This command allows you to set parameters for the user defined datum and store
them in battery-backed memory. Use this command with the $PASHS,DTM,UDD
command, described on page 61. Table 4.45 lists the parameters.
$PASHQ,UDD,[c]
This is the associated query command, where c is the optional output port. If a port
is not specified, the receiver sends the response to the current port.
The response message is in the format:
$PASHR,UDD,d1,f2,f3,Dx,Dy,Dz,ex,ey,ez,f4
18 B Satellite NOT used because of bad URA (or some accuracy problem indicated in
navigational data)
17 Z Satellite NOT used because marked 'unhealthy' in almanac
16 D Satellite NOT used because differential corrections are old or invalid
15 J Satellite NOT used because big code outlier was detected
14 R Satellite NOT used because RAIM or some other algorithm detected a
pseudorange bias
13 I Satellite NOT used because satellite disabled by external command SVP,USP)
12 L Satellite NOT used because Signal To Noise Ratio is less than Mask
11 G Satellite NOT used because it's possibly a ghost satellite
10 V Satellite NOT used because computed satellite coordinates are suspicious
09 N Satellite NOT used because satellite true number unknown (for modes, where we
need the true satellite number
08 K Satellite NOT used because it was disabled by RTK engine (N/A in G12)
02 O Satellite NOT used because of some other case
01 E Satellite NOT used because no navigational data (ephemeris) is available
