| 摘要 |
This invention relates to a method for synchronizing a clock of a traffic monitoring system, by periodically transmitting a synchronization signal to the system from a satellite, which signal forms an indication of the exact time, comparing the time indicated by the clock with the signal, and adjusting the time indicated by the clock if this differs from the synchronization signal. The satellite can be a navigation satellite, whereby the location of the system can also be determined from the received synchronization signal. The time or the operation of the traffic monitoring system can for instance be adjusted on the basis of the location.
