The TR-2S LEO delivers high-precision GNSS positioning for Low Earth Orbit (LEO) missions.

Developed for customers requiring high-integrity navigation performance under the demanding conditions of space, the TR-2S LEO integrates radiation-tolerant, space-hardened electronics with patented spoofing & jamming detection to support, secure, and protect continuous GNSS operation. The board tracks 874 channels across all major GNSS constellations, enabling robust PVT solutions with multi-frequency resilience.

JAVAD GNSS brings more than two decades of flight heritage, with OEM boards deployed on a majority of commercial launch vehicles worldwide, including ESA’s Vega program. The company continues to build upon its experience now with focused concentration on LEO-based applications with technologies like the TR-2S LEO and the SpaceAnt-G3T OEM GNSS antenna. The SpaceAnt-G3T features a stable phase center and is usable for single, dual, and triple frequency applications.

“The TR-2S LEO reflects our dedication to providing mission-critical GNSS technology designed and manufactured in the United States,” said Bryson Gray, Director of Aerospace and Defense Solutions at JAVAD GNSS. “As commercial space accelerates, customers are looking for navigation solutions built on flight-proven performance, radiation tolerance, and the technical support needed to ensure mission success. That is exactly what we deliver.”

The TR-2S LEO is adaptable to a wide range of commercial launch vehicles, spacecraft, and high-dynamic applications.
