0x43 Report Packet 43
Velocity Fix, XYZ ECEF Report
This packet provides current GPS velocity fix in XYZ ECEF
coordinates. If the I/O "velocity" option (Packet 35) is set to "XYZ
ECEF ", and the packet is masked for output by packet 8E-4D, then
the GPS receiver sends this packet each time a fix is computed if
selected by the I/O "timing" option. The data format is shown below.
The time-of-fix is in GPS time or UTC as selected by the I/O "timing"
option.
