Abstract
A method for compressing measurement data that includes grouping common data elements in common data messages. Sequential data elements in the groups are subtracted from each other to provide difference values. The difference values are compressed using a suitable compression algorithm to provide compressed blocks of data. Time stamp periods associated with each common data message are also subtracted from each other to provide time stamp difference values. The time stamp difference values are also compressed to provide compressed time stamp blocks. The compressed blocks of data and time stamp blocks are then stored.
