摘要： An evaluation point E of a present position candidate corresponding to each satellite set is calculated based on an a priori residual (APR) (APR value), a PDOP value, and the number of satellites of the target satellite set according to E=k1·f1(APR)+k2·f2(PDOP)+k3·f3(number of satellites). Evaluation coefficients k1 to k3 for respectively weighting evaluation functions f1 to f3 are determined based on an APR average value.

摘要： In the first positioning, a positioning process that calculates the present position based on acquired GPS satellite signals (step A3) is performed a plurality of times. A number of times that the difference (position difference) ΔP between the calculated present located position and the preceding located position is successively equal to or less than a given value is counted using a position counter, and a number of times that the difference (time difference) ΔT between the present time error and the preceding time error is successively equal to or less than a given value is counted using a time counter each time the positioning process is performed (step A5). A position threshold value and a time threshold value are determined by changing a reference threshold value by an amount corresponding to an APR average value (step A7). When the position count value has reached the position threshold value (step A9: YES) and the time count value has reached the time threshold value (step A11: YES), the present position is determined to be the first located position and output (step A13).

摘要： Estimation calculations for calculating an estimated present position are performed twice corresponding to each satellite set. The estimated present position calculated by the second estimation calculations is determined to be a present position candidate corresponding to the target satellite set. In the first estimation calculations corresponding to the first satellite set, the calculated satellite position and estimated pseudo-range of each GPS satellite are stored in caches. In the second estimation calculations, the satellite position of each GPS satellite is read from the cache. In the first estimation calculations corresponding to the second or subsequent satellite set, the satellite position and the estimated pseudo-range of each GPS satellite are read from the caches, and the satellite position and the estimated pseudo-range of the GPS satellite of which the satellite position and the estimated pseudo-range have not been stored in the caches are calculated and stored in the caches. In the second estimation calculations, the satellite position of each GPS satellite is read from the cache.
