Farsounder 3D Colour Sonar for surface navigation and obstacle avoidance
The FS-3DT is one of FarSounder's main products for surface ship navigation and obstacle avoidance which uses Dual Transmission™ technology. Like the FS-3, it provides a 90° field-of-view depth map with a single ping. However, the FS-3DT also includes a narrow beam 1/4 mile range mode. This Dual Transmission™ design can be configured to automatically switch between the standard 90° ping and the long range narrow beam ping.
The system includes a 2U rackmount power module and a streamlined sonar head with Dual Transmission™ capabilities. The user interface is FarSounder's SonaSoft™ software which is a Windows XP software package that is capable of networking a single sonar head with up to 4 user interface stations.
The FS-3 DT operates at 60 kHz and has an accuracy of about a 1.6 degrees. The range of the system is shown below.
