0x83 Report Packet 83
Double-precision XYZ Position Fix And Bias
Information
This packet provides current GPS position fix in XYZ ECEF
coordinates. If the I/O "position" option is set to "XYZ ECEF" and
the I/O double-precision option is selected (packet 35), the receiver
sends this packet each time a fix is computed. The data format is
shown below.
The time-of-fix is in GPS time or UTC, as selected by the I/O
"timing" option in packet 0x35. At start-up, if the I/O double-
precision option is selected, this packet is also sent with a negative
time-of-fix to report the current stored position.
Packet 42 provides a single-precision version of this information.
