Astro-inertial navigation without GNSS

A new era for autonomous navigation

MAGELLAN is an innovative navigation system that combines heavenly recognition automated and inertial unit high precision. Designed to provide reliable, signal-independent positioning GNSS (GPS, Galileoetc.), it has established itself as a benchmark solution for navigation in contested or degraded environments.

Based on inertial navigation technology, MAGELLAN replaces conventional GNSS recalibration with astral recalibration, using the stars at night and the sun during the day. This ingenious principle is based on inertial data:

  • High performance
  • High frequency
  • Permanent availability
And to correct the drift error inherent in this integral technology by injecting astral data. The result is an availability rate of 100%.

Key features

Navigation without GNSS

MAGELLAN allows you to determine a precise position, day or night, without the need for a visible horizon or human intervention. It is totally independent of satellite positioning systems, guaranteeing safe navigation in the event of jamming, decoys or signal loss.

Automated sextant mode

Thanks to an intelligent camera and star-recognition algorithms, the device automatically identifies visible stars and calculates the geographical position without the need for astronomical knowledge or nautical tables.

Astro-Inertial mode

MAGELLAN incorporates an inertial unit calibrated in real time by celestial observation. This mode ensures continuous position tracking, even without sky sighting, with periodic recalibration to maintain accuracy.

Benefits

Navigation without GPS (strategic independence)

Allows you to locate yourself by observing the stars (sun, moon, stars, planets) day and night, offering total autonomy from radio signals and satellites.

Vital in case of jammingof malice or GNSS signal destruction during major conflicts.

MAGELLAN combines stellar and solar sighting with inertial navigation: two mature technologies that deliver a restitution of position and attitudewith no need for manual pointing or astronomical knowledge.

The precision of MAGELLAN contains the error within a 200m envelope, whatever the mission duration.

The technology astro-inertial provides an availability rate of 100%.

The need for secure navigation is just as prevalent in the transport sector as it is in the industrial sector. civil of goods and people than for missions military crucial.

The military was a forerunner in development, initially designed for operational needs, Magellan is, nonetheless, suitable for civilians. In recent years, the international context has seen an increase in the number of areas affected. In 2024, more than 46,000 European civil flights were disrupted by failures in their flight control systems. geolocation satellite.

Developed through programs innovation support (RAPID-DGA, Région Normandie, NATO-DIANA), MAGELLAN is a system that has been extensively tested and experimented under a wide range of conditions and on a wide range of carriers (ships, aircraft, UAVs). MAGELLAN is available in a naval and a aerial. The naval version can be integrated on a ship without structural modification. The Aero version can be integrated without modification on the C130 or theATL2in place of the old manual sextant.

Designed, assembled and calibrated locally in Normandy (Bretteville-sur-Odon), Starnav is certified ISO 9001 and EN 9100.

STARNAV, a leading-edge technology SME, has been selected by the highly competitive acceleration program DIANA (Defense Innovation Accelerator for North Atlantic) in 2025.

Magellan's story

Premises

Originating in the earliest ages of human knowledge, astral navigation remained unchanged for centuries. Admiral Desclèves describes precisely how this knowledge was used and transmitted among the peoples of Oceania in the book " the people of the ocean" published by l'Harmattan

Sextant G-Stell

STARNAV drew on its expertise in the field of autonomous astral navigation to launch the development of the G-STELL SEXTANT (stellar georeferencing): a system for determining the user's position by observing the Sun, Moon, planets and stars.
