Why Stellar Navigation?

01

Independent of GNSS

Continue navigating confidently when satellite signals are unavailable or compromised.

02

Resistant to Jamming & Spoofing

Celestial reference points cannot be manipulated by electronic attack, providing an additional layer of navigation resilience.

03

High Precision

Accurate attitude and positioning information for demanding operational environments.

04

Mission Ready

Designed for integration across defence, security and autonomous platforms.

Technology

Introducing Stellar Navigation

Stellar Navigation is an advanced navigation technique that determines position and orientation by observing celestial bodies. Unlike satellite-based navigation systems, stellar references cannot be jammed, spoofed or switched off, providing an independent source of positioning information.

By combining precision optics, inertial sensing and advanced navigation algorithms, Stelion delivers a resilient positioning solution capable of supporting operations where GNSS cannot be relied upon.

Our technology is engineered for modern defence and security applications where operational assurance is paramount.
