Optical atomic clocks offer the potential for a new era of timekeeping, with laboratory systems at the world’s leading NMIs already demonstrating 100x improvements in accuracy compared with the microwave fountain clocks that offer the best realisations of the SIsecond. Enhanced PNT systems with these next-generation clock technologies could facilitate GNSS constellations with significantly-…
M3 Systems has successfully provided GNSS test solutions since 2013 with its STELLA NGC (Radio Frequency Constellation Simulator) and STELLA RP (Record and Playback) products. However, evolving technological advancements in GNSS signals, positioning services (OSNMA, HAS, EWSS), LEO-PNT, and other positioning sensors (e.g., IMU) now require more flexible, modular, and advanced testing capabilities.…
NAVSHIELD adds efficient and advanced protection to Position, Navigating, and Timing (PNT) already developed systems or future missions, including GNSS (Global Navigation Satellite Systems), LEO-PNT, terrestrial PNT, and inertial navigation. These systems are essential for critical applications in infrastructure, telecommunications, defence, and transport. However, their vulnerability to…
Today any safety critical application needs to improve its position and navigation performance in terms of integrity and resilience to disturbs.
MEDEA project target is the development of an “applique” antenna equipment suitable for commercial and professional GNSS receiver to be adopted by users providing additional integrity to PNT solution being able to detect and mitigate potential…
The increasing reliance on Global Navigation Satellite Systems (GNSS) and Satellite-Based Augmentation Systems (SBAS) like EGNOS for aviation navigation has highlighted the critical need for robust performance monitoring and interference mitigation. While EGNOS V2 has significantly improved GNSS accuracy and integrity in European aviation, its evolution to EGNOS V3 will bring dual-frequency,…
Real-time S-GNSS® receiver
This project is to design and build a real-time SDR (software defined receiver) enabled with Supercorrelation™ technology. This S-GNSS receiver can provide increased accuracy, sensitivity and reliability compared to standard GNSS receivers. Supercorrelation measures satellite signals based on angle-of-arrival, enabling rejection of unwanted signals from…
Following the Dutch studies on GNSS vulnerabilities IKUS-I and IKUS-II, it was found that GNSS knowledge within organizations from the Dutch Critical Infrastructure sectors requires to be deepened and distributed. To protect Critical Infrastructure during their operations, there is a clear need to be aware of what GNSS is, what the dependencies including the risks are for an organisation and how…
The EL1-106 MAGIC aims to address the development of a TRL 6 antenna array navigation receiver prototype, enabling PNT solutions in the C-band frequency, using the coming LEO- PNT IoD C-band signals.
The main objectives for this activity are:
Develop a receiver with C-band signal processing capability (up to high signal-bandwidth)
Extend the receiver processing to support ESA LEO-PNT…
PASQUALE (Precise and Stable Navigation with Quantum Accelerometer) aims at advancing next-generation positioning, navigation and timing (PNT) technologies. The project explores the integration of quantum inertial sensing with conventional GNSS and inertial systems to enhance navigation accuracy and robustness, particularly in GNSS-degraded or denied environments.
At its core, PASQUALE develops…
GNSS is the only global, free, comprehensive technology providing absolute PNT data to users worldwide. Its limitations are known, including long life cycle and replenishment schedule, affecting their ability to adapt easily to short-term market needs and to some extent, resilience.
Considering the above, alternative PNT methods and solutions have been developed or are being investigated,…
