| Definition | A Doppler velocity log (DVL) which provides platform attitude and altimetry data for navigation and positional control, with optional current profiling capability. The Pioneer DVL uses a 4-beam phased array transducer and has been designed with unmanned and remotely operated vehicles in mind to enable integration with small, portable underwater vehicles. Other applications include surface and sub-surface manned and unmanned vessels. The Pioneer DVL features an attitude and heading reference system (AHRS) microelectromechanical system (MEMS) based inertial measurement unit, which integrates three gyroscopes, three magnetometers, and three accelerometers running an extended Kalman filter, allowing the heading sensor to be semi-resistant to magnetic transients, providing accurate orientation data in both static and dynamic conditions. The instrument also features leak detection, and real-time leak detection monitoring, in addition to transducer health monitoring. A 300 kHz version is also available, in addition to an Acoustic Doppler Current Profiling (ADCP) option. Bottom tracking is between 0.5 and 100 metres. Water profiling is between 1.9 and 60 meters. Acoustic centre frequency is 614.4 kHz, with a nominal beam angle of 30 degrees, and bandwidth of 6.25 % of centre frequency. The instrument is depth rated to 1000 and optionally up to 4500 m, in temperatures between -5 to 45 degC. | |
