Raw Data Commands
XYZ: 3D Satellite Positions
$PASHS,RAW,XYZ,c1,s2,[f1]
This command enables or disables the 3-dimensional satellites position messages,
where c1 is port A, B or C (optional port), s2 is ON or OFF, and f1 is the optional
numeric output interval setting supporting a range of 0.05 to 999 seconds,
depending on the measurement update rate option installed.
$PASHQ,XYZ,c1
This command allows you to query the three-dimensional position for each tracked
satellite, where c1 is the optional output serial port. If a port is not specified, the
receiver sends the response to the current port.
$PASHR,XYZ
In addition to satellite positions, the XYZ message also contains the time at which
the satellite signals were received and a pseudo-range value which has been
corrected to eliminate atmospheric delays and uncertainties resulting from the
differences in velocity between the DG16 and the satellites (relativistic errors).
The XYZ message is output in the format below:
$PASHR,XYZ<Satellite position data string + checksum>
char 1 wn—Week number in GPS time scale when SBAS
ephemeris was received.
char 1 Satellite number (33 to 64)
unsigned
short
2 Checksum computed by breaking the structure into
40 unsigned shorts, adding them together and taking
the least significant 16 bits of the result.
Total Bytes: 70 (83 when include header and <CR><LF>
