[REL] Solution Solver 2.3

[Pisces]

Thanks, much more flexible with that free pointer like this.

I noticed some excentric movement as the middle (distance/speed) disk is moved around. It it correctly centered? Or is this a non-circular image?

You'd have to ask the person who made that artwork. It is literally the same graphics files from the wolves of steel mod.

The lead solver disc had the same issues years ago, because the artwork was reaper7's work. I had to completely remake them from scratch in Adobe Illustrator to get them to be perfectly circular and everything lined up with no wobble. That took alot of time.

Im not doing that again for the attack disc, because frankly i dont even need or use it with all the other tools available. I added it because someone requested it. All of the hash marks line up with each other as its rotated, a slight visible wobble wont hurt.

Ok, it doesn't lead to gross errors. I know it can be a big task. I remember working on the 3-bearing AOB finder in my dreams the days after.

Awesone ! I would have liked to be able, in "AOB finder" when I save by pressing the + , the dimensions of the boat ... Alas it is necessary to reenter those dimensions each time .... Great tool anyway

It does save them, thats the whole purpose of the feature.

Pushing the + sign adds a new contact to the list. It starts the contact off with the same dimensions that was currently displayed (ie. dimensions of the previously selected ship). Once you enter the new dimensions on any selected contact it remembers them for that contact.

Summary:
Push the + sign button to add a new contact, then enter its dimensions. It is now saved for that contact. Everytime you reselect that contact, the dimensions for that ship will be called up.

No it doesn't for me ... I run windows 7 64bits , application with admistrator rights and all security checked .... I don"t understand .. v2.3.2.0 How do you call the save boat ? Just clicking on it ? No still the last dimension entered ...

Gali! AFTER A TEN YEAR SILENT RUN!

Are you talking about ship measurements in meters, or degrees on the periscope?

Newcomer here: Hydrophone plotter - I understand the mapping of the initial three bearings into the course of the target. How do I get the Range on Bearing 4? Let's say I have it set for 10 min intervals. Do I

1. Plot board - plot my own position with the predicted bearing 4
2. Move out briskly and change position for say 8 minutes
3. Stop
4. Take a new bearing and plot that to cross the predicted bearing 4, giving my range?
5. Measure the distance to the crossing along bearing 4 (not the one I just took).

Is that the meaning of "Range on Bearing 4"?

[Pisces]

Yes, take 3 bearings from stationary position. Determine target course. Predict the 4th from stationary position. Move away from stationary position. (Often parallel course gets a nice crossing.) Take real 4th bearing from new vantage point and locate target at cross-bearing. All time intervals between bearings should be equal. So no 10,10,8. Then measure distance moved through bearings and triangulated position. Calculate speed based on interval.

(There are other 4 bearing methods that work in a different way and can be done moving all the time. See some PDFs in my lowest signature link. They have to be drawn manually on the map, Gutted's program doesn't work like that.)

@Pisces thank you for the info. I played with it in Tutorial mode last night and my results are mixed. I'm taking optical observations with the periscope for the bearings to make sure my bearing errors are minimal, yet out of 4 scenarios I got one perfect target course and speed, and three for which the course was way off. I need to figure out where the problem is (me being most likely, but taking those bearings is drop dead easy and I triple check them).

I saved the numbers and will plot them on the board today. I'll also look at your tools. I really need to be able to plot the convoy course and speed while under way. I hate the thought of guessing the AOB "by eye" and having the target course solves that problem the right way (I know they can zig so maybe I'm dreaming). It (under-way plotting) can be done on the plot table, but it's work-intensive and error prone, especially while playing solo. I'm not even ready to join a crew and get us sunk or cause misses ha ha.

I got the Four_bearings_method_revised_v2, Neuro.pdf. Thanks very very much. I have more to learn :-)

Gutted's hydrophone tracker can still be used under a constant moving condition in some way. The theory is that, the same formula used to extrapolate the 4th bearing when stationary can also be used when ownship is moving at a constant speed & course.

[Pisces]

It can be used to predict the 4th 'imaginary' bearing. But the plot it provides falls apart if you are moving. You would need to plot your predicted position along the old course for the 4th instant and draw it on the map yourself anyway. Then find the intersection with the bearing from your actual position.
