[PSUBS-MAILIST] Ping 360 Scanning Sonar

[irox via Personal_Submersibles]

Hi Alan,

one of your fwd's from Blue Robotics had links to it, it looks really neat.
Probably the most exciting part is the open source aspect, since we can
potentially customize the software to our needs.

One project I'm interested in advancing is combining FiberOptic Gyros, Mems
accelerometers, 3D flux gate compass, and sonar, as part of a underwater
navigation, mapping and positioning system.

Essentially, the IMS sensors are used to understand short term movements of
the sub (drift won't be a worry short term), which helps with accurately
determining the positioning of the sub relative to the sonar targets.
Then do characterization analysis on the sonar data to determine which
objects are static (not moving) and objects not persistent (moving or unreliable
to image with sonar).  This allows us to generate a persistent sonar
image/map (remembering all the things that were observed previously), and use
the previously identified static objects/characteristics to accurately determine the
sub's current position/location via sonar and IMS data.

I did build part of a proto-type for this a few years ago, but other things
came up.  I think this would be great thing to add to Gamma. :)

Cheers,
  Ian.
