Hi I am trying to find a way to natively trilateral between three points in ArcMap, using the Distance-Distance construction feature I can do this with two measurements but is there a way to give a third input measurement?

I've also tried buffering each point by the distance and then running an intersect but the issue is, especially with hand collected data, if the records are not 100% accurate you are left with a "cocked hat" where the three circles do not intersect so the point has to be placed manually. this is also quite time intensive when you have multiple fixes to plot.

Use

Mean centertool. mean centerThen use

Point Distancetool to determine the distances from mean center to all 3 points .point distance
