Typically the data is collected in 15-minute, 30-minute,or one hour intervals, but can be collected on any interval required.

The data is transmitted thru the GOES satellite to ouroffice on 1-hr or 4-hr intervals, depending on the baudrate of the transmitter.

The data may be transmitted on a random interval once certain threshold limits are reached.
