The word-wrapping appearing in the above examples appears because of

the constraints of margins used in this presentation. Interpret each record as

a single string lacking any carriage return/line feed breaks.

9.10.2 Interpreting Telemetry Data Going to a File

Generic telemetric data going to a file is output in the following form as a

single string:

Day Month Year Hour Minute Seconds Nav_Y_position

Nav_X_position heading pitch roll speed depth altitude

range_scale Aux(1) Aux(2) Aux(3) Aux(4) Aux(5) Aux(6)

Event_# Magnetometer_X Magnetometer_Y Magnetometer_Z

Again, space considerations in this document force us to show the string on

multiple lines.

Note: Underscores are used above to join words together when two or

more words represent a single string; white space delimits the variables.

The altitude is usually derived from towfish telemetry. If bottom track is

enabled, then altitude comes from bottom-tracking. Range-scale comes

from the first channel.

Table 9-6 shows sample output (two records), captured to a

file.
