Telemetry in Frmula 1 2009, why? 2 analyze chassis data, e.g. handling, aerbalance, tire temperature derive necessary setup changes t imprve car behavir, e.g. wing psitin, brake distributin analyze engine data in terms f perfrmance and life time derive engine/ setup changes, dne by the driver, e.g. lambda, ignitin get bjective data fr race strategy decisins, e.g. pit stps, fuel quantity crrelate the driver feedback with bjective car data, prve driver requests Technlgy is restricted by rules: Only ne way cmmunicatin since 2003
Perfrmance f Frmula 1 Telemetry Systems 3 Vice and real time telemetry within ne unit Up t 400 independent data channels 3-4.5 GHz transfer frequency Transfer rate up t 1 Mbit/s 2 ms maximal time delay t pit and t head ffice On bard data strage fr lw signal quality regins 600 grams
