12.2 GPS trace during scouting
Two GPS traces can be recorded (
outside of race
) when enabling the recording function.
To access this function, in the main menu, push the USB drive button
The recording
starts and the files are created when Trip1 is reset to 0
. A red point pictogram appears on the
screen.
The recording stops when stopwatch is armed (no need to trigger, just arm).
A more friendly stop function is to be
added to firmware.
The files are copied automatically in a USB drive when inserted, then archived (see later §). They can be visualized
and/or converted in different formats, for example with:
GPS Visualizer

12.2.1 Traces with fixed distance
It is a trace that records a point after driving a configurable distance. This distance gives the precision but also the
weight of the generated file. 10 m is a good compromise between accuracy and size.
In the
Recording
page, push the button on the left and enter the desired distance between 2 points recorded for the
“
fixed distance
” trace
. It is interesting to record this trace during GPS auto-correction waypoint recording. It
associates waypoints with distance on every wheel. Then it allows to add correction points in the GPS waypoints
file, after the end of scouting, once back in office.
File name is:
Scout_date_hour.csv
The format is the following:

GMT Hour
is the time-stamp from the GPS. In France, add one hour in winter and 2 hours in summer.
-
Left
and
Right
distances are the main sensor input distances (non driving wheel),
-
AuxLeft
and
AuxRight
distances are the auxiliary sensor input distances (often driving wheel).
Note
:
Aux
check box has to be checked in
“

.
In this firmware version, only
“Peugeot/Citroën ABS” OBDII configuration is compatible with function
,

latitude and longitude in degrees. Can be copy/pasted in GoogleMap (after removing «

12.2.2 Traces with fixed time (0.1 second)
An
NMEA trace
(historical GPS protocol) can be recorded checking the check box on the upper right corner. Raw
data from the GPS are directly recorded, so 20 lines every seconds! This trace is not concern by Trip1 distance and
can be used to simulate the GPS on desk or can be converted in GPX or KML file. It is not recommended to record
this trace during scouting if you stop often to hand write landmarks because the files become huge.
File name is:
GP_date_hour.csv
12.3 Correction waypoints during scouting
Please see annexe document for this function. GPS auto-correction option is needed.
