A satellite at this height takes 12 hours to complete an orbit. This distance puts it in the high Earth orbit category. Satellites in low earth orbit (LEO) satellites complete one orbit roughly every 90 minutes at a height of between 100 and 500 miles above the earth's surface.
I think that it doesn't matter, as long as the satellite maintains a circum-solar orbit.(?)
They all fly 12,550 miles (20,200 km) above the earths surface in medium earth orbit (MEO) which causes them to orbit the earth precisely twice per day. To plot orbiting satellites and paths on a flat, static map would create quite a mess. It is the orbit used by the Global Positioning System (GPS… The satellites have a speed of 3.9 km per second and a nominal period of 12 h sidereal time (11 h 58m 2 s), repeating the geometry each sidereal day. This is the height above the Earth plus the radius of the Earth. Orbits in this height are referred to as MEO – medium earth orbit. ... others such as GPS and even those satellites used for mobile phones are much lower. Navigation satellites, like the kind used by your car's GPS, work well at this altitude. A world map of the positions of satellites above the Earth's surface, and a planetarium view showing where they appear in the night sky.
Russia's orbiting space station Mir is another manned satellite. To maintain an orbit that is 22,223 miles (35,786 kilometers) above Earth, the satellite must orbit at a speed of about 7,000 mph (11,300 kph). Rarely, they fly near 400 miles altitude.

GPS satellites orbit at a height of about 12,000 miles (19,300 km) and orbit the earth once every 12 hours. Orbits are nearly circular, with eccentricity less than 0.02, a semi-major axis of 26 560 km, i.e.
The GPS satellites are not in a geostationary orbit, but rise and set two times per day. Figure 10 shows results for an occultation event of GPS satellite SVN 47 (PRN 22) on September 2, 2013, between approximately 17:42 and 17:48 UTC. GPS navigation satellites are in a medium-Earth orbit at about 20,000 kilometres altitude above the Earth. At any inclination, a geosynchronous orbit synchronizes with the rotation of the Earth. The GPS space segment consists of a constellation of satellites transmitting radio signals to users. The GPS satellites circle the Earth at an altitude of about 20,000 km (13,000 miles) and complete two full orbits every day. Watch video; View pre-launch news release; Jun 2019: The second GPS III satellite was encapsulated in preparation for its planned July launch. It’s specially designed to enable GPS satellites to see a lot of the Earth all at one time without having to build lots and lots of satellites. Since a sidereal day is about 4 minutes shorter than a solar day, a GPS satellite orbits once every 11 hours and 58 minutes. 24 satellites in 3 orbits (8 satellites in each orbit) 64,8° inclination, repetition of ground trace every 17 orbits (8 days) → better availability in high latitudes than GPS Orbit height: 19 100km Orbit time: 11h16m Average satellite life expectancy 3 years Satellite mass 1,48t Altitude classifications for geocentric orbits.
The conversion is done by a converter (ADC: Analog - Digital-Converter). an altitude of 20 200 km.
More specifically, the time it takes for the Earth to rotate on its axis is 23 hours, 56 minutes and 4.09 seconds, which is the same as a satellite in a geosynchronous orbit. A virtual globe allows us to plot satellites along with their height … TET-1 was launched into a sun-synchronous LEO orbit at a height of approximately 500 kilometers with an inclination of 97.5 degrees on July 22, 2012. That orbital speed and distance permit the satellite to make one revolution in 24 hours.
