The word to look for is multilateration. Wikipedia has an article on
it:

https://en.wikipedia.org/wiki/Multilateration

Calculating the time differences based on a known position is
relatively simple. Once you try to solve the equations to go the other
way, the math gets ugly.

Years ago, when I was playing with this, I resorted to a numerical
solution.
