From personal_submersibles at psubs.org Sun Sep 1 14:28:13 2019 From: personal_submersibles at psubs.org (Cliff Redus via Personal_Submersibles) Date: Sun, 1 Sep 2019 18:28:13 +0000 (UTC) Subject: [PSUBS-MAILIST] Underwater Navigation In-Reply-To: References: Message-ID: <279102197.965554.1567362493640@mail.yahoo.com> David, I wish that I had had the Navonics program loaded on my phone at the Flathead Expedition.? It would have been very helpful for documenting the dives and also to follow Sean Stevenson's direction who was SOC for the R300.? What happened several times is that he would position the tender over a dive site and give me a heading and a description of the topography.? On several occasions I ended up missing the feature they were directing me to.? If I would have had the application on my phone and used it like you did with Hanks dives, I think it would have made it easier to follow directions as we would be looking at the same topography map of the dive site. I have since downloaded the app and will use it for my next dive.

A few more thoughts have come to mind on my system, appreciate your thoughts. We could use 3 or 4 off the shelf transducers from a depth sounder system, hung 10 meters below buoys. Each having their own electronics enclosure, with GPS & electronics to transmit the GPS data acoustically to the submarine. The submarine transducer receives the signals which are analysed for their distance & GPS position then trilaterates it's GPS position based on these & it's depth. This GPS position is fed to the off the shelf boat chart plotter so we can visualise our position on a bathymetric chart, & chart our dives, logging way points of interest. We can also print out data on return. The subs GPS coordinate can be transmitted to all the buoys ( in case one is closer than the others) and this can be transmitted to the support boat. The cost would be 4 buoys, 5 transducers, batteries, maybe 5 arduinos or Similar, & a chart plotter. ( & hours of electronics & coding) I like the idea of transducers hung under the water as there is less chance of the signal being obstructed than with a seabed based system. It could be a plug & play system that could be shared among subs.

I am not a fan of towing ropes; too dangerous and probably more suited to shallow depths. Had a quick look at depth sounder ranges & it looks like they can do 3000 yds. So with 4 transducers & GPS receivers you could have a huge search area & an accurate plot of where you had been on a chart plotter. I have a friend that works at Navico here in Auckland where they do product development. He has given me the number of their top technical guy as I was interested in forward scan, & whether it could shoot through a fibreglass enclosure. This would be a great contact for this project if I wanted to pursue it further.

I have a video of my ambient submarines first surface trial in a swimming pool; in 5 seconds I had hooked up on a rope that was hanging in the pool. Also a couple of years ago 2 advanced divers died in a local lake by getting tangled in rope. Vance was caught in rope in a working sub at depth one time. Anyway I will think a bit more about this system as it seems on the surface to have merit. Drop 4 buoys in the water & have a 9 square kilometre area that you can pinpoint your position in & map your position on a chart. A line is drawn on the chart of your past course so you can easily grid search. Come back later & go to exactly where you want. Go home & analyse your dive. The cost is not excessive. 5 transducers at under $250- each. 4 inflatable buoys, 4 lead weights lines & winding reels. 4 electronics enclosures ( off the shelf from blue robotics), 4 GPS receivers ($20-)each. 4 X lithium batteries, Electronics (maybe 5 X $50-) Most depth sounders come with a chart plotter now, so people may already have one. And Jon can do all the programming :) Alan > On 2/09/2019, at 8:50 AM, hank pronk via Personal_Submersibles wrote: > > Alan the tow line to the buoy is safe because it is jettisoning normally.

The group did a lot of work on home made passive sonar with Piezoelectric transducers. These are very cheap. Perhaps make up a circular array of narrow beam passive sonars, with a central transducer pointing down & the outer ring of transducers angled out slightly. Have one wider angled transducer for transmitting data. Hang the array to a small floating platform that has two small electric motors on it for tractor steering ( think radio control boat size) & a GPS receiver. The submarine transmits from one or two transducers with a narrow beam. The surface unit will be able to follow above the sub based on which of its transducers is receiving the strongest signal. It will always attempt to have its central transducer receiving the strongest signal. It will periodically send it's GPS signal to the sub which passes this signal in to an off the shelf boat chart plotter. The sub can send its heading & speed information to the sonar array to help It keep on track. My idea may sound a bit fantastic but there are kids toys more complicated. I bought a NZ $200 drone with a video camera, return to take off & follow me functions. Also Minn kotta have a thruster that is radio controlled & has a GPS hold position function. Have a few more thoughts but will stop here.

At first, the system had lots of bugs and issues. I was on their back for a year. The position would jump all over the place due to backscatter signals, especially on the flat sandy seabed and still surface. With new software and firmware, I can now see the rov position directly on google earth map or esri maps. The position is stable and the system seems to be operating well. However, both these systems are intended to be the sub, rov or divers position on the surface. You will not be able to see your position from within the sub. BUT, it may be possible to use 2 of X150 as they are both transponders/transducers to be able to get the relative position from the X150 on the sub onto a laptop onboard the sub. If they have a software to do so is a different question....who knows. FAnother option - this type of equipment is better suited https://www.blueprintsubsea.com/pages/product.php?PN=BP01068 I have very little knowledge about it.

I think there was a single two-conductor wire from the batteries to the motor switches on the control handles. The cable disappears into the handle which goes through the hull to the motor. That's it. Mark added one cable to a light. That strikes me as fool-proof, extremely unlikely to fail, and very easy to work on.

The red looks good now, but if you are thinking that it is too bright then don't be too concerned because red tends to fade quickly so it may tone itself down in time. -----Original Message----- From: Personal_Submersibles [mailto:personal_submersibles-bounces at psubs.org] On Behalf Of hank pronk via Personal_Submersibles Sent: Wednesday, September 11, 2019 5:35 AM To: Personal Submersibles General Discussion Subject: [PSUBS-MAILIST] (no subject) Hi All.

They are a young bunch of guys from the West Coast whose products I have mentioned before. They have upgraded their M200 motor, which is an open motor designed for seawater. I have 2 of their motors & are buying more of their new version. On the old version you had to solder your wires on & waterproof them. It was Very difficult but now they are pre-soldered. I can think of a few uses for them.

Asking 30K. For the past seven years Chesapeake Submarine Service in Edgewater, Maryland has been utilizing this submarine for piloting classes and the time has come to let someone else live their dream. We have two other operational subs, a K-250 (original Kittredge built VAST boat) and a three man sub built by a commercial diving company several years ago The previous owners were a father/son team who would take it offshore in the Great Lakes, drop to 100+ feet, take a compass heading and stay down four or five hours looking for wrecks, covering miles in the process. We don't think that we are doing this sub justice diving in shallow water just to give classes - we will continue to use our other subs for this. You can get all the information you will need by watching the youtube video "How to dive a K-350 submarine" (uploaded by us three years ago), or by visiting our facebook page at "Chesapeake Submarine Service".

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. -----Original Message----- >From: Alan via Personal_Submersibles >Sent: Sep 24, 2019 12:42 AM >To: personal_submersibles at psubs.org >Subject: [PSUBS-MAILIST] Ping 360 Scanning Sonar > >Hi all, >thought this video on the Blue Robotics "Ping 360" scanning sonar was good, >https://m.youtube.com/watch?v=yXYo2c0TSJY >I am not sure whether it was on their site last time we discussed it. >It is rated to 300 meters. >Alan >_______________________________________________ >Personal_Submersibles mailing list >Personal_Submersibles at psubs.org >http://www.psubs.org/mailman/listinfo.cgi/personal_submersibles From personal_submersibles at psubs.org Fri Sep 27 01:50:56 2019 From: personal_submersibles at psubs.org (Alan via Personal_Submersibles) Date: Fri, 27 Sep 2019 17:50:56 +1200 Subject: [PSUBS-MAILIST] Ping 360 Scanning Sonar In-Reply-To: <1504694607.11815.1569557782171@wamui-bison.atl.sa.earthlink.net> References: <1504694607.11815.1569557782171@wamui-bison.atl.sa.earthlink.net> Message-ID: Hi Ian, that sounds like a lot of work.

Also a lot of components and complexity to keep dry and reliable, I feel that that might be half (or more) of the challenge. I would start with a smaller part first, like a compass using a fiber optic gyro and a 3D flux gate compass. Then get some experience dealing with the issues of reliability of more complex/sensitive electronics in a sub-interior environment. Once I think I've got some electronic-environmental solutions, I'll look at getting a simple sonar setup. And just keep building from there. For your powered buoy, will it be able to relay position data back to the sub? I had an idea for using a tethered buoy to do positioning. The buoy would be tethered with an ROV cable which was strong enough to be the sole tether and could do (relative) high speed digital comms between sub and buoy. The buoy would have a GPS receiver and an acoustic pinger on board. On board the sub, a direction finding passive sonar (3 or more transducers) and a digital depth gauge. To get the sub's position, send a command to the buoy to return a GPS reading and send a ping at the same time, simultaneously take the sub's depth reading. Once you have the depth of the sub (digital depth gauge), the direction of the buoy (direction finding sonar), and the distance from the sub to the buoy (time from the ping sent to ping received), it's a bit of trigonometry but you can determine the position of the sub relative to the buoy. This sub-buoy position delta would be used as an offset to the returned GPS coordinates, giving the actual position of the sub.

The tricky part would be the direction finding sonar. I had thought of a tethered buoy with a device underneath that determined the angle of the tether. Lots of variables though, like a bow in the tether if you turned back on your path. At a depth of 250ft your position could go out by quite a bit, & current could effect it. With the motorised buoy idea you would have 2 small RC boat motors giving tractor steering & an array of 4 or 5 sonars. There would be 1 sonar pointing down & the others pointing outward on a slight angle. The buoy would move toward the strongest signal, continually attempting to keep the buoy directly above the submarine. The buoy would have GPS, & send it's position periodically via an acoustic signal to the sub. The sub in turn would send speed & directional information to the buoy so that it could predict It's required speed & direction. I REALLY like my idea of hacking a standard boat chart plotter & feeding the GPS signal from the Buoy in to it. That way every thing is plotted, you can put way points in & easily go back to any points of interest. Possibly synchronise readings from an electronic depth gauge with the chart plotter. You will have fun going about it bit by bit the way you described. That's probably a wise approach. If you are diving in the sea the tidal currents will add another level of complexity. As a diver I have had a lot of trouble at times finding a cray hole I thought was easy to find again; so have no illusions as to how difficult it is navigating under water.

But that was for casting a dome. Also met their head technician at the underwater intervention convention. He was a very nice guy. I had a much cheaper quote for a pressed dome from a European manufacturer. Am away from home, but may find it on my computer somewhere. Greg had advised me to go with a pressed dome. I am not sure whether Emile is selling to the U.S.A. because of liability issues. But if you were interested in ordering a large thick gold fish bowl he might be helpful.
