Bits 27-28 are reserved for the output interface in the normal way.
The selective availability model was derived from de-biased empirical data that
includes Gaussian and time correlated noise (excluding the receiver clock
Gaussian noise). When this error source is activated (MS_GP_ER bit 1 set) all
the remaining satellite noise sources are automatically de-activated.
