Each record consists of numbers on ASCII format separated by spaces and terminated
by carriage return and linefeed (values 10 and 13). Leading spaces are used, so the
numbers are separated by two or more spaces, and spaces may occur before the first
number on the record.
Time is counted since last midnight UTC time. Heading is true heading from the GNSS
phase measurement, which is not the same as the heading output on the other formats.
Gyro heading is from an external gyro, 0.00 if no gyro is connected. Baseline is the
slant range between the antenna centres from the GNSS phase measurement. Height is
the height difference between the antennas from the GNSS phase measurement. Height
is positive if antenna 1 is above antenna 2.
The data are intended for calibration of the antenna installation, so no data are output
unless the GNSS phase measurements are valid.
A.5 Echo sounder format 9
This echo sounder format is a proprietary ASCII text format with fixed-length records
used when connecting Simrad EA500 and other echo sounders.
Format:
Element Columns Scaling Format
Header 1 – 7 :000000
Heave 9 – 13 1 cm sdddd
Warning 14
space or “?”
Roll 15 – 19 0.01 degree sdddd
Pitch 21 – 25 0.01 degree sdddd
Term 26 – 27 CR-LF
Heave is positive up. Roll is positive with port side up. Pitch is positive with bow up.
The zeroes in the header occupy the columns used for acceleration when this fomat is
output from other systems. Seapath does not output acceleration.
“s” is the sign character, space if positive and “-“ if negative. “dddd” is a decimal
number with leading zeroes where appropriate. The warning charater is space if data are
normal, “?” if data are invalid or of reduced quality.
Columns between elements are filled with spaces.
The definition of the attitude angles in this format is different from the Euler angles
definition used elsewhere. The difference appears in the roll angle, where:
