PRECISE POSITION INFORMATION WITH HYDRO ACOUSTICS

Simrad a.s. introduced its Hydro acoustic position reference (HPR) system at the Offshore Asis Exhibition. Simrad HPR is a highly accurate navigation system for offshore applications that require precise position information relative to the ocean floor. The system is intended for drilling, reentry operations, surveying, underwater navigation and pipelaying. The super-short base line system uses the principle of phase measurement of hydro acoustic signals. A split-beam transducer performs measurement of the received signal, which a computer converts to the geometric angle of the transponder, measuring the depth of the transponder simultaneously. A multiple transponder option adds to system flexibility. Three of the systems are on order for both manual and dynamic positioning systems.
