APOS Survey has been developed to provide a cost effective solution for subsea survey and construction operations, making it possible for the surveyor to utilise a vessel’s HiPAP system. Acoustic interrogations are interleaved or run simultaneously with the DP system updates, without making changes to the vessel’s APOS software or installation parameters.
The Kongsberg cNODE MiniS P series are SSBL and LBL transponders, with built-in high accuracy strain gauge pressure sensors.
These units are designed for positioning of ROV’s, drones/AUV’s, towed bodies and structures where additional depth data or depth aiding is required.
The cNODE MiniS P pressure sensor data can be reported on the back of the SSBL navigation reply pulse, without the need for additional telemetry.
A range of models with different pressure sensors are available to maximise the accuracy of the reading. The 100 m full scale rated unit is ideal for windfarm installation support work, whereas the 1000 m and 4000 m models are suited for deeper water research, construction, towfish and AUV operations.
The Transponder includes all the features of the standard MiniS models, can be configured by RS232 line or by acoustic telemetry and is fully compatible with HiPAP®, μPAP® and cPAP® medium-frequency underwater positioning systems for precise ranging and positioning utilizing Cymbal acoustic wideband protocol and FSK signaling.
cNODE MiniS has a compact housing for the transponder electronics which can be powered both by the internal rechargeable battery or external power 24 VDC supply. The power level for the transducers can be stepped in 4 levels depending on range and conditions.
Kongsberg Discovery’s innovation in domed-sonar technology combines a wide-bandwidth composite transducer with a patented acoustic lens to provide unprecedented image clarity from a domed sonar head. The result is Clariscan – a high-performance, multi-frequency imaging sonar.
Kongsberg Discovery’s M3 Sonar HF is a multibeam system with both imaging and profiling capabilites. The M3 Sonar HF provides high-resolution and easy-to-interpret images by combining the rapid refresh rate of a conventional multibeam sonar with image quality comparable to a single-beam sonar.
