LeoRx Reference Receiver

Product Information

Accelerate Next-Generation LEO PNT Research

Septentrio’s LeoRx is a high-performance multi-frequency GNSS reference receiver designed for organisations at the forefront of LEO PNT research and development. Supporting both traditional MEO GNSS constellations and Xona’s X1 and X5 LEO PNT signals, LeoRx enables engineers, researchers and system developers to evaluate emerging positioning technologies with exceptional precision and confidence.

Designed for the earliest stages of Xona signal availability, LeoRx delivers industry-leading measurement quality with ultra-low noise and cycle slip performance, while continuously monitoring and mitigating interference, multipath and challenging environmental conditions. The result is more reliable data, faster development cycles and greater confidence in system performance.

Available in limited quantities, LeoRx provides early access to next-generation LEO navigation technology, helping organisations prepare for the future of Resilient Positioning, Navigation and Timing (RPNT).

Explore the Future of Resilient Positioning

LeoRx combines comprehensive support for today’s GNSS constellations with advanced processing of tomorrow’s LEO PNT services. Alongside all major MEO GNSS signals, the receiver supports demodulation and decryption of Xona X1 and X5 signals, providing an ideal platform for signal evaluation, algorithm development and performance testing.

Whether developing new navigation applications or validating resilient PNT technologies, LeoRx gives engineers the insight needed to understand and exploit the benefits of low Earth orbit navigation.

Maintain Accuracy in the Most Challenging Environments

GNSS+ Technologies with IONO+

Space weather and ionospheric disturbances can degrade GNSS performance, interrupt RTK positioning and even result in complete signal loss. LeoRx incorporates IONO+, an advanced technology developed from years of experience supporting GNSS applications in some of the world’s most ionospherically active regions.

IONO+ continuously monitors ionospheric conditions and helps maintain positioning performance when conventional GNSS receivers struggle, giving users greater availability, improved accuracy and enhanced operational resilience.

Advanced Anti-Jamming and RF Spectrum Awareness

AIM+ Interference Detection and Mitigation

Reliable positioning depends on reliable signals. LeoRx features Septentrio’s AIM+ intelligent anti-jamming and RF spectrum monitoring system that continuously detects, analyses and suppresses both intentional and unintentional interference.

AIM+ automatically mitigates a broad range of RF threats, including:

• Continuous narrowband jammers
• Wideband interference
• Pulsed transmitters
• Inmarsat transmissions
• Iridium satellite communications

By actively protecting the GNSS signal environment, AIM+ enables high-precision positioning even in complex and RF-congested operating environments.

Powerful Tools for Signal Analysis and Development

LeoRx is supplied with the comprehensive RxTools software suite, giving engineers everything needed to analyse, visualise and evaluate LEO PNT signals and their associated data.

An intuitive browser-based interface also provides powerful monitoring and visualisation of MEO GNSS signals, allowing users to compare, analyse and validate performance across multiple satellite constellations from a single platform.

Whether conducting laboratory research, field trials or algorithm development, LeoRx delivers the data quality and analytical tools required to accelerate innovation.
