Abstract
Streams of data packets and timing pulses are received from a source. Time stamping of the data packets is carried out largely independent of individual timing pulses. A normalised pulse time of arrival is calculated, preferably as a running average over the most recent arrivals. Times of applicability for the content of the packets can then be calculated according to a predetermined relationship between the order of arrival and of corresponding pulses and packets. Data acquisition may take place from an external or internal data source. An example external source is a GPS receiver.
