5.4.1 Definition
GNSS Time Accuracy is the difference between the true GNSS time (reference time of the GNSS system) and the time computed by the GBLS System. For example, applications requiring synchronization of assets distributed across wide geographical areas can use GNSS time as a reference.

5.5.1 Definition
TTFF is the time taken by the GBLS to provide location-related data, starting either from the reception of a request, or from another triggering event (for instance for periodic or geo-dependent reporting). The TTFF is defined for a cold-start condition, defined as the GNSS receiver having: • no prior information; • in...
