Direkte Satellitenkommunikation zum Fahrzeug mittels 5G-Standard-Wellenformen

Kompensation massiver Doppler-Verschiebungen (bis ±48 kHz) und Signallaufzeiten >20 ms in Telematikmodems ohne Verletzung der 5G-HARQ-Zeitraster.

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.
