Navlya Hydroacoustic Navigation System of Underwater Positioning (HNSUP) is designed for coordinates setting of underwater objects (autonomous and towed submersible vehicles, various underwater research instruments and stations) relative to the base station (carrier) in the ultra-short baseline mode.
<p><b>HNSUP composition:</b></p> <ul class="check"> <li>shipborne hydroacoustic antenna (SHA) – 1;</li> <li>hydroacoustic transponder beacons (HTB) – up to 10;</li> <li>additional equipment providing given technical characteristics (GLONASS/GPS-receiver, roll/pitch/heading sensors, depth sensors).</li> </ul>
|Maximum slant range of object location relative to the HNSUP antennas||1500 m|
|Maximum depth of transponder beacons||700 m|
|Maximum number of surveillants||10|
|Range positioning accuracy||1.5%|
|Bearing positioning accuracy||0.8 deg.|
|Transponder beacon operation frequency||30—40 kHz|
|Operating temperature||–2 ÷ +50 °С|
|System setting-up time||2 min|
|Operating personnel||1 person|
|Transmission of location depth values on special request from the transponder beacon||0—700 m|
Afalina-GASP Hydroacoustic Positioning System is designed to determine the location, movement parameters and routes of objects on the real time basis.
Supervizor Sector Scan Sonar with enhanced resolving capacity is designed for display of acoustic images of underwater objects.
