Abstract
A satellite-signal reception-processing apparatus for receiving signals, which each have completed a spectrum-spreading process using a spreading code, from a plurality of artificial satellites. Then, on the basis of the received signals, the apparatus computes its own position and velocity. The apparatus includes a position-computation satellite determination section for searching for a set of specific artificial satellites each having its locus known and the time of transmission of its spreading code also known, using this set to compute the position of the apparatus. The apparatus also includes a velocity-computation satellite determination section for searching for a set of particular artificial satellites each having its locus known and the frequency of its carrier determined to be a stable frequency, and using this set to compute the velocity of the apparatus.
