Communication Satellite Directe au Véhicule Utilisant les Formes d'Onde 5G Standards
Gestion des dérives Doppler jusqu'à ±48 kHz et des délais de propagation de plus de 20 ms dans les modems sans désynchroniser les timers HARQ du 5G.
Pre-Doppler Frequency Compensation
By tracking satellite ephemeris orbits in software, the vehicle shifts its uplink transmit frequency dynamically, landing signals perfectly centered in the satellite's receiver filter.
- Supports standard S-band and Ka/Ku-band NTN satellite connectivity.
- Doppler frequency shift compensation up to ±50 kHz at 2 GHz.
- Differential propagation delay estimation resolving up to 25 milliseconds.
- Seamless integration with Starlink, Kuiper, and OneWeb constellations.
