Flight-Proven GNSS for LEO

With U.S.-Based Engineering Support

JAVAD GNSS delivers GNSS receivers and antennas with flight heritage for LEO satellite missions, backed by US-based engineering support from integration through launch.

When questions come up, you get our engineers, not a support ticket queue. That's what "in-house" means to us.

Not Just Documentation

Engineering Partnership

Most GNSS vendors hand off an ICD and leave you to figure it out. We work differently. Our engineering team is available throughout your mission, from first integration questions through launch day and beyond.

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.

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.
