DS90 Doppler Speed Log
DS90 Doppler Speed Log Introduction
1. Confirm to IMO MSC.334 (90). Has CCS certificate.
2. Pair-beam system effectively reduces error caused by pitching. The transducer assembly symmetrically emits tow sonic beams, one fore and the other aft. By averaging the Doppler shift in both directions accurate speed data is available under rough sea conditions.
3. Speed and distance information on the bright 7-inch TFT display.
4. Speed output to RADAR, ECDIS, AIS, VDR, GMDSS equipment, etc.
5. Fully meets SOLAS carriage requirement for ships over 300GT.
