    We"re looking for someone with skills in mathematics in first hand. If you"re experienced in programming it"s a big plus. It doesn"t matter in what language you"re skilled in. We can adopt. The key here is the mathematics. The kind of math that"s involved is to calulate geographic positions based on facts like time and signal strengs. Trilateration gives a good idea to the task.We have a databased with signal strengths and exact time of the measurements. Based on these fact we need to calculate a geographic position. We have all the data needed. We need someone to help us with calculations and suggestions for better precision.This is a very exciting project and can be a long term project if we like each other. :)
