Over the centuries, people relied on celestial navigation, landmarks, and compasses to traverse vast distances. The advent of satellite-based Global Navigation Satellite Systems (GNSS) revolutionised positioning, navigation, and timing (PNT), providing an unprecedented level of ubiquitous positioning anywhere on or near the Earth surface. GNSS has long been woven into the fabric of our daily lives, becoming an indispensable utility, much like the internet or electricity. However, the growing dependence on GNSS has also highlighted its vulnerabilities, including susceptibility to radio frequency interference (RFI), such as jamming and spoofing, as well as signal degradation in urban and obstructed environments.</p> <p>To address these challenges, Low Earth Orbit (LEO) PNT constellations are emerging as a complementary and resilient navigation solution. Leveraging the advantages of increased satellite density, stronger signal power, and enhanced coverage, LEO PNT can offer improved performance in obstructed environments, faster convergence times, and greater resistance to RFI. These systems have the potential to enhance traditional GNSS services, support high-precision applications such as autonomous navigation and geospatial intelligence, and provide redundancy for critical infrastructures.</p> <p>As new LEO PNT services are developed, research and testing efforts will be essential to characterise their performance and integration with existing GNSS frameworks. Future developments in multi-GNSS fusion, interference mitigation, and precise orbit determination will further shape the evolution of navigation in the modern era.</p> <p>By leveraging advancements in satellite technology and ground-based augmentation, the 21st century promises a resilient and high-precision navigation ecosystem capable of meeting the growing demands of a connected world.</p> <h3><strong>Eldar Rubinov</strong><em>, PNT and Geodesy Technical Lead at FrontierSI</em></h3> <p><br /><strong> </strong><strong><img style="width: 77px; height: 91px; margin-left: 5px; margin-right: 8px; float: left;" src="/images/files/workshops/headshots/eldar-rubinov.jpg" alt="eldar rubinov" width="400" height="470" data-mce-width="77" data-mce-height="91" /></strong><strong>Eldar Rubinov </strong>is the PNT and Geodesy Technical Lead at FrontierSI, a not-for-profit research organisation in Australia.

In order to reduce the dependence on GNSS, great efforts have been made to investigate alternative Positioning, Navigation, and Timing (PNT) systems. The use of signals from Low Earth Orbit communications satellites as signals of opportunity for PNT (opportunistic LEO-PNT) is a promising approach for such an alternative PNT system.</p> <p>This work presents a computationally efficient algorithm that performs correlation-based estimations for Doppler shift of the synchronization sequence of Starlink broadband signals for use in opportunistic LEO-PNT. The performance of the algorithm is investigated through Monte Carlo simulations. The algorithm is shown to meet the modified Cramer-Rao bound (for the part of the signal used for estimation) for a signal-to-noise ratio greater than −8 dB in the absence of sample timing offsets. It further shows limited sensitivity to sample timing offset, making the algorithm also applicable to asynchronously sampled signals. A link budget analysis shows that the proposed algorithm requires a receiver antenna gain of at least 10 dBi to operate efficiently in practical applications using currently available Starlink signals.</p> <h3><strong>Winfried Stock,</strong><em> University of the Bundeswehr Munich Chair of Signal Processing</em></h3> <header> <h3><strong><img style="width: 77px; height: 91px; margin-left: 5px; margin-right: 8px; float: left;" src="/images/files/workshops/headshots/winfried-stock.jpg" alt="winfried stock" width="400" height="470" data-mce-width="77" data-mce-height="91" /></strong></h3> </header> <p><strong>Winfried Stock </strong>is a research assistant at the Chair of Signal Processing under Prof. Dr. Knopp. Over the past three years, he has rendered outstanding services in research and teaching, particularly in the fields of satellite communication, navigation and signal acquisition.</p> <p>The certificate of appointment was presented on 22.10.24 by Colonel Henkelmann in front of the staff of the Institute of Communication Systems and High Frequency Technology.
