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.
