GyroUSBL acoustic positioning system of British Sonardyne company is the perfect combination of,Acoustic technology and high precision attitude / heading sensor In recent 40 years, The whole system uses the world's most trusted WB2 broadband pulse digital technology and ultra high precision laser gyro technology, The system performance is greatly improved，Also known as accurate positioning technology leader In the offshore oil industry.

Loderstar GyroUSBL acoustic positioning system of British Sonrdyne company is integrated with Sonardyne's sixth generation (6G ®) HPT USBL transmitter and receiver with high performance and a Polaris attitude and heading reference system (AHRS) / inertialnavigation system (INS).

Sonardyne through the acoustic transducer of AHRS/INS and USBL for precise mechanical alignment. Loderstar GyroUSBL can be fast installation without the need for thecalibration of the system to determine the installation deviation anglebetween the ship attitude sensor and acoustic transducer. This can greatly reduce the time and cost of ships.

GyroUSBL HPT transmitter and receiver using Sonardyne company's WindBand 2 signal processing techniques,With Sonradyne's sixth generation products compatible. And can be compatible with the product analog signal and WB1.
