The Racelogic Coastdown software can be run using GPS only data in open conditions where the GPS antenna has a good, unobstructed view of the sky, but for the best results even in good conditions it is advised to connect an IMU.

The use of an IMU removes noise from the velocity trace which results in the required statistical accuracy being achieved more quickly, thus reducing the test time.

The smoothing achieved with the use of an IMU also makes the test capable of being performed in conditions which are less than ideal, such as in areas of heavy tree / building coverage, or for test tracks where the sky may be obscured by bridges.
