Simrad EM3000 (Heading) - 05

Description

Driver to be used to decode roll-pitch-heave observations from motion reference units, outputting data in the Simrad EM1000 or EM3000 format.

Note that the UDP driver timestamps data on arrival, as there is no timestamp in the format.

These drivers should not be used on objects that require accurate timestamped motion data, for instance, in combination with a multibeam system.

Decoding Notes

For both message types the status field is used to set the quality indicator.
For the EM1000 message the quality indicator is set to 1.00 when a 00h byte is encountered.
For the EM3000 message the quality indicator is set using the following table:

Status Byte	Quality Indicator
90h	1.00
91h – 9Fh	+1.10 to +2.50 (step size 0.10)
A0h - AFh	-1.00 to -2.50 (step size 0.10)

Drivers IO Notes

Command line parameters "EM1000" and "EM3000" indicate the message type as being decoded.
Otherwise, the first incoming byte is time-tagged.
