VLEO Offers Better Imaging, Lower Power, and Natural Deorbiting for Satellites

Choosing an orbit for a satellite always involves trade‑offs, but recent discussions in the aerospace community highlight the growing appeal of Very Low Earth Orbit (VLEO). VLEO, defined as altitudes between 100 km and 450 km (62–280 miles), offers distinct operational advantages that are attracting both commercial and scientific operators.

The lower altitude improves image resolution for remote‑sensing cameras, allowing finer detail without the need for larger optics. Communication and radar payloads also benefit, as the reduced distance to ground stations lowers power requirements and can shorten transmission latency. Additionally, the increased atmospheric drag at these heights naturally deorbits defunct satellites, providing a passive end‑of‑life cleanup mechanism that can reduce space debris.

While VLEO presents challenges such as higher drag forces and the need for robust propulsion or drag‑control systems, the benefits for imaging fidelity, power efficiency, and debris mitigation are prompting a shift in mission design. As agencies and private companies weigh these factors, VLEO is poised to become a more common choice for next‑generation satellite constellations.
