Very low Earth orbit is a range of orbital altitudes below 400 km (250 mi), and is of increasing commercial importance in a variety of scenarios and for multiple applications, in both private and government satellite operations.

2024年1月24日 · In the evolving landscape of satellite imagery for aerospace and defense, the strategic significance of very low Earth orbit (VLEO) is becoming increasingly apparent.

2023年10月18日 · Very Low Earth Orbit (VLEO), situated at an altitude between 100 and approximately 450 km (most commonly 250-350 km) is becoming increasingly attractive for both commercial and scientific endeavours. "It is easier to get to, requires fewer resources for communications, and allows for smaller payloads.

2023年3月1日 · The startup company EOI (Earth Observant Inc.) Space, based in Louisville, Colorado, is developing a VLEO (Very Low Earth Orbiting) constellation of satellites to collect ultra-high resolution Earth imagery for both government and commercial use.

2023年12月14日 · VLEO refers to orbits between about 100 kilometers and 300 or 400 km (although the exact range depends on who you ask), in contrast to LEO, which starts around 300 or 400 km and extends up to 2,000 km.

A low Earth orbit (LEO) is an orbit around Earth with a period of 128 minutes or less (making at least 11.25 orbits per day) and an eccentricity less than 0.25. [1]

2020年8月28日 · Earlier this month, a small San Francisco-based startup called Earth Observant announced it had won a development contract with the Air Force’s AFWERX technology incubator to advance its design...

2020年8月1日 · Very low Earth orbit (VLEO) can provide significant benefits over higher altitudes. Higher resolution or lower cost missions can enabled by operating in VLEO. Orbital debris collision risk and radiation damage are also shown to be reduced.

What are Very Low Earth Orbits? Typically defined as orbits below 450 km in altitude –When aerodynamic effects become significant Usage over time –Early reconnaissance –ISS and experimental or scientific missions –Commercial (Planet and Spire) and academic nanosatellites (CubeSats) Why are we interested in VLEO?
