NASNet® Stations

NASNet® Station are designed to be deployed on the seabed in networks to provide accurate long term positioning throughout the water column, form seabeded to surface. NASNet® Stations provide extremely long range acoustic coverage, making accurate full field positioning coverage operationally and economically viable.

NASNet® Mini Stations:

NASNet® Mini Stations are designed to be deployed on the seabeded in networks to provide accurate positioning throughout the water column, from seabed to surface. NASNet® MS can be deployed either in frames or in buoyancy collars with a weight securing them to the seabed.

NASNet® MTrx:

NASNet® Mobile Transceivers (MTrx) are used to provide accurate positioning for remote objects. NASNet® MTrx can also be used as an acousitc data telemery link for internal or external interfaced sensors.


NASNet® ICIS
NASNet® ICIS (Integrated Control and Interface Software) is the user interface providing control of all aspects of NASNet.

ICIS is a modular system providing varying degrees of control and security for different levels of user.

The 3 modes provided by ICIS are:
-NASNet® Dynamic Positioning user;
-NASNet® Survey user;
-NASNet® Advanced user.

NASNet® BF(Beamforming Hydrophone)
A rigidly mounted NASNet® BF is normally used for calibration of NASNet® Station or positioning of the vessel. The BF is also capable of controlling and monitoring all subsea NASNet® components.

One of the distinguishing factors in the acoustic performance of NASNet® is the Beamforming hydrophone which provides greatly enhanced acoustic detection in challenging acoustic conditions.

The BF is designed to allow deployment through a standard 10" gate valve and is compatible with a range of Hydrophone Deployment Systems.

The NASNet® Dunking Deployment System (DDS) is also available for easy mobilisation where vessel positioning is not required.
