摘要：In the present invention, a conditional probability distribution function ofreceived signal which is conditioned with a received signal amplitude (a), a pseudo range(p) and a navigation bit (bm) which are unknown parameters is acquired from a GPS signalsample S2 on the basis of a condition defined by a working hypothesis set in a workinghypothesis setting part WH(i) and then the conditional probability distribution function(P(Rm a, p, bm)) is marginalized with respect to the pseudo range (p) to acquire amarginal posterior probability distribution function (P(p | Rm, a)) in a step ST11. Finallyacquired is a pseudo range dependent function in proportion to the marginal posteriorprobability distribution function (P(p | Rm, a)). Then, in a step ST12, a value of pseudorange (p) which gives the maximum value of pseudo range dependent function isdetermined as an estimated pseudo range.
