call processing because of MSO or QHSO backup. However RGPS head downtime
will occur . And alarms will be reported.
A failed RGPS head should be replaced immediately after failure detection and
within the applicable MSO/QHSO backup time period (i.e., up to 8 hours MSO and
up to 24 hours QHSO).

30 minutes for the replacement RGPS head to successfully track and acquire satellites.
