FarSounder's Technology Blog

From time to time, FarSounder's development team likes to toot their own horn and tell the world about some of the cool things they are working on. We can't share all our secrets and development plans, but we can share some of the excitement that our engineers experience every day working for FarSounder.

Overview of 3D-FLS survey in Portsmouth, NH
What is under the water in front of your ship right now? With the use of only charts, radar, and other traditional methods, this can be a difficult question to answer. This is where FarSounder’s forward looking navigation sonar comes in, and through both research and collaboration, FarSounder is able to conduct numerous survey projects in the Northeast.

FarSounder and URI Students
This past year, FarSounder partnered with the University of Rhode Island ELECOMP Capstone Program. The program allows students to work with local businesses on designing, building, programming, and testing solutions to real-world problems. It is not only educational for the students, but also helps to provide educated workers to Rhode Island state’s businesses. At FarSounder, students have benefited from hands-on experience with our high-tech sonar while working to apply theory from their studies to practice.

Vessel track in Antarctica
Recently, FarSounder launched an Expedition Sourced Data Collection program allowing customers to record data during their normal operations.We already have a fleet of customers collecting data as they use FarSounder's real-time 3D-FLS to increase safety in their day-to-day operations. Some of the exciting areas they are exploring include the arctic and antarctic waters, as well as the Caribbean.

The world’s oceans and the environments they encompass are vast and varied. The bathymetric contours and acoustic conditions found in the seas, oceans, and bays, around archipelagos and reefs, and through the latitudes mirror this complexity. FarSounder sonars are designed to bring clarity in these varying conditions to the operators aboard our customers’ ships. Over the years, we’ve amassed many terabytes of sonar data from vessels and locations around the world with varying times of year, installation types, vessel speeds, and signal types. This data is used to continually test new software releases and algorithms.

Example of 3D-FLS signal strength data
Convolutional neural network (CNN) models have grown in popularity in recent years by demonstrating impressive performance in many fields. These models have been applied to complex problems in many domains. Given the added performance and flexibility offered by these models, we had to ask: “Can we incorporate a CNN based model into our current processing algorithm?”

Transducer Module Internal Electronics
FarSounder sonars use a sophisticated data acquisition system to digitize underwater acoustic signals. These custom electronics are designed in-house and are one of the reasons 3D forward looking sonar is possible today. Recently, the electronics in our Transducer Module underwent a major refresh bringing some of the latest technology to our products; one of the ways FarSounder is always looking ahead.

Patience Island Survey Footprint
Over the past 14 years, the use of 3 dimensional forward looking sonar (3D FLS) for real-time navigation has been adopted globally by a growing number of vessel operators. FarSounder’s 3D FLS technology insonifies the area (the sonar’s field of view) ahead of the vessel (up to 1000m) and allows navigators to determine not only the range and bearing to navigational hazards within the field of view, but also their depth in the water column [1]. In addition to real-time information about navigational hazards, the depth of water ahead of the vessel is also obtained. Determining the depth of the seafloor ahead of the vessel as measured by a 3D FLS is useful for real-time navigation, but are there other applications for this data?

Currently, the main application of commercially available three-dimensional forward looking sonar (3D FLS) technology is for real-time vessel navigation. Using 3D FLS technology, the vessel operator can detect not only the range and bearing to a navigational hazard, but also the depth of the hazard in the water column.

Over the past 13 years, the use of 3-dimensionalforward-looking sonar (3D FLS) for real-time navigation has been adopted globally by a growing number of vessel operators. More recently, FarSounder started collecting bathymetric data using 3D FLS sonars in Forward Looking Multi-beam (FLMB) mode. Before exploring all of the possible applications of collecting bathymetric data on vessels with an installed 3D FLS navigation system, the accuracy and limitations of this data should first be understood. In this paper,...

I-Bridge® offered by TEAM Italia with FarSounder integration
Integration flexibility is one of the key aspects to FarSounder’s software. Since SonaSoft 3.0, all end user features can be controlled with only a 2 button mouse/trackball and the design of the user interface facilitates the use of touch screen monitors. We also offer low level integration via a network based SDK. New in SonaSoft 3.3, we’ve added support for customizable hotkeys. This new feature makes it easy to integrate physical controllers such as buttons, glass bridges, and custom foil panels, with our software. Any controller that can output a standard keyboard message can be used.
