Abstract :
A mechanical analog simulator for converting hyperbolic coordinates into rectangular coordinates for a short-range hyperbolic position-fixing system is described. The instrument caters for a range of about 40 km and a design accuracy of 0.5 per cent. The measured accuracy is discussed and compared to the theoretical predictions for the simulator. The station configurations with the least error magnification are discussed.
