54 G12 OEM Board & Sensor Reference Manual
This command is available for G12 extended memory only.
Example
Enter the following command to set RAIM mode to terminal mode.
$PASHS,AIM,TER<Enter>
$PASHQ,AIM,[c1]
The associated query command displays the RAIM configuration, where c1 is the
optional port designator for the output of the response. If a port is not specified, the
receiver sends the response to the current port.
The response message is output in the format:
$PASHR,AIM,a,s,[s1,s2,...,si]
Table 4.4 defines the response format.
ALT: Ellipsoidal Height
$PASHS,ALT,f1
This command allows you to set the ellipsoidal height of the antenna, where f1 can
be any value from -99999.99 to +99999.99. The G12 uses the altitude value set
through this command when it is computing 2D positions.
DEFAULT SETTING
AIM—OFF
Table 4.4. AIM Response Message
Parameter Description
s Current RAIM mode (3 characters)
• OFF— RAIM is off.
• NPA— RAIM is set to non-precision approach. The alarm limit is 0.30 nmi.
• TER— RAIM is set to terminal. The alarm limit is 1.00 nmi.
• ERT— RAIM is set to en route. The alarm limit is 2.00 nmi.
• s can also be defined as an alarm limit in the format n.nn from 0.015 to 4.00 nmi.
d The number RAIM returns
• 0— No errors detected.
• 1— Error is detected and successfully corrected.
• 2— Error is detected and correction is impossible.
• 3— Detection is not available for either a lack of satellites or poor geometry.
• 4— Error is detected and the rest of the satellite set is not available.
s1, s2, ..., si Represents a pair of excluded/detected channel and corresponding satellites as n-m string
where n is channel number excluded/detected and m is corresponding satellite number.
