GPS Lap trigger
The GPS lap trigger uses a GPS signal to trigger the lap timer. To function this
timer an external GPS sensor (see
GPS Sensor [
}
143]
) has to be connected to
the device and a detection point with a detection range has to be defined in
RaceCon.
The GPS detection point is defined by the latitude and longitude. The easiest way
to get the latitude and longitude of a finishing line is due to a web mapping pro‐
gram such as google maps. With google maps, simply left‐klick on the spot
where you want to set the detection point. The information about the latitude
and longitude will show up, in general the latitude is given at first. You should
insert at least five decimal places for sufficient precision.

The detection range defines the radius of a circle around the detection point in
which the lap trigger can be set. The lap trigger will be set as soon as the dis‐
tance between the car and the detection point has reached its smallest peak. By
this function an imaginary finishing line is calculated inside of the detection cir‐
cle.
