Abstract: In the proposed method of radio satellite localization of points on the surface of the earth:a pseudolite transmitter (1) is placed on a masked point (P);the antenna (3) of radio localization means (2) is placed successively in a plurality of arbitrary points (P.sub.i) where reception of the signals transmitted by the satellite is satisfactory, and the phase of the signal transmitted by the pseudolite transmitter (1) and received by the antenna at said points is measured; andthe coordinates of the masked point (P) is determined as a function of said measurements and as a function of the coordinates of the points (P.sub.i).The apparatus includes a pseudolite transmitter (1) and a radio localization mobile receiver (2) having one of its channels allocated to receiving the signal (S.sub.p) transmitted by the pseudolite transmitter (1).

Abstract: A method of staking out a point on the ground using a satellite positioning system comprises the following steps: two reference points near a target point are marked on the ground and the positioning system antenna is located on each of the two points to determine their coordinates, the position of the target point relative to the two reference points is determined from these coordinates, the point corresponding to this relative position is marked on the ground, and the staking out is done at this point. The device for implementing the method includes arrangements for marking the two reference points and the target point on the ground.
