PRODUCT DESCRIPTION :

The NINGLU TECHNOLOGY CO., LTD Doppler Speed Log is an advanced marine navigation instrument designed to measure the speed of a vessel through water using the Doppler shift principle. This type of speed log is commonly used on commercial and military vessels to provide accurate speed and heading data, which is crucial for navigation and operational efficiency.

It emits high-frequency sound waves and measures the frequency shift of the returned signal, which corresponds to the speed at which the vessel is moving through the water. The unit provides both speed through water (SOG – Speed Over Ground) and speed through the water column. This is a critical metric for vessels operating in various sea conditions, including currents and tides.
