Com
m
and
s
For a given channel expecting more than one block of data, when one of them is not
yet available, its warning flag is set to 7 and the rest of the block is zeroed out.
PBN: Enable/Disable PBN Message
$PASHS,RAW,PBN,x,s
Enable/disable position data (PBN) messages on port x, where x is the output port,
and s is ON or OFF.
Example: Enable PBN on port B
$PASHS,RAW,PBN,B,ON
$PASHQ,PBN,x
The associated query command is $PASHQ,PBN,x . This command outputs one
PBN position data response message on port x, where x is the optional output port.
double 8 Full carrier phase measurement in cycles. Not available unless
carrier phase option is installed.
double 8 Raw_range. Raw range to satellite in seconds. Computed by
formula: receiver time - transmitted time. NOTE: If TSC is set to
GPS, in GLONASS pseudoranges, due to 11-sec (currently)
difference between GLONASS system time and GPS system
time, raw range will have 11-sec integer part. If TSC is set to
GLO, in GPS pseudoranges, due to 11-sec (currently) difference
between GPS system time and GLONASS system time, raw
range will have –11 sec integer part.
long 4
Doppler (10
-4
Hz)
long 4 Smoothing.
Bits 0-23-smooth correction
Bit 23 (MSB) - sign
Bits 0-22 - magnitude of correction (centimeters)
Bits 24-31 - Smooth count, unsigned, as follows:
0 - unsmoothed
1 - least smoothed
100 - most smoothed
unsigned char 1 Computed by XORing all the bytes of the structure. (MCA only)
total bytes 37 C/A only
