A user computing device, method and computer program to display a view to the user are provided. The invention allows a user to display a number of different views with photorealistic rendering of how the view should look like at a view time, based solely on view position, and descriptors of the view. In an aspect, the invention deduces from view position and view time the view descriptors (weather parameters, traffic parameters . . . ); selects, in a collection of images, an image of the view based on view position; modifies the image to match descriptors of the view (for example, by adding a rain effect if the image in the collection is under sunshine and the view should be displayed under rain). Thus, the invention allows displaying photorealistic images of how a view should look like at any time.

The invention relates to a method and a device for measuring at least one atmospheric parameter (gas, temperature), implementing steps of acquiring spectral images in the ultraviolet and/or the visible and/or the infrared range and scanning according to a tomographic principle. The spectral images are acquired using a network of optical systems (1A-1D) such as infrared cameras, and are used to estimate the air quality and/or meteorological and/or climate parameters in a geographic area, for example an urban agglomeration.

The invention discloses a receiver and a method to process navigation signals from one or more GNSS constellation, wherein an observation model and a measurement model allow a direct calculation of the carrier phase ambiguities. More specifically, in a triple frequency implementation, the receiver calculates in turn the extrawidelane, widelane and narrowlane ambiguities. The code and carrier phase biases can also be directly calculated. Thanks to the invention a quicker acquisition and tracking of a precise position, which will also be less noisy than a prior art solution, especially in some embodiments of the invention using a RAIM and/or a gap-bridging function. Also, code smoothing using the Doppler and low latency clock synchronization allow to decrease the noise levels of the precise point navigation solutions.

Abrégé
The invention relates to a device for the frequency transposition of an input signal centred on a frequency (f1) to an output signal centred on a frequency (f2). Such a device comprises a module for averaging the input signal delivering a set of N first intermediate signals. A first intermediate signal of index (i), where i is a whole number from 1 to N, is a function of an i-th sliding average of the input signal over an i-th first time window of the form [(i-1)/(N*f1); i/(N*f1)] periodised at the frequency (f1). The device also comprises a module for reconstructing the output signal by temporal concatenation of N second intermediate signals windowed in second successive time windows. A second intermediate signal of index (k), where k is a whole number from 1 to N, is obtained from a windowing of the first intermediate signal of index (k) in a k-th second time window of the form [(k-1)/(N*f2); k/(N*f2)] periodised at the frequence (f2).
