Empowering the Tracking Performance of LEO-Based Positioning by Means of Meta-Signals

Global Navigation Satellite Systems (GNSSs) are the most widespread technology for Position and Timing (PNT). They have been traditionally deployed exploiting Medium Earth Orbit (MEO) or Geosynchronous (GSO) satellites. To meet future demands overcome MEO GSO limitations, GNSSs based on Low (LEO) constellations investigated as a radical system change. Although characterized by higher Doppler effect, PNT service supplied LEO satellites can provide received signals that about 30 dB stronger. Moreover, broadband forthcoming mega-constellations be exploited to deliver piggybacked service. With this cost-effective solution, might subject substantial bandwidth limitations. A narrowband implementation of so-called meta-signal approach in GNSS receivers, namely Virtual Wideband (VWB), tolerate harsh conditions while reducing processed bandwidth. It is thus suited secondary delivered The aim work show applicability VWB architecture provided service, hosted mega-constellation. Through case study we demonstrate capability bear high empowering potential PNT.
