* RFID technology (triangulation / averaging) is incapable of capturing accurate fractional times with any consistency, because of the random tracking errors inherent to this technology. These are impossible to overcome, especially when tracking fast moving objects such as race horses. These variable tracking errors vary from 3 feet to 30 meters or more depending on the accuracy of the computer model of the racetrack, calibration, and other factors such as the number of receivers installed around the racetrack, interference, size of the racetrack, number of horses, and other factors. In some cases the required number of receivers (wired) will be over thirty, without any gain in consistency.
RFID systems running on a wireless network will display even poorer results, due to additional delays, and crowding of the WiFi spectrum.
Autochart uses its proprietary patented timing and positioning technology to capture the ABSOLUTE position and timing data for each horse, while RFID tracking can only produce AVERAGED position which is not accurate or consistent to be accepted by Racing Commissions as Official Timing Data. In other words, Autochart's millisecond ac curacy will show the time difference of a finish by a nose.
RFID tracking providers MUST take the timing feed from a separate Infrared, LEADER TIME vendor at the working racetrack, or take the finish time from a photo finish system, and then interpolate their position information based on this third party provided timing data. The differences in accuracy and consistency between an RFID system and Autochart are dramatic.
