RxControl: Navigation > Receiver Operation > Position > Integrity
Use these commands to define/inquire the parameters of the Receiver Autonomous Integrity
Monitoring (RAIM) algorithm in rover PVT mode.
The
Mode
argument acts as an on/off switch: it determines whether RAIM is active or not.
The
Pfa
argument sets the probability of false alarm of the w-test used in the "identification"
step of the RAIM algorithm. Increasing this parameter increases the integrity but may reduce
the availability of the positional solution.
The
Pmd
argument sets the probability of missed detection, which the receiver uses to com-
pute the Minimal Detectable Bias and hence the XERL values.
The
Reliability
argument sets the probability of false alarm of the Overall Model test used in
the "detection" step of the RAIM algorithm.
The value to be provided in the
Pfa
,
Pmd
and
Reliability
arguments are the base-10 logarithms
of the desired probabilities. For instance, if you want a probability of false alarm of 1e-6, you
have to set the
Pfa
argument to -6.
Note that this command has no effect when the receiver is configured in static PVT mode
with the
command. In static PVT mode, the RAIM algorithm uses
fixed parameters that cannot be changed by the user.
Examples
To configure the receiver outlier detection with a probability of 1e-4 (0.01%) that a false alarm
will be raised (type I error), a probability of 1e-4 (0.01%) that an outlier will be missed (type II
error) and an Overall Model probability of false alarm of 1e-6 (0.0001%), use:
COM1>
srl, on, -4, -4, -6 <CR>
$R: srl, on, -4, -4, -6
RAIMLevels, on, -4, -4, -6
COM1>
To disable the outlier detection, use:
COM1>
srl, off <CR>
$R: srl, off
RAIMLevels, off, -4, -4, -6
