                  interval specified on the previous
                  card.

NOTE [1] The times on the ACCBIA cards should be input in advanced time order
         for each satellite. If the time order is not observed, GEODYN IIS
         will terminate abnormally.

IF CARD OMITTED: If the ACCBIA card is omitted, no biases will be applied to the
                 accelerometer data. If the ACCBIA card is present, but the 
                 second BLANK card is missing the program will terminate
                 abnormally.
