Enhancing 5G NTN VSAT RACH in GNSS-Denied environments
The 3GPP 5G non-terrestrial networks (NTN) technology fundamentally relies on a global navigation satellite system (GNSS) fix at the user equipment (UE) to pre-compensate for user-link delay and Doppler shifts prior to any transmission, including the random-access procedure for initial access. In GNSS-denied or interfe...
