After the geographic parameter is calculated, the result will be stored, whether or not there are other pairs of shots 54 in block 38, and the position is processed in block 56. If there are other pairs of shot two = 2 devices 30 need to be calculated? The rule repeats the blocks 50, 52, and 54 until all the searching device 30 needs to be calculated, and is calculated. The triangulation meter has one pair of geographic coordinates with respect to the 30 frequency direction finding means 30, that is, the source 2 = the result is that the source of the RF signal seeks latitudes in all pairs of RF directions. After the break 30 is calculated and all 578423 invention descriptions (14) are stored, the position processor 38 begins to determine the "best fit" geographic coordinates of 11 ", block 58. The most suitable geographic coordinates It may be determined by simply averaging the coordinates or by taking the weighted average of any obviously τ irregular position information. If one coordinate is far from other coordinates, it may be due to equipment failure or data damage And other reasons, and this has been taken into account and can be compensated. Other statistical models may also be used to determine the most suitable geographic coordinates. The most suitable geographic coordinates have been recorded, assuming it is accurate, and used to determine The street address. The longitude and latitude of the most pleasant geographic coordinates are converted to a street or highway α (highway) address, which is safe for the public: ί? (PSAP) It makes sense for the decision maker, box 60.
