Imported USBL Ultra Short Baseline Underwater Positioning System

EvoLogics GmbH, Germany——S2C R USBL Ultra Short Baseline Underwater Positioning System

EvoLogics S2C R USBL ultra short baseline underwater positioning system from Germany can provide accurate USBL positioning tracking and full duplex digital communication functions, with comprehensive and ideal performance, which can improveProvide excellent supplyA solution that is suitable for various application scenarios and has low space, energy, and cost requirements.

The S2C R USBL ultra short baseline underwater positioning system does not require positioning and communication mode conversion: positioning data is calculated simultaneously with acoustic transmission. These two functions complement each other in the integrated positioning and communication system, opening up new and extensive prospects for underwater applications.

The main features of S2CR USBL underwater positioning system are:

• S2C technology: S2C (Sweet Spread Carrier) scanning spread spectrum carrier technology: spread spectrum technology based on bionics research

• Data positioning: USBL can simultaneously perform positioning and data transmission, track 255 targets simultaneously, and be used as reverse USBL (iUSBL)

• High reliability: In harsh underwater environments, adaptive algorithms can ensure reliable performance, with built-in forward error correction and data compression

• Advanced Communication Protocol: A communication protocol with multiple advanced data transmission algorithms that can use high bit rates to send and receive large amounts of data under the same conditions; Sending and receiving short instant messages without interrupting the main data transmission between devices

• Addressing and networking: Components with broadcast functionality for relay links and underwater communication networks

• Low power consumption: and can be equipped with additional power-saving options

Application of S2CR USBL underwater positioning system:

Positioning offshore equipment: Track the location of offshore equipment during installation to ensure it is accurately deployed to the expected position.

ROV and AUV navigation: simultaneously track the positions of multiple ROVs and AUVs, and control their tasks using instant messaging commands.

Mapping: When combined with GPS or differential GPS, locate underwater features with geographic reference coordinates.

Increase measurement accuracy: Track deployed sensors and detectors to improve measurement accuracy.

Diver tracking: Simultaneously monitoring the positions of several divers performing tasks and communicating information with them.

The S2CR USBL underwater positioning system can integrate the following sensors:

ADCP Acoustic Doppler Current Profiler, SVP Sound Velocity Profiler, CTD Conductivity, Temperature, Depth, Pressure sensors, INS Inertial Navigation System, and more options can be added according to user requirements

Technical parameters of S2CR USBL underwater positioning system:

1. The slant range is estimated by measuring the time delay, and the accuracy of the slant range depends on the sound velocity profile, acoustic refraction, and signal-to-noise ratio.

2. Standard interface configuration combination: see optional items. The RS-485 interface does not support duplex communication and must be customized.

3. Only after installing the wake-up module can users configure the listening mode. The power consumption in listening mode depends on the settings of the listening mode.

4. For data with RS-232 interface, if Ethernet interface is used, the power consumption will increase by 600mW.

5. Contact us for more power options and configuration modes.

6．S2C R 48/78、 18/34 is the size of the formaldehyde plastic shell, while other versions are slightly larger; S2C R 12/24、 7/17 is the size of the titanium alloy shell, while other versions are slightly smaller.

7. An RS-232 connector can be replaced with an RS-485 or RS-422 interface.

When the wake-up module detects an incoming sound signal or data from the host interface, it will activate other parts of the device. The device will automatically shut down after completing data reception or transmission.

Note: The wake-up module is only compatible with RS-232 interfaces and not compatible with Ethernet, RS-485, and RS422 interfaces.

9. Internal Xsens ® MTi AHRS (Attitude Reference System) is used to compensate for equipment attitude changes. After installing AHRS, the power consumption will increase by 400mW.
