you can derive course, speed, and target position from bearings only, radar or sound bearings, it doesnt matter. below is a link to the maneuver board manual,
i beliieve its on page 56 of the manual , you will find a chapter headed, "COURSE, SPEED, AND POSITION DERIVED FROM BEARINGS ONLY".
that chapter will teach you how to obtain the target data you asked for from bearings only.
now, i did this once, using sh3 and sh4, i had it all worked out, and i was going to present that as a tutorial on the forums here, unfortuately, i had to do a few system recoveries, and lost all data.
i would do it again, but its really intensive, and im getting very lazy, and dont wanna do it again. the key to it all is bearing changes, and that more than anything else determines
COURSE, SPEED, AND POSITION
you need a parallel ruler, which sh4 does not have, but you can use the nav tools and make one, maybe later ill send up some pics of the sh map, showing how to use and make a parallel ruler.
if you try the chaper on "COURSE, SPEED, AND POSITION DERIVED FROM BEARINGS ONLY" from the manual, you will find that its time consuming, i dont know about you, but i know i have no time for something like that to work
out.
so something else was made that hunts and kills targets with ease, and whats great about it is you dont have to map plot. its called the point and shoot technique, and there is a thread somewhere here called
the "point and shoot" thread, locate that on subsim forums, learn it, and you see how easy it is to track and kill ships using sonar, radar, and or visual sensors.
it is also my belief that world war 2 submarine skippers, on both sides of the atlantic, used this method, i know captain eli t reich used this method to take out bb kongo in 1945.
not only is this technique lethal as hell, if you learn this technique well, you leave the PERISCOPE and TDC dependent on these forums behind. now you bring all your long range sensors to bear, you can attack and kill ships that you
have no visual sighing on. dont let others here tell you about the consequences of shooting at unidentified targets, you might here that argument, but just remember, that didnt stop captain reich, it should not stop you either.
another thing about the point and shoot technigue, silent hunter has seen four versions sh1 to sh4, and every time a new version comes out, the tdc is always different, and you have to relearn the tdc, with every new version that comes out.
with the point and shoot technique under your belt, you will be a killer, from day one of a new version, because the p+s method never changes, because its not TDC and periscope dependent, its all based on trig.
