A DriftBox is a device used in
the sport of drifting to teach event judges the qualities desired in it.
A driftbox is based on a

unit which can measure the drift angle of a car, while also measuring the speed,
''g''-force and circuit position. The DriftBox works by using the
Course Over Ground (COG) measurement from the GPS at ten times per second (which is in degrees from due North) and comparing this with the angle the car is pointing. The car's angle is calculated using a high accuracy
yaw rate sensor
A yaw-rate sensor is a gyroscopic device that measures a vehicle's yaw rate, its angular velocity around its vertical axis. The angle between the vehicle's heading and velocity is called its slip angle, which is related to the yaw rate.

, which is integrated over time to give angle.
In competition use, a score out of ten is awarded to the competitor by measuring the peak lateral g-force and the peak angle during a maneuver. All of this information is saved to a data logger (in the form of an SD/MMC card). The DriftBox can also be used to measure braking distances, quarter mile times and speeds, as well as lap times using a virtual start/finish line generated from the

In geography, latitude is a coordinate that specifies the north– south position of a point on the surface of the Earth or another celestial body. Latitude is given as an angle that ranges from –90° at the south pole to 90° at the north pol ...
