Pioneering Spacecraft Architecture

HALO represents a new generation of spacecraft engineering. Developed jointly by OrbitalX and Infinity Space, the saucer-shaped form factor is engineered to improve manoeuvrability, maximise structural efficiency, and seamlessly integrate advanced metamaterial technologies — delivering innovative defence solutions trusted by government and defence partners.

Capability

A new shape for sovereign defence

A pioneering saucer-shaped spacecraft platform engineered for defence, surveillance, and reconnaissance — combining structural efficiency, agile manoeuvrability, and advanced metamaterial integration.

Disc Geometry

Manoeuvrability by Design

The saucer form factor delivers improved attitude control authority and rapid re-orientation — outperforming conventional rectangular satellite geometries in agility and mission tempo.

Metamaterials

Engineered at the Surface

HALO integrates advanced metamaterial layers across its outer surface, enabling next-generation sensing, signal manipulation, and electromagnetic behaviours unattainable with conventional spacecraft skins.

Defence-Ready

Built for the Mission

Engineered from inception for surveillance and reconnaissance — resilient, mission-ready, and aligned with the operational requirements of UK government and allied defence partners.

Joint Mission

OrbitalX × Infinity Space

A partnership in next-generation defence

HALO is delivered as a joint mission between OrbitalX, the platform integrator, and Infinity Space, the sovereign space-systems specialist.

OrbitalX brings deep expertise in saucer-shaped spacecraft architecture and metamaterial integration, while Infinity Space contributes its proven heritage in flight-ready quantum payloads, secure communications, and trusted-node mission infrastructure. Together, the two organisations deliver a single, sovereign capability optimised for UK government and allied defence customers.

Manoeuvrability

Structural Efficiency

A platform engineered for advantage

The saucer geometry distributes structural loads radially, producing a stiffer, lighter, and more thermally balanced spacecraft than conventional rectangular buses.

Reaction wheels and control moment gyros are positioned for optimal authority around all three axes, delivering exceptional pointing agility for tactical reconnaissance and rapid re-tasking. The disc profile also enables more efficient solar coverage during orbital manoeuvres, sustaining higher peak power for sensor-intensive operations.

Metamaterials

Advanced Surface Engineering

Materials that do more than hold the structure

HALO's outer surface is more than skin — it is an active engineering layer.

OrbitalX's research into metamaterials enables surfaces that can selectively reflect, absorb, or steer electromagnetic energy — opening capabilities across reconnaissance, low-observable design, and advanced sensing. Integrated directly into HALO's disc form, these materials transform the satellite skin into a functional element of the mission payload itself.
