摘要： The method of the invention, which is applicable, in particular, to making positioning signals from GPS and SBAS satellites reliable, consists in performing an instantaneous statistical analysis (of around 1 mn duration) of the correlation peak from the satellite signal receiver and in comparing it to a long-term (several hours) statistical analysis by choosing 5 points which are characteristic of the peak (prompt, ±0.044 and ±0.088). If the result of the comparison exceeds a given threshold, the corresponding signals are rejected.

摘要： A satellite positioning receiver with integrity check and exclusion of defective axes. In order to improve the reliability of the measurements which are divergent with respect to the measurements provided by the other satellites in the constellation which is used at a given time. The invention proposes a solution for more rapidly recalculating the position by eliminating the data from a defective satellite: the means for calculating the position vector X on the basis of n satellites include an iteration process with n steps, the jth step involving the jth satellite; a position X′ is recalculated using only n−1 satellites on the basis of the n steps already calculated, by adding an (n+1)th iteration step, using the measurements from the defective satellite of rank m, this last step being slightly different from the previous ones and the difference being such that the calculation result after this (n+1)th step is identical to that which an iteration with n−1 steps excluding the divergent satellite of rank m would give.

摘要： A satellite positioning receiver with velocity calculation integrity check. In order to increase the reliability of the velocity measurements by the receiver, it is proposed to measure the divergence between the measurements taken on n satellite director axes (n>4) and to given an alarm if this divergence exceeds a predetermined threshold. The divergence is measured by the mean square error between the calculated velocity vector and the velocities as measured along the director axes and projected on to the calculated velocity vector.

摘要： A GPS satellite signal receiver fitted on an aircraft. Velocity measurements are used to obtain position values at a sufficient rate to provide position extrapolation while waiting for the next position measurement. A corrected position is provided on the basis of a measured position by adding to the preceding corrected position, the velocity integrated between two times and a smoothing term which is a fraction of the difference between the measured position and the corrected position at the preceding position measurement time.

摘要： A satellite signal GPS receiver which is located at a fixed station on the ground. The receivers are used in differential position measurement systems. In order to eliminate as much as possible the influence of multipaths on the precision of the measured position, it is detected whether the position measurements are coherent with the velocity measurements, The coherence is measured by the variations in the difference Vi−dPRCi/dt, where Vi is the relative velocity measured along the axis of the ith satellite and dPRC/dt is the time variation of the measured position. If the coherence is not sufficient, the position variation should not correspond to the measured velocity. The measurement of this satellite is then considered to be tainted with error and the satellite is eliminated. In the absence of multipaths, the above difference should be seen to vary periodically. This variation may be detected by a Fourier transform on a sufficient number of measurement samples.
