We use 185 and 97 because the telepad is located at 185,97.

#Write down that distance somewhere
 
==Step 2==
'''Now this next part requires some math and a calculator supporting square roots and inverse trigonometric functions, specifically asin() and atan().''' If you're incapable of math, ask yourself what the hell are you doing in the Research Division of the most high-tech space station ever built, and apply to [[Head of Personnel]] for the [[Clown]]'s job.
 
First, let's find the power offset. It is most simply done by setting elevation to 45. Elevation set to 45 sets the sin(2*elevation) to 1 so the equation for the distance simplifies to (power^2)/10. For example if you teleport something with power 20, it should be (20^2)/10 = 40 tiles away. That's where the power offset comes in, as the GPS will actually be in ((power-offset)^2)/10, so, using the previous example and if the offset is, say, -4, the GPS will be actually ((20-4)^2)/10  = (16^2)/10 = 25.6 (rounded to 26) tiles away. So, to find out the power offset, you need to teleport the GPS with 45 elevation and see how far away it actually flies. Let's designate the GPS coordinates as X and Y, and the telepad coordinates as Xt and Yt. Then the formula for the distance from the telepad to the GPS is:
*distance = sqrt((Xt - X)^2 + (Yt - Y)^2)
and the equation for actually finding the offset is:
*((power-offset)^2)/10 = distance,  therefore (power-offset)^2 = distance*10,  therefore '''power-offset = sqrt(distance*10)'''.


So, to recollect, to find the power offset you need to:
Write down that distance somewhere.
*Teleport the GPS with settings 0 bearing, 45 elevation, 20 power.
*Using another GPS find out how far did it go in both x and y directions (say, it travelled X tiles on x axis and Y on y axis).
*Calculate the distance from the telepad to the GPS as sqrt(X^2 + Y^2)
*Multiply it by 10 and extract sqare root.
*What you see at your calc now is power minus offset. As the power was set to 20, to find offset, you need to substract the number you've got from 20. So, for example, if you got roughly 17, the offset is 3 (remember it can be only integer).

Now, to find the bearing offset. When you teleported the GPS, you might've noticed it didn't go precisely north, although the bearing was set to 0. The bearing offset is to blame. Once again, assume the GPS travelled X tiles west and Y tiles north. Then, by dividing X by Y, you get the tangent of the offset angle, and the angle itself can be calculated as '''offset = atan(X/Y)''' (it's also integer, so feel free to round). Given the GPS travelled '''west''', that will be a positive offset that will be added to your bearing, so you have to compensate by substracting it from the bearing you will be setting. Inversly, if the GPS has gone '''east''', the offset is negative and you need to add it to the bearing.
==Steps 2-4, in detail==
Alright, so now you have some values. Time to plug that shit into the equations.


Congratulations! Now that you know both offsets, you can teleport anything with some deadly precision or steal some high-secure items in the most stealthy fashion without having anyone see the GPS tools dancing around! So, how do you put that knowledge to use? Let's assume you want to teleport something X tiles west and Y tiles north. First, you again need to find the distance as '''sqrt(X^2 + Y^2)''' (let's designate it '''D'''). Now, set the power setting so that '''((power-offset)^2)/10''' (let's designate that number as '''Dmax''') was greater than your distance. (If you can't, you need to find you more bluespace crystals). Now, once the power is set, you need to adjust the bearing. '''Divide D by Dmax'''. As Dmax is greater, you'll get a number less than 1. You need to '''calculate the inverse sine from that number and then divide it by 2'''. In one formula,
For the purposes of this article, the GPS that we teleported ended up at 184, 137. The distance the GPS traveled is 40.01249804748511''ish'', or the square root of 1,601. The bearing, elevation, and power were 0, 45, and 20, respectively.
*elevation = (asin(D/Dmax))/2.
Now the bearing setting is obviously dependant not only on the distances the object has to travel along the X and Y axes, but on the general direction it travels to or from (northeast, southeast, southwest, northwest). To set the bearing, you'll need to calculate '''atan(X/Y)''' if the destination is northeast or southwest, and '''atan(Y/X)''' otherwise. Both X and Y numbers here have to be positive (just the distances on X and Y axes without signs). (Writer's note: wish I could add a picture of trigonometric circle in here, that would explain everything much better than I can in words). You'll get a number between 0 and 90, which will be your bearing plus(or minus) offset if you're sending northeast. To send something along the same distances on X and Y, but in the other direction, you'll need to add a multiple of 90 degrees to it. So:
*To send north and east, don't add anything.
*To send south and east, add 90.
*To send south and west, add 180.
*To send north and west, add 270.
Now compensate for the bearing offset, punch those numbers in the computer and hit that Send (or Recieve) button! If you're not miscalculated and everything was done right, you should now have DAT FUKKEN DISK on the telepad or a maximum-yield bomb at the AI core. Enjoy your near-omnipotence, you've truly deserved it.

Sadly, every 30 to 40 teleportations (roughly) the [[Telepad]] will '''fizzle'''. This means you need to click  Recalibrate and start from step 1. Learn to recalibrate quickly, or you may end up in a heap of trouble.
First thing we're going to do is plug the numbers we have into the DestinationX and DestinationY equations to determine the bearing offset.


Leave handy beacons around the station, and GPS units at interesting locations in space, and you can easily find them again. It's worth putting something down in the [[Medbay]] so you can quickly send the wounded and the dead there.


Also, note that the maximum radius you can reach is proportional to power squared, so, with so much as three or four extra crystals, your reach extends immensely. Just insert them into the console and higher power will become available. This also amplifies the recharge time between teleports and the energy the telepad consumes from the room's APC.
