Hybrid Monostatic and Bistatic Sensing for Target Localization in OFDM Systems under Phase Noise
Lucía Pallarés Rodríguez, Musa Furkan Keskin, Alireza Pourafzal +3
In hybrid monostatic-bistatic orthogonal frequency-division multiplexing (OFDM) sensing, each sensing node receives a superposition of monostatic and bistatic target returns, whose…
Coordination of Ground-to-Space Reference Networks for High-Precision GNSS
Xue Xian Zheng, Xing Liu, José A. López-Salcedo +2
High-precision Global Navigation Satellite System (GNSS) services rely on accurate orbit, clock, atmospheric, and hardware-bias corrections generated from reference observations. T…
Optimal Placement of Movable Antennas for Angle-of-Departure Estimation Under User Location Uncertainty
Lucía Pallarés-Rodríguez, Angelo Coluccia, Alessio Fascista +4
Movable antennas (MA) have gained significant attention in recent years to overcome the limitations of extremely large antenna arrays in terms of cost and power consumption. In thi…
LEO Constellations as a Decentralized GNSS Network: Optimizing PNT Corrections in Space
Xing Liu, Xue Xian Zheng, José A. López-Salcedo +2
With the rapid expansion of low Earth orbit (LEO) constellations, thousands of satellites are now in operation, many equipped with onboard GNSS receivers capable of continuous orbi…
