Για ποιο ακριβώς μοντέλο λες georgehh; Δώσε μας κωδικό. Στη φόρμουλα 1 τα χρονόμετρα χειρός χρησιμοποιούνται τόσο όσο και τα καταδυτικά ρολόγια στις καταδύσεις, δηλαδή ελάχιστα και μόνο ως επικουρικά των ειδικών συστημάτων χρονομέτρησης. Με ένα γρήγορο ψάξιμο βρήκα αυτές τις πληροφορίες:
The timing is vital to the smooth running of a meeting, everyone counts of the Olivetti/Longines men from the drivers, to the organisers, the television people and the press.
They cannot afford to make mistakes. And since the team was adopted by FISA and FOCA in 1982, they haven't made any. There have been momentray glitches, which drop the readouts from real time (ie as it happens) to a slight time-delay, but checking is quickly done and the computers are able to catch up.
This produces what the team calls the 'film' of the race, a collection of shees of paper from which you could write an accurate report of the race without having been near the track!
And it is all done to 10,000th of a second accuracy.
There are three separate high-technology timing systems. Each F1 car carries onboard a small transmitter which gives a different identification signal as the cars cross the line. Beneath the tarmac is a signal reception line which, through a decoder, registers the car, its speed over the line and its lap time. This is fed to the control tower where it is cross checked with two other computers, one triggered by a photo-electric beam across the track at the finish line. There is also a video camera which records the cars passing at 100 frames per second, with timing data superimposed on the film.
All this information is cross-checked by the computers and then sent on, instantaneously, to the many timing monitors that can be found dotted around the track.
There are four different transmission channels from the control box. These supply times to the race administration, the pits (where drivers can read them), the race commentary box, the radio and television commentary boxes, the press rooms and any other monitors capable of picking up the signal.
Η πηγή είναι αυτό το άρθρο από το 1989, έκτοτε απ' όσο ξέρω το σύστημα έχει βελτιωθεί ακόμα περισσότερο:
