interval: default PVT output rate (see 4.1.8)
This block contains the integrity statistics that are computed by the receiver RAIM algorithm.
The output of the RAIM algorithm contains integrity information, which can be used in
user applications. First, the RAIM algorithm generates its own integrity flag based on the
probability of false-alarm, which can be used by a user as a receiver-level indication of
positional integrity. If the internal integrity test is successful, a user has an opportunity to
introduce a more stringent application-specific integrity criterion by using External Reliability
Levels (XERL). The positional solution is deemed as passed an application-level integrity
test if the XERLs are within user-defined (and application-dependent) alarm limits. This
comparison (and the definition of alarm limits as well) takes place in a user application and
is outside of the receiver scope. Please also refer to section 2.7.
