Sea trial of the new Datawell GPS directional waverider

Results of the first independent sea trial of the new Datawell GPS systems are presented. Measurements were conducted using a standard Directional Waverider buoy fitted with the new GPS sensors and the traditional accelerometers. This enabled a rigorous comparison with the tried and tested Directional Waverider. The new GPS system performed excellently, giving essentially the same results as the accelerometer sensors. The relative advantages of each measurement system are assessed.
