Abstract: A method and system for estimating a position of a mobile device is disclosed. In particular, a method and system in which the position of a mobile device is determined using measurements of received Global Navigation Satellite System, GNSS, satellite signals is disclosed. The present invention therefore proposes to qualify a received satellite signal based on whether a signal propagation characteristic of this signal falls within an expected range of this characteristic. The expected range is determined using information about the satellite that sent the signal. The position of the mobile device is computed based on the validated satellite signals.

Abstract: A method for generating a panoramic image includes providing a 3D point model of an area surrounding a virtual viewpoint, acquiring multiple images of the area surrounding the virtual viewpoint, projecting the acquired images onto the 3D point model and generating the panoramic image using the thus obtained 3D point model of the surrounding area.

Abstract: A method for producing hydrocarbon fluid, such as crude oil and/or natural gas, through a well or well cluster of which the trajectory is at least partly defined and iteratively optimized by an well trajectory optimization algorithm that is coupled to a finite difference reservoir simulation program that represents a hydrocarbon fluid containing reservoir as a set of grid cells with a specified permeability and fluid content, wherein the algorithm: provides a virtual well with a series of virtual well branches that extend into cells in the vicinity of inflow points of the virtual well; and subsequently iteratively moves the inflow points of the virtual well or well cluster through the reservoir in order to optimize a reservoir depletion strategy that provides an optimized life cycle value of the well and/or well cluster and/or optimized Net Present Value (NPV) of the produced crude oil and/or natural gas.
