摘要： A process for determining the position of a moving object, by the following steps: scalar measurements are acquired by a set of sensors all installed on the same site, at a position known at each instant; the trajectory of the object is determined approximately by a model; the measurements output from each sensor are combined to obtain spatial gradient measurements representative of the vector electromagnetic disturbance of the moving object; a vector of parameters characteristic of the model is estimated as a function of gradient measurements and as a function of the position of the sensors; and the position of the object is determined as a function of the position of the sensors and the parameters vector.

摘要： A process for the extraction of a time-variable useful signal having a finite spatial extension by an array of N sensors or transducers (N being equal to or greater than 3), that receive the useful signal to which have been added q spatially coherent additive noises (q being less than N). According to the process, unprocessed signals are acquired on the output of each sensor, filtered in order to restrict them to the frequency band of the useful signal and digitized. Then, spatial prediction error signals of the noise are calculated and analyzed so as to carry out the detection of the useful signal and its separation from the q additive noises. A device for extracting a useful signal according to the process is also disclosed.

摘要： In a magnetic cartography process and apparatus, measurements are performed by magnetic field sensors placed in "fish" moved in the area to be mapped. Gradients are determined on the basis of the difference between the measurements supplied by two sensors at the same time, this applying to any pair of sensors, and/or on the basis of the difference between the measurements supplied by the same sensor at two different times, this applying to any sensor, which leads to at least one map of gradients which is broken down into a map of regional field gradients and a map of local field gradients. On the basis of the local field gradients, a determination takes place of the geological field relative to the area, or the gradients of the field and then the local field, by adding the geological field to the regional field determined on the basis of its gradients by an inversion and direct calculation method.

摘要： A system and method for estimating the orientation of an object in space at the instant k using measurements of the total acceleration (yA), of magnetic field (yM) and of the speed of rotation (yG) of said object in relation to three space axes, comprising a step of preprocessing said measurements (yA, yM, yG) at an instant k so as to detect the existence of a disturbance in said measurements and to compute corrected measurements at the instant k and a step of estimating the orientation ({circumflex over (q)}k) at the instant k by an observer on the basis of the corrected measurements ({tilde over (y)}A,k, {tilde over (y)}M,k, {tilde over (y)}G,k) at the instant k obtained from the preprocessing step. The estimation step advantageously uses matrices for transforming the frame of the object into a fixed frame which are applied, in case of disturbance, to a quaternion deduced from the integration of a measurement of speed of rotation composed with a quaternion of orientation computed at the instant k−1.
