Introduction to SeaScape With SoundTracks PDF (5 Mbytes)

SeaScape - our navigational flagship - is designed to be the workhorse when navigating surface ships and submersables with integrated acoustic LBL, USBL, Dopper Velocity Log and GPS systems. It does everything Workboat does and much more. (Recommended reading up on WorkBoat also.) In fact, SeaScape AND WorkBoat are often used together for coordinated operations between the chief navigator, vehicle console, vessel bridge, science logging stations, etc. We're very proud of the fact that this combination of software is used to unite teams of people at sea who are tasked with complex missions.

Since 2009, SeaScape has been used to deploy the two largest undersea observatories on Earth: Ocean Networks Canada and the USA's Ocean Observatories Initiative (NSF) off the coasts of British Columbia and Oregon . Before that, SeaScape was involved with numerous national and international expeditions since the early '90's when it was primarily an LBL navigation program. With its genesis in LBL, it's not surprising that SeaScape now offers passive LBL navigation as well!

If you're interested, see the details below. (A new SeaScape PDF brochure is coming soon!)

Passive Long Baseline Operations...NEW
SeaScape now supports PASSIVE long baseline navigation as well as the usual active ranging modes. For more details than the brochure linked above, read this introductory PDF:

USBL Operations
SeaScape supports IXSEA's 'GAPS,' self-calibrating USBL system with it's built-in PHINS attitude sensor. To date, GAPS has demonstrated superior performance and ease of use compared with other quality systems. The Simrad HPR series, Sonardyne's 7705 and ORE's Trackpoint series have also been used with great success with SeaScape.

Generally, USBL systems are enabled and controlled separately from SeaScape and provide their string data periodically. SeaScape automatically recognizes these independently of interactive LBL operations that might also be ongoing. In addition, SeaScape provides a "Custom Input" facility for supporting ad-hoc USBL systems that are not yet automatically supported (as in NMEA-0183 strings). These custom inputs support the three common ways of reporting USBL positions: Relative X, Y, Z; slant range, bearing and horizontal deflection; and, horizontal range, bearing and depth.

USBL fixes have their own definable icon symbol, color and 2-D shape and can be associated with vehicle attitude sensors, just like LBL and DVL fix objects. They produce snail trails and like all "navigable objects" in SeaScape are monitorable, filterable, relational, mouse-identifiable and available for output of all kinds.
Active Long Baseline Operations
A big subject! SeaScape provides the navigator with unprecedented control of LBL / USBL / DVL operations from deployment and calibration of up to 15 LBL bottom transponders to the navigation of up to 12 LBL relays all with simultaneous support of USBL and DVL (Doppler Velocity Log) with no confilcts. Hardware and software "range gates," advanced, real-time ray path bending support, track histories, custom shapes, vehicle sensor input, active LOP graphics, DXF CAD file displays, bathymetry contours....and more...are all standard features. Dual vessel operations are supported with multiple vehicles, dual arrays, etc.

DVL Operations
SeaScape supports Teledyne-RDI's Workhorse Navigator series of bottom Doppler logs in both their "PD0" and "PD6" output formats. SeaScape's support for PD0 includes the ability to generate a "current profile" from TRDI's "water track" mode during an ROV or manned-sub dive (excursion to the bottom). This feature, combined with the ability to generate a "Sound Velocity Profile" (SVP) from their DVL (if thermistor installed!) rounds out the use of their system for maximum advantage. Up-to-date SVP's are obtained once the vehicle reaches the bottom and the SVP is available for input to not only SeaScape itself, but also any USBL or LBL system that may be in use.

SeaScape supports homing and rehoming of the DVL's origin (start) position to ANY navigable object in the SeaScape system: LBL fixes, USBL fixes, the Crosshair, GPS, etc. Logging of DVL fixes include these homing decisions so that a faithful DVL track is generated. SeaScape allows the concurrent plotting of any past or current DVL track along with it's current "snail trail" generation. Just like LBL and USBL fix objects (transponders), DVL fixes are monitorable, filterable, relational, mouse-identifiable and available for output of all kinds. And similarly, they can have their own attitude sensors and share the same system-wide variables as other navigable objects.

Mooring Calibrations
"Boxing" (also known as "box-in"): support for five acoustic transceivers including the popular EdgeTech 8011A and 8011M, the Benthos DS7000, their UDB-9000 and -9400 series and their ATM880 and 9000-series ranging acoustic modems, and the LinkQuest acoustic modem. Range corrections using average speed of sound, sound velocity profile averaging, and ray path bending. Import / export SVP's. Control of fix generation including 2D / 3D, seeding, use of ranges, etc. Ability to load / view / resume past calibrations. Full access to files generated. Use SeaScape's / WorkBoat's "Calibrate Mooring" feature to calibrate an entire LBL array if you want - or use SeaScape's comprehensive statistical "steam the array" methodology - proven to be mathematically correct. You'll know where your instruments are. Also, use it for emergency location of any device with a compatible transponder, e.g. "sub sunk" operations.
