low orbits will satellites slow down and fall from orbit, and the cause is the friction of the extremely tenuous final traces of Earth's atmosphere.
How long does it take to build a satellite?
The time it takes to put together a satellite varies on the size and structure of the satellite. A simple satellite could be put together in a couple of months, where a large science mission could take ten or more years.
A satellite in a low earth orbit moving faster than a satellite in a geosynchronous orbit?
YES As height increases, speed of satellite decreases.
What force keeps satellite in orbit around the Earth?
There is only one main force acting on a satellite when it is in orbit, and that is the gravitational force.
