13.4. AUTEC Range Data
The Range data file format is the RAO used by AUTEC to pass data to PC Argos. The data file contains data in the following format:
??_A01451200_-124.20_36935.19_-133.40_6.58_-4.15_6.15_-9.04_1.08_1.04
??_B02451200_-123.20_36235.19_-143.40_6.58_-4.15_6.15_-9.04_1.08_1.04
??_A01451201_-164.20_36935.19_-137.40_6.58_-4.15_6.15_-9.04_1.08_1.04
??_B02451201_-134.20_36335.19_-133.40_6.58_-4.15_6.15_-9.04_1.08_1.04
 | Note, spaces in the above sample have been replaced by underscores. |
The file contains one line of text for each position fix for the exercise participant, and each file may contain data for more than one participant.
The columns of data represent the following:
Table 13-3. Columns in AUTEC range data
Field |
Description |
|---|---|
|
?? |
Header for each row |
|
AO1 |
Unique (3 letter) identifier for track |
|
451200 |
Hours Minutes Seconds of position fix (note that there is not a space between the track identifier and the start of this part of the record |
|
It is important that the above two fields are positioned adjoining each other in the datafile. The remaining fields in the line may be any size, but they must be separated by white space. | |
|
-124 36945.19 -123.39 |
x, y, z in yards from the range origin |
|
6.58_-4.15_6.15 |
x,y,z velocities in yards per second |
|
-9.04_1.08_1.04 |
z,y,z accelerations in yards per second per second |
| Note that only the x,y,z positions from the data are used in Debrief; the velocities and accelerations are ignored. |
 | The data file format does not contain course and speed data, so these are calculated using the range and bearing from the previous point, together with the time difference. This gives values of course and speed calculated as over the ground; which obviously is not the through-the-water values the participants will be experiencing. |
