GNSS Performance Where Failure Is Not an Option

Low Earth Orbit presents a challenging navigation environment. High orbital velocities, radiation exposure, increasing signal interference, and long mission lifecycles demand GNSS solutions purpose-built for space and not adapted from terrestrial systems.

The TR-2S LEO is engineered to deliver reliable navigation performance under these conditions, supporting modern commercial and government space missions.

Engineered for Reliable GNSS Operation in Orbit

Rad-Hardened-JAVAD

Radiation-Tolerant, Space-Hardened Design

Engineered to maintain continuous GNSS operation in the radiation environment of Low Earth Orbit.

Position, Navigation, & Timing for Space Systems

 

  • LEO observation satellites

  • Commercial and government constellations

  • Formation flying missions

  • Launch vehicle upper stages

  • High-dynamic space platforms

Precise Orbit Determination (POD)

High-accuracy GNSS observables enable precise satellite position and velocity estimation in real time and through post-processing.

PVT (Position, Velocity, Time)

Provides continuous position, velocity, and timing outputs to support onboard navigation, guidance, and spacecraft subsystems.

Moving Base & Relative Navigation

Enables relative positioning between satellites or reference objects for formation flying, rendezvous, and coordinated operations.

Time Synchronization

GNSS timing supports synchronization of onboard subsystems, payload operations, and inter-satellite activities.

European Space Agency (ESA) Vega Mission

JAVAD OEM Board Guides ESA Vega Mission

A JAVAD OEM GNSS board is at the heart of the navigation system of the Vega space vehicle developed by the European Space Agency (ESA). ESA developed Vega to launch small satellites into low Earth orbit.

It provides great flexibility of mission at an affordable cost and represents the European solution for space accessibility.

Gruyère Space Program Pave Space

High Precision and Stability with JAVAD

The success of Colibri’s flights hinged on reliable navigation and control systems.

The JAVAD GNSS TR-2S consistently maintained a 1cm fix throughout Colibri’s 100-meter flight, despite the harsh vibrations and dynamic flight conditions.
