Appendix 03 - 3
Each satellite has three separate clocks on board (one in use and two standby) and in the event of the
total failure of a satellite, one of the spares already in orbit can be manoeuvred into position within a
few hours.
The only time the DoD can predict there may be a substantial break in coverage for civilian users, is at
a time of National Emergency, when the whole system may be reverted to P code (military) operation
only, for strategic reasons.
Having said this, the system remained fully available to civilian users during the Gulf conflict.
