Measuring waves with GPS. The DWR-G wave buoy measures waves with help of the Global Positioning System (GPS) only. It features a patented algorithm and custom-made GPS receiver. With a single stand-alone GPS receiver it can measure directional waves, up to 100 s periods, without any calibration ever, and even in the middle of the ...
Manufactured by:Datawell BV based inHaarlem, NETHERLANDS
Datawell’s smallest directional wave measuring buoy. With a 0.4 m diameter mini-buoy version Datawell completes its range of GPS buoys: DWR-G9, DWR-G7 and DWR-G4, with 0.9 m, 0.7 m and 0.4 m diameters, respectively. Just like its larger equivalents the DWR-G4 relies on the Datawell principle of measuring waves with a single Global Positioning System receiver (GPS). By now this technique is ...

The Datawell rubber cords originally designed to make a flexible mooring for the Datawell Waverider and Directional Waverider buoys have found many maritime applications. Nowadays rubber cord mooring ranges from small spar buoys via large navigation buoys to pontoons. Keeping pace with the extension of application the variety of diameter and elasticity of the rubber has been expanded over the ...

The Datawell Wave unit is an OEM version of the well-known Directional Waverider Mklll for measuring wave-motions in three directions. The unit gives out the real time heave, north and west displacements as well as common wave parameters like Hs and Tz and spectral data.The Wave unit is built around Datawell's accurate and well-proven stabilized platform sensor, enabling wave height measurements ...

The MOSE-G1000 measures its three-dimensional motion in 3 frequency regimes where each regime has its own precision. Centimetre precision is achieved in the high frequency regime (1-100 s periods). Here the MOSE-G1000 works just like the Datawell DWR-G directional wave buoys. For very low frequencies the GPS position is output every 10 seconds with a precision of several meters. In addition to ...

The Directional Waverider DWR-MkIII: Three years of continuous operation. The Directional Waverider hardly needs any introduction: it is the world’s standard for measuring wave height and wave direction. Its success is due to the proprietary well-proven and accurate Datawell stabilized platform sensor, enabling wave height measurements by a single accelerometer. For the wave direction, ...

The second generation Waverider SG (WR-SG) is a real-time non-directional wave height measuring buoy. Wave height is measured with a resolution of 1 cm using the well-proven Datawell stabilized platform sensor. The stabilized platform ensures that the buoy accurately tracks the vertical component of the orbital wave motion. In the WR-SG, the platform mounting of the sensor has been reinforced, ...

An accurate and reliable air temperature measurement at sea is quite a challenge. On the one hand, compared to a land-based sensor, spray and reflection of the solar radiation on the water surface pose extra requirements on the shielding of the temperature sensor, while on the other hand the marine environment is notoriously hard for mechanical ...

The Directional Waverider that integrates wave and current measurements. The wave sensor of the Directional Waverider equipped with the Acoustic Current Meter option (DWR4/ACM for short) is identical to the sensor in the well-known Directional Waverider MkI, II and III. Processing of the measured data is now performed at the doubled sample frequency of 2.56 Hz. The high frequency limit of the ...
