Here's how I calculate at the moment: Using the ImageJ analyzing software and a selfmade macro-script.
*calculates direction to target based on mortar position and target
*calculates barrel elevation based on distance (mil and deg) and height-to-target
*easy corrections by manipulating top or base of arrow
*incl. minimaps of all maps
biggest benefit here is that you can communicate all settings to the mortarteam without them having to calculate anything or setting markers. = speed increase.
I uploaded the version i use so if someone wants to give it a try:
Download:
Mirror 1
Mirror 2
!requires java runtime environment!
v1.2:
*added relative height to target to the calculator.
followed by a quick guide on what to do:
open a map
select image ("program folder / minimaps")
select the macro!
notice the log-window.
drag arrows on map and see what happens.
so yeah, its all put together pretty sloppy for now but it works - faster than a spreadsheet i'd guess (no typing) so i'm happy. Still some stuff to do thought (like displaying grids and keypads so you know where u are while zoomed in etc.)
pls tell me what you think.
edit*
notes on what to add in the future:
*fix for maps with higher res than 1024x1024 (reset first digit of mapname to 1km or 2km for now)
*performance optimisations (calculations are done when left mousebtn is pressed, not the best way i imagine..)
*grid/kp-system features
*multible arrows if possible? (just open 2nd window for now)
*target-manager = caching of predefined or saved target pos. and access to fast switching
* ...

formulas used in the script:
Distance to Target
Barrel Elevation with v=121.306 and g=9.81 and x = distance, y = height
direction to target := atan2(vectorX,vectorY) * (180/PI)

some notes about using the mortars:
The fastest way for me to use the mortars is still using a list with chosen distances and the correct elevation for that distance. (not very precise tough)
So when you sit inside the mortar you usually wait there with the calculator selected and the squad-map open, so you get the distance as soon as the marker is changed. after that you get the correct elevation from the list, close the map and start shifting the mortar horizontally and vertically. (experienced mortards will do everything at the same time after getting the distance)
Also remember that firing more than 2 rounds each on the same position is mostly waste of ammo as most targets are in cover by then. Better send more rounds after a short break.
