If the GPS receiver temporarily loses satellite tracking, the RF-B! transmitter controller
operates in a FREERUN mode. During a loss of satellite tracking, the error log is updated with
the error message <E_GPS_NOT_TRACKING_SATELLITES> and is indicated by a Simulcast
Manager state 5.

In the FREERUN mode the timing accuracy for the station depends on the accuracy of the
reference oscillator. The reference oscillator can maintain simulcast accuracy for 96 minutes.
After 96 minutes, the station is disabled from paging until satellite tracking resumes. While
paging is disabled, the error log is updated with the error messages <S_PAGING_DISABLED>
and <E_SASM_FREERUN_TIMEOUT>
. To get more information about the GPS receiver status
and why GPS tracking was lost, perform the following steps:
