Direct-to-Cell Satellite Communication Using Standard 5G Waveforms

Handling massive Doppler frequency shifts (up to ±48 kHz) and round-trip propagation delays exceeding 20 ms inside automotive telematics baseband processors without breaking 5G HARQ timing.

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.
