1. Tracking sensitivity: the minimum GNSS signal power at which the module can maintain lock (keep
positioning for at least 3 minutes continuously).
2. Reacquisition sensitivity: the minimum GNSS signal power required for the module to maintain lock
within 3 minutes after loss of lock.
3. Cold start sensitivity: the minimum GNSS signal power at which the module can fix position
successfully within 3 minutes after executing cold start command.
