Abstract
Method and system for synchronisation of measurements from a number of sensor systems functionally connected to a host computer, the method comprising - sending a trigger message M0 to the sensor systems for starting the measurements by the sensor systems and the transmission of the measurements to the host computer, - sending a sequence of following messages Mi (i=l, 2, 3, ..., N) from the host computer to the sensor systems and storing the sending time xi (i=l, 2, 3, ..., N) for each message Mi (i=l, 2, 3, ..., N) - for each received message Mi (i=l, 2, 3, ..., N) at a sensor system, sending response messages mi (i=l, 2, 3, ..., N) from the sensor system to the host computer, the response messages mi (i=l, 2, 3, ..., N) implying information indicative of the receiving times yi (i=l, 2, 3, ..., N) of the received messages by the sensor system, - storing the receiving time yi (i=l, 2, 3, ..., N) at the host computer for each received response message mi (i=l, 2, 3, ..., N) and relating the sending time sequence Xi (i=l, 2, 3, ..., N) to the receiving time sequences yi (i=l, 2, 3, ..., N) for each sensor system for finding a relative time shift between reception of the trigger message by the different sensor systems.
