Abstract :
A 2.5-meter diameter, heave pitch and roll buoy, has been developed by CNEXO and NEREIDES Company. The ARGOS satellite system is used for data transmission. To be compatible with the ARGOS message length, raw data had to be processed on-board. This led us to use a digital band pass recursive filter technique, to obtain estimates of energy and mean direction in 19 selected period bands. Measurements at sea ( 
up to 9 meters) are presented herein. With its one year autonomy and ARGOS transmission and positioning capabilities, this buoy should prove useful to oceanographers world-wide.
