Stellar Navigation Beyond GNSS

Designed by Solar MEMS Technologies

As modern operations increasingly rely on satellite navigation, resilient performance in GNSS-denied or degraded environments is essential.

Navigation Beyond GNSS

STELION has been
developed to address
this challenge.

Using advanced stellar navigation technology, STELION determines position, heading, and navigation information by observing celestial references, enabling autonomous and resilient navigation without relying exclusively on external satellite infrastructure.

Designed for operation in contested, degraded, and remote environments, STELION delivers a new layer of navigation assurance for defence, aerospace, maritime, and autonomous platforms.

The Method

What is Stellar Navigation?

01

GNSS-Free Operation

Operates independently from GNSS signals, maintaining full navigation capability in environments where satellite coverage is unavailable or unreliable.

02

Anti-Spoofing & Jamming

Resistant to spoofing and jamming by design, celestial references cannot be faked or disrupted by adversarial electronic warfare systems.

03

Zero RF Signature

Passive operation with no emitted signals. STELION is inherently covert — it cannot be detected, tracked, or targeted through its navigation emissions.

04

Denied Environment Ready

High reliability in denied and degraded environments, urban canyons, tunnels, polar regions, and contested battlespaces where GNSS is compromised.

05

Drop-In Resilience Layer

Enhances resilience when integrated with existing systems. STELION augments INS, GNSS, and other navigation layers without replacing current infrastructure.
