Help - Finding a targets speed?

WolfyBrandon · 08-03-2005, 10:49 PM

Hate to ask a total newb question, but I guess everyone has to start somewhere,

How do you find a targets speed in SH3? I can find the range, bow angle and what not but I can't get a speed result for some reason. How exactually do you mesure it in the scope? I start the timer and run it for a while and i either get - or 0 kts as a result...

Thanks

Exactly 15 seconds on the stopwatch, usually gives you a good read...but not always.

You have to set the distance and AOB before you can set the speed..not sure if you have to have the proper ship type too.

Thanks for the reply guys,

Yeah I might not of had the AOB or range set right is why I wasnt getting a speed result. I was playing a little last night and after setting up all the other information I was able to get a few speed results.

Thanks again guys

I havent had any luck using the datapad find speed thing (unreliable results), so I quit using it and I wish you could enter the speed manually in the notepad like the other settings. The easiest method is to ask your weapons officer for a target solution early on and he is usually dead on with the speed, then you can update the range and AOB from there on if you want.

I use the map. Place a mark on the targets current position, then start the stopwatch in the periscope or UZO. Then you can place another mark on the targets position 1 or 2 minutes later and measure the distance with the map ruler. The tools in the map give you distances in kilometers, so .4 = 400 meters. To get the targets speed for any given time interval use the equation:

(D/t)*1.944

D is distance in meters, t is time in seconds, and * 1.944 converts meters per second to knots. I made an exel spread sheet that does this for 1 & 2 minutes and printed it out. Here are the results:

Distance in 2 minutes(meters); Speed (knots)
100 ; 1.62
200 ; 3.24
300 ; 4.86
400 ; 6.48
500 ; 8.1
600 ; 9.72
700 ; 11.34
800 ; 12.96
900 ; 14.58
1000 ; 16.2
1100 ; 17.82
1200 ; 19.44
1300 ; 21.06
1400 ; 22.68
1500 ; 24.3
1600 ; 25.92
1700 ; 27.54
1800 ; 29.16
1900 ; 30.78
2000 ; 32.4

I have verified this in game using the stopwatch and these results are always within 1 knot of the weapon officers speed. Using this method and formula you can make charts to figure the speed of any given time interval you choose.
