The SKIPPER GDS-101 is an advanced electronic echo sounder designed to continuously measure the depth of water beneath a vessel. It is an important navigation aid that helps officers monitor safe under-keel clearance while sailing in coastal waters, rivers, harbors, and restricted channels.
The system transmits high-frequency ultrasonic pulses through a hull-mounted transducer. When these sound waves reach the seabed, they are reflected back to the transducer. The processor accurately measures the travel time of the returned echo and instantly calculates the water depth, which is displayed on the bridge.
The GDS-101 is suitable for both new vessel installations and retrofit projects. Its robust marine design ensures dependable operation under vibration, temperature variations, humidity, and demanding sea conditions.
The SKIPPER GDS-101 Echo Sounder operates using the internationally proven ultrasonic pulse-echo principle.
The measurement sequence is straightforward and highly reliable:
This rapid measurement cycle is repeated continuously, providing real-time depth information throughout the voyage.
The SKIPPER GDS-101 Echo Sounder is engineered with precision electronic and acoustic components that work together to deliver continuous, accurate, and dependable seabed depth measurements. Each module plays a critical role in ensuring safe navigation under all operating conditions.
The display unit provides real-time digital depth information, echo presentation, alarm indications, operating modes, and system status. Its high-visibility screen allows bridge officers to monitor water depth quickly during both day and night navigation.
The transceiver is the control center of the echo sounder. It generates ultrasonic transmission pulses, receives echo signals, processes acoustic data, calculates depth, and communicates with the display unit.
Mounted below the ship's hull, the transducer converts electrical energy into ultrasonic sound waves and receives the reflected echoes returning from the seabed. Its performance directly influences the accuracy of depth measurements.
The signal processing circuit amplifies weak echo signals, filters background noise, and performs high-speed digital calculations to provide stable and reliable depth readings.
This module supplies regulated power to the entire system while protecting sensitive electronic circuits against voltage fluctuations commonly found in marine electrical networks.
The GDS-101 includes programmable shallow-water and deep-water alarms, enabling navigators to react immediately when preset depth limits are reached.
The system supports standard marine interfaces for integration with bridge navigation equipment, voyage data recorders (VDR), integrated bridge systems (IBS), and other compatible onboard monitoring systems.
Note: Actual specifications may differ depending on the installed configuration and transducer option.
