SOLAR SYSTEM

Detailed explanation-1: -It is normally at an altitude of less than 1000 km but could be as low as 160 km above Earth – which is low compared to other orbits, but still very far above Earth’s surface.

Detailed explanation-2: -Globalstar is a low Earth orbit (LEO) satellite constellation for satellite phone and low-speed data communications, somewhat similar to the Iridium satellite constellation and Orbcomm satellite systems.

Detailed explanation-3: -LEO systems orbit the earth at altitudes ranging from about 700 to 3000 km, and unlike GEOs, move with respect to the earth. A typical LEO satellite orbits the earth in less than two hours, which means that a satellite is in view for only a few minutes.

Detailed explanation-4: -The majority of satellites orbiting the Earth do so at altitudes between 160 and 2, 000 kilometers. This orbital regime is called low Earth orbit, or LEO, due to the satellites’ relative closeness to the Earth. Satellites in LEO typically take between 90 minutes and 2 hours to complete one full orbit around the Earth.

Detailed explanation-5: -Due to atmospheric drag, the lowest altitude at which an object in a circular orbit can complete at least one full revolution without propulsion is approximately 150 kilometres (93 mi).
