Abstract

PURPOSE:To achieve the miniaturization and cost reduction of the titled apparatus by a simple circuit constitution, by calculating a present position on the basis of timing difference, time difference, the position of a predetermined radio wave transmitting site and a reference position. CONSTITUTION:The radio wave sent out from a radio wave transmitting site PH is received to detect the timing difference (azimuth difference DELTAthetaH) at the present position P2 and reference position P1 of the receiving timing to one revolution of a rotary antenna from which said radio wave is sent out and the time difference DELTAtH between the propagation time of the radio wave before said radio wave is received at the present position P1 and the propagation time before said radio wave is received at the reference position P1. From these azimuth difference DELTAthetaH and propagation time difference DELTAtH, the azimuth angle thetaH+DELTAthetaH when the present position P2 is looked from the site PH and the distance RH+CDELTAtH (C: velocity of light) from the site PH to the present position P2 are obtained and the position coordinates of the present position P2 is calculated as a point present at a predetermined distance from the site PH in a predetermined azimuth.
