Technology

• A network of 31 RF transceivers are placed around
  the track
• Every 80ms, they send an RF signal that detects a
  small transponder (tag) placed in the jockey's
  cap
• The location processing server (LPS) then
  calculates the tag's location on the track
• From the LPS, sectional times are captured, and
  tracking data is sent to the graphics systems for
  multimedia display

Timing Methods Terminology

• Finishing time (official)
• Each horses race time
• Generated from the photo finish system
• Sectional times
• Overall sectional time (for lead horse)
• Individual sectional times
• Both generated by STRIDE
• Accumulated sectionals
• Total of horses individual sectional times
• Variance with official finishing time
• Timing facts
• 1 horse length is approximately 2.43 m
• 1 horse length travelled in 0.158 sec
• Difference between jockeys cap and horses nose
  is approximately 0.05 sec

14
Timing Methods Terminology

• Finishing time and accumulated sectional times
  will not be the same
• Taken from different systems
• Photo finish time measured by horses nose
• Accumulated sectional times measured by tag in
  jockeys silk cap
• System variance is /- 10 cm
• Average 0.02 sec per section
• Average 0.08 sec per race
