A high Earth orbit is a geocentric orbit with an apogee farther than that of the geosynchronous orbit, which is 35,786 km (22,236 mi) away from Earth. [1] In this article, the non-standard abbreviation of HEO is used for high Earth orbit.

Satellites in high Earth orbit require the most energy to reach their destination. Satellites in a highly inclined orbit, such as a polar orbit, take more energy than a satellite that circles the Earth over the equator.

Three Classes of Orbit High Earth Orbit. When a satellite reaches exactly 42,164 kilometers from the center of the Earth (about 36,000 kilometers from Earth’s surface), it enters a sort of “sweet spot” in which its orbit matches Earth’s rotation.

2020年3月30日 · For example, to reach a high-altitude orbit like GEO, a satellite doesn’t need the launch vehicle to take it all the way. Instead, the satellite is placed in a special type of transfer orbit called a geostationary transfer orbit (GTO), which serves as a shortcut.

Astranis builds the world's most advanced satellites for high orbits. Our first product, MicroGEO, offers dedicated satellite broadband. But small, radiation-tolerant satellites can do far more than comms.

Satellites in high Earth orbit require the most energy to reach their destination. Satellites in a highly inclined orbit, such as a polar orbit, take more energy than a satellite that circles the Earth over the equator. A satellite with a low inclination can use the Earth’s rotation to …

2017年5月18日 · Based on the distance from Earth, the types of orbits are classified into low earth orbit, medium earth orbit, the geostationary orbit, and high earth orbit. Each of these orbits serves specific applications concerning coverage area, cost, and purpose.

2005年12月8日 · Assembled by experts at the Union of Concerned Scientists (UCS), the Satellite Database is a listing of the more than 7,560 operational satellites currently in orbit around Earth.

2023年1月30日 · There are several types of Earth orbit, and each offers certain advantages and capabilities. LEO is commonly used for communication and remote sensing satellite systems, as well as the International Space Station (ISS) and Hubble Space Telescope. MEO is commonly used for navigation systems, including the U.S. Global Positioning System (GPS).

2017年11月30日 · Although the space beyond Earth’s atmosphere is vast, human-made satellites are typically located in one of three popular orbital regimes: low Earth orbit (LEO), medium Earth orbit (MEO), and geosynchronous orbit (GEO). Figure 1: Popular Orbit Regimes.
