Note: POS MV sends records using the Simrad 3000 format at an update rate from one to 200 Hz; TOV is updated
at the same rate. The recommended minimum baud rate for use with this format is 19200 baud at 100 Hz.
TSM 5265 Format
You can use this format with the Thompson TSM 5265 multibeam sonar. The output message
supplies the sonar with a time tag (roll, pitch and heave), heading and sonar velocity. POS MV
updates the message and the TOV from one to 200 times per second.
The message is a 24-byte data string with the following format.
• Header: 90 hex
• Time tag: double precision float, UTC time in seconds of the week
• Roll format: 2's complement, LSB = 0.01°, roll sense is user selectable from the MV-
POSView Controller program
• Pitch format: 2's complement, LSB = 0.01°, pitch sense is user selectable from the
MV-POSView Controller program
Heave format: 2's complement, LSB = 1 cm, heave sense is user selectable from the
•
MV-POSView Controller program
• Heading format: LSB = 0.01°, 0 to 359.99°, positive = clockwise
• Longitudinal velocity format: 2's complement, LSB = 0.1 cm/s, positive = forward
• Transverse velocity format: 2's complement, LSB = 0.1 cm/s, positive = starboard
• Down velocity format: 2's complement, LSB = 0.1 cm/s, positive = down
The recommended minimum baud rate for use with this format is 38400 baud at 100 Hz.
You can use the MV-POSView Controller program to change the sense of the roll, pitch and
heave outputs. You can also select the TSS or the Tait-Bryan convention of rotations for the
