With large number of low-earth-orbit satellites and the geo-synchronous orbit stuffed full of communications satellites, there aren't all THAT many "medium" altitude satellites. But there are some.
The GPS navigation satellites, for example, are in highly inclined 12-hour orbits, and an unknown number of military "spy" satellites are in that middle range.
At present there are around 24-32 satellites orbiting in medium earth orbit(11,000 miles)more the satellites more accurate navigation is produced.
If they are in the atmosphere (low earth orbit), satellites are in the ionosphere. If they are in higher orbits, satellites are considered to be outside the atmosphere.
They usually get their energy from the Sun, but they may also have a nuclear reactor. That's how they get their energy; how they work in detail would depend on what they are supposed to do. There are satellites for many different purposes.
I believe that NASA not only sends the satellites up they also monitor them on a daily basis.
Satellites cannot orbit one country. They may remain in geostationary orbit, but only at the equator. Therefore no satellite stays above only New Zealand.

Satellites are dispersed in various orbits around the Earth, including low Earth orbit (LEO), medium Earth orbit (MEO), and geostationary orbit (GEO). They are positioned strategically to provide global coverage for communication, weather monitoring, navigation, and various other services.
GPS satellites orbit the Earth at an altitude of about 20,000 km in medium Earth orbit (MEO). They move in precise paths to ensure global coverage and are spaced evenly to provide accurate positioning data. The satellites follow elliptical orbits that repeat every 12 hours.
Satellites orbit in several different regions of space in the sky. Orbits fall into 3 main categories based on distance: Low Earth Orbit (LEO) at an altitude of 160 - 2000 km, Medium Earth Orbit (MEO) at an altitude of 2000 - 35000 km, and High Earth Orbit (HEO) at altitudes greater than 36000 km. One special orbit in which a large number of satellites have been placed into is a geosynchronous earth orbit (GEO), which is at the exact distance such that the satellite orbits the earth at the same angular velocity at which the earth spins. Most satellites orbit in circular orbits. A few are in elliptical orbits in which their distance varies.
No, all satellites do not orbit Earth at the same altitude. An good overview of this can be found on http://www.idirect.net/Company/Satellite-Basics/How-Satellite-Works.aspx. This overview reviews Low Earth Orbit, Medium Earth Orbit and Geostationary Orbits.
The Earth orbit in which satellites appear to be stationary is called the, "Geostationary Orbit". Some call it a synchronous orbit.
Satellites orbit Earth in the thermosphere and exosphere, which are the upper layers of the Earth's atmosphere. The exosphere is the outermost layer of the atmosphere where most satellites, particularly those in geostationary orbit, are found.
Natural satellites are organic objects that orbit the earth such as the moon. Artificial satellites are objects humans propel through the earth's atmosphere in order to orbit the earth such as satellites for TV and radio signals.
Satellites orbit the earth for a few years then fall to earth however they are directed to fall to the sea
