Equatorial low Earth orbits (ELEO) are a subset of LEO. These orbits, with low orbital inclination, allow rapid revisit times over low-latitude locations on Earth. Prograde equatorial LEOs also have lower delta-v launch requirements because they take advantage of the Earth's rotation.

2024年12月21日 · Low Earth orbit (LEO), region of space where satellites orbit closest to Earth’s surface. There is no official definition of this region, but it is usually considered to be between 160 and 1,600 km (about 100 and 1,000 miles) above Earth. Satellites do not orbit below 160 km because they are.

2022年5月30日 · In very simple terms, low Earth orbit (LEO) is exactly what it sounds like: An orbit around the Earth with an altitude that lies towards the lower end of the range of possible orbits.

2024年4月7日 · What is LEO (low Earth orbit)? Low Earth orbit (LEO) encompasses Earth-centered orbits with an altitude of 1,200 miles (2,000 km) or less. This orbit is considered near enough to Earth for convenient transportation, communication, observation, and resupply.

2025年1月6日 · NASA’s LEO Microgravity Strategy effort aims to develop and document an objectives-based approach toward the next generation of human presence in low Earth orbit to advance microgravity science, technology, and exploration.

2020年3月30日 · A low Earth orbit (LEO) is, as the name suggests, an orbit that is relatively close to Earth’s surface. LEO is considered to be under altitudes of 2000 km, this upper limit a consequence of the Van Allen belts above and the harsh environment they create.

2024年4月16日 · Low Earth orbits (LEO) are orbital paths around the Earth defined by altitudes ranging from approximately 100 to 2,000 kilometres (Figure 1) (Defense Intelligence Agency, 2019, p.12).

2024年2月1日 · Low Earth Orbit (LEO) encompasses satellites that orbit the Earth at altitudes ranging from approximately 160 to 2,000 kilometers (about 100 to 1,200 miles). The proximity of LEO satellites to the Earth’s surface allows for rapid orbit times—often completing a full orbit in about 90 to 120 minutes.

Low earth orbit (LEO) is defined by two characteristics. First, an object in LEO has an orbital pattern that is earth-centric. This means that the object itself orbits earth (as opposed to the moon or another planet). Secondly, LEO is defined as having an altitude of less than 2000 km (1200 miles). Like all objects that orbit the earth (whether ...

2025年1月12日 · We talk about rockets and low Earth orbit (LEO) a lot, but we rarely explain where it is and why it's essential. Let's figure it all out. How High Is Low Earth Orbit?
