120 GG Surveyor GPS+GLONASS Reference Manual
$PASHR,PBN
The response is a binary message output on every recording interval (RCI). The
message is in the form:
$PASHR,PBN,(position structure)
where Table 6.35 defines the measurement structure.
RAW: Setting Query Command
$PASHQ,RAW,x
Show current settings of raw data parameters, where c is the optional output port.

Field Bytes Content
long rcvtime 4 Signal received time in milliseconds of week of GPS system time
or in milliseconds of week/day of GLONASS system time (see
commands $PASHS,TSC and $PASHS,SYS for more
information). If GLONASS system time scale is chosen,
operation (rcvtime % day) produces GLONASS system time (a
time within a day) in all cases. This is the time tag for all
measurements and position data.
char sitename 4 Set to user-entered string or four question marks ???? if empty
double navx 8 Antenna position ECEF x coordinate in meters.
double navy 8 Antenna position ECEF y coordinate in meters.
double navz 8 Antenna position ECEF z coordinate in meters.
float navt 4 Receiver clock offset in meters.
float navxdot 4 The antenna x velocity in meters per second.
float navydot 4 The antenna y velocity in meters per second.
float navzdot 4 The antenna z velocity in meters per second.
float navtdot 4 Receiver clock drift in meters per second.
unsigned short
PDOP 2 PDOP multiplied by 100.
unsigned short
checksum 2 The checksum is computed by breaking the structure into 27
unsigned shorts, adding them together, and taking the least
significant 16 bits of the result.
