The Aanderaa DCPS 5400 series features innovative acoustic profiling ability to collect high quality current information at a depth of 300m, 4500m and 6000m (see model inforrmation below). The DCPS can also collect current information on moving and tilting platforms.
Exceptional compensation in moving applications
- Each ping is compensated for the corresponding tilt and heading, taking into account mooring or buoy motions
- The Doppler Current Profiler Sensor calculates the correct vertical distance to a specific cell for each beam.
Increased deployment time
- Low power consumption
- Reduced power consumption with broadband technology
Smart data quality control
- Increased quality control
- Automatic flagging of bad data; status report for each cell
- User selectable advanced autobeam algorithm; automatic selection of the best 3-beam combination to remove faulty cells in case of an object passing in front of one beam
Sensor communication protocols
The Aanderaa Real-time collector PC software can be used together with all DCPS versions. It simplifies the sensor configuration process and saves sensor data to files on a PC. The AADI Real-Time communication protocol is a XML-based protocol which also includes numerous metadata for all the data parameters from the sensor.
The Smart Sensor Terminal protocol is a simpler protocol which gives smaller message sizes since it includes a limited amount of metadata in the output. The size of the output message can be reduced in both protocols by only enabling the necessary data parameters. Both protocols use ASCII output which makes it directly readable without any conversion (no binary data).
DCPS model information
- DCPS 5400/5400R - Available as 300m depth rated
- DCPS 5402/5402R - Available as 4500m depth rated
- DCPS 5403/5403R - Available as 6000m depth rated
The DCPS 5400/5402/5403 can be connected to a Aanderaa SeaGuardII DCP or Aanderaa SmartGuard Datalogger using the CANbus based AiCaP protocol. It can also be connected to a PC or third party systems through the RS-232 interface using the AADI Real Time Collector or SmartSensor Terminal protocol. This makes the DCPS the ideal cost effective solution for obtaining current profiles in systems already containing a Datalogger.
The 5400R/5402R/5403R has the RS-422 interface for use on longer cables.
1 The Seaguard platform and the smart sensor are interfaced by means of a reliable CANbus interface (AiCaP), using XML for plug and play capabilities.

4 ZPulse technology which improves the statistical precision. Complex acoustic pulses comprising several distinct frequencies are combined into a single acoustic pulse. The ZPulse based DCS separates the received signal into different frequency bands, one for each frequency in the transmitted signal. Further it analyses the frequency shift using a high speed Digital Signal Processor using an ARMA based parametric model processing algorithm to find the Doppler shift frequencies. This multi-frequency technique reduces the required number of pings needed in order to achieve an acceptable statistical error. The achieved measurement precision is proportional to the inverse of the square root of the number of ping measurements in a measurement interval. The ZPulse DCS uses two frequencies and this gives a reduction by a factor square root of two compared to a single frequency sensor. A single frequency sensor needs twice the number of ping to achieve the same precision as the Zpulse DCS.
