MULTIPLE REDUNDANT GNSS SYNCHRONIZATION SYSTEM

摘要

Methods and apparatus are provided for multiple redundant global navigation satellite system GNSS synchronization of a plurality of base stations via a system node that is in communication with the plurality of base stations. At the system node, time information is provided to and received from the plurality of base stations and a system time reference is generated based on at least some of the time information, such that the system time reference is synchronized with an external time epoch reference provided by the GNSS. If a base station is unable to receive the GNSS service, the system node provides time synchronization information to the base station to synchronize the base station with the system time reference, which itself is synchronized to the external time epoch reference provided by the GNSS service.
