GEO describes a specified orbit around the earth that is at a defined distance at 22,236 miles (35,786km) away from earth. It is also defined by several other parameters including velocity (11,052km/hr) and complete orbital rotation (24hr). GEO satellites are designed to match the speed of the earth’s rotation to maintain its position over a specific point on earth. Many GEO satellites are exposed to greater levels of radiation and must be designed to withstand harsher design environments than LEO of MEO satellites. GEO satellites are also designed to have a longer operational life because of their intended applications like weather tracking and global telecommunications.
