If the three reference points are all on a two-dimensional surface and aren't all on exactly the same line, then yes: this is sufficient to find your origin point. The technical term for the method that you're describing is trilateration.

Thanks for your help ,

My basic math is ok but as i get older i seem to get more interested in more complex stuff and unfortunately didnt seem to have the same interest when i was younger and it mattered

Is there an equation that is readily available to solve such problems.

Any help would be much appreciated.

The problem i am trying to get to the bottom of is one of sporting nature. It involves the distances flown from a racepoint (latitude longitude unknown)

to three different locations both distance and lat long known for these , I am trying to find the lat long of the race point.

Thanks in advance
