SKIPPER DL21 Dual Axis Doppler Sensor
SKIPPER DL21 sensor is designed for the SKIPPER DL21 Dual Axis Doppler Speed Log System. It provides Speed Through Water (STW) and Speed Over Ground (SOG) in two or three axes (Doppler). In addition, it provides Speed Through Water (STW) in one axis.
The SKIPPER DL21 is a Dual Axis Doppler Speed Log and a Single Axis Doppler Speed Log in one sensor unit. It is working on the Doppler principle, providing longitudinal and transversal ship’s speed (STW and SOG) and distance relative to seawater. The SKIPPER DL21 gives accurate navigation parameters, measured as they happen, and presented in a logical, user-friendly way.
The new DL21 Speed Log is designed for ships over 50.000 GT with a simultaneous and independent measurement of speed through water and speed over ground. This is according to the new IMO resolution MSC334(90).
