Positioning Packet

Using outputs from onboard gryrometers and 2‐axis accelerometers, orientations shown below in Figure B2, the positioning ethernet Packet provides motion data (rotational and acceleration) for the stationary base of the HDL‐32E unit. See the User Datagram Protocol (UDP) Positioning Ethernet Packet Format: HDL‐32E, Figure B3, for interpretation of data output.
