Synchronization-Free Method Locates LEO Satellites With Median Accuracy of About 31.41 km in Scientific Reports
Scientific Reports published a study on three-dimensional localization of Low Earth Orbit satellites on November 13, 2026, presenting a synchronization-free method using a network of distributed passive ground antennas. The method combines improved relative Received Signal Strength measurements with Apollonius circle geometry, and leverages a multi-stage dimensionality reduction technique to enhance the precision of target estimation in multi-receiver systems. Theoretical results demonstrate that the method achieves a 3D positioning median accuracy of approximately 31.41 km and a 3D angular error of 6.55 degrees over 200 Monte Carlo trials, with randomly distributed satellite positions spanning altitudes from 100 to 500 km. The authors noted that these performance levels are attained without the need for inter-receiver synchronization, complex hardware, complex computational burden or prior knowledge of satellite ephemeris. The paper, by Mohammadreza Khorshidi, Hossein Samimi, Roghieh Karimzadeh Baee and co-authors, carries DOI 10.1038/s41598-026-79782-7. It was received on September 5, 2026, accepted on November 3, 2026 and published on November 13, 2026.
