Technology

A compact folded-lens telescope, drag-resistant materials, a phased-array link, and a low-cost platform, engineered together to fly at 250 km.

Near Earth Orbiter 250km

At the heart of the NEO Platform is Skeyeon’s proprietary Very Low Earth Orbit (VLEO) technology. Operating at approximately 250 km above Earth—far below the altitude of conventional Earth observation satellites—allows us to dramatically reduce the size of the optical system while maintaining exceptional image quality. The result is a compact, cost-effective spacecraft that serves as the foundation for a highly scalable constellation capable of delivering frequent, high-resolution observations. Operating in VLEO also provides an important environmental advantage. Unlike higher orbits where retired satellites can remain for decades, VLEO is naturally self-clearing. At the end of its mission, the NEO Platform will rapidly deorbit and burn up in the atmosphere, leaving no long-term orbital debris and minimizing collision risk.

Skeyeon Near Earth Orbiter (NEO) spacecraft

The NEO Platform carries a purpose-built compact telescope designed specifically for VLEO operations. At 250 km, it delivers 1-meter ground sample distance across a 30 km imaging swath, matching the resolution of satellites flying at five times the altitude, in a package roughly 10 times smaller by volume. The 86.5-megapixel mosaic sensor captures full-color imagery with a revisit rate that no conventional LEO constellation can match at this resolution. The optical system was designed in partnership with Media Lario, one of Europe's leading precision optics manufacturers, and the design has been validated under an active ESA contract.

The NEO Platform is designed as an open hosting platform. The camera is our reference payload, but the platform is sensor-agnostic. The same VLEO advantages that make optical imaging more powerful at 250 km apply equally to radar, RF/SIGINT collection, AIS vessel tracking, hyperspectral sensors, atmospheric instruments, and direct-to-device communications payloads. We are actively working with sensor providers and mission operators to integrate custom payloads. If your mission benefits from proximity to Earth, we want to talk.

Near Earth Orbit is achieved using four principles

Operating at ~250 km requires every subsystem to reinforce the next. Skeyeon brings compact optics, VLEO-tolerant materials, drag-management architecture and a scalable data system together in one purpose-built platform. The objective is not simply to fly lower. It is to make proximity to Earth operationally useful.

Evidence-led design: Skeyeon’s VLEO concept work draws on mission-study analysis and the flight heritage of ESA’s GOCE mission.

01

Optics engineered for proximity

At ~250 km, a target ground resolution can be achieved with a more compact optical architecture than from higher orbits. Skeyeon’s folded-lens concept is designed to pair 1 m-class imaging and a 30 km swath with the low-cross-section geometry VLEO demands so the telescope works with the vehicle’s drag budget, not against it.

02

Surfaces built for the VLEO environment

VLEO is a demanding environment: residual atmosphere creates drag, while atomic oxygen attacks exposed surfaces. NEO combines a compact, low-drag shape with atomic-oxygen-resistant materials designed to protect critical surfaces and reduce the aerodynamic burden. These are not add-ons; they are foundational to the vehicle architecture.

03

Drag management informed by flight heritage

Sustained VLEO operations require continuous management of atmospheric drag and attitude dynamics. Skeyeon’s concept analysis combines propulsion, passive stability and active-control approaches, informed by ESA’s GOCE flight record. GOCE demonstrated drag-free operations at ~254 km and later operated at 224 km using continuous ion propulsion to counter atmospheric drag.

04

A platform designed to turn proximity into service

Proximity matters only when a constellation can convert it into useful data. Skeyeon combines compact payload concepts, high-rate communications and a scalable platform architecture designed for frequent collection, flexible payload integration and persistent coverage. The engineering goal is not one exquisite spacecraft, but an operational VLEO system that can grow with mission demand.
