The imaginary finishing line can only be calculated if all channel sources are defined cor-
rectly. The latitude and longitude channel sources are mandatory for the functionality.
Missing direction or speed source lowers the precision of the system.
Define the latitude and
longitude of the GPS
detection point.
Define the detection
range around the
detection point.
Define the channel
sources for Longitude,
Latitude, Direction and
Speed.
Note
The configuration of the sensor update rate and the detection range must insure to re-
ceive a valid GPS point in the detection range, despite the occurring vehicle speed near
the detection point.
– Race track topology and transmitter location frequently cause false triggers.
– Software functionality prevents acceptance of false triggers.
– Minimum vehicle speed for acceptance of trigger prevents false triggers while vehicle
is stationary in the pits.
– Time based re-trigger protection prevents false triggers due to signal reflections on
Home Straight.
– Lap distance based retrigger protection prevents false triggers due to track topology.
