The Near-Infrared Spectrometer and Photometer (NISP) on board the Euclid satellite provides multiband photometry R>=450 slitless grism spectroscopy in 950-2020nm wavelength range. In this reference article we illuminate background of NISP's functional calibration requirements, describe instrument's integral components, provide all its key properties. We also sketch processes needed to understand how NISP operates is calibrated, technical potentials limitations. Links articles providing more...
User requirements for the performance of Global Navigation Satellite System (GNSS)-based road applications have been significantly increasing in recent years. Safety systems based on vehicle localization, electronic fee-collection systems, and traveler information services are just a few examples interesting requiring onboard equipment (OBE) capable offering high available accurate position, even unfriendly environments with low satellite visibility such as built-up areas or tunnels at cost....
Lane-level positioning and map matching are some of the biggest challenges for navigation systems. Additionally, in safety applications or those with critical performance requirements (such as satellite-based electronic fee collection), integrity becomes a key word community. In this scenario, it is clear that system can operate at lane level while providing parameters capable monitoring quality solution bring important benefits to these applications.

The concept of enhanced maps (Emaps) was introduced with one main objective: It should characterize roads, first, more completeness and, second, accuracy than standard to fulfill the requirements new challenging road safety applications and advanced driver-assistance systems (ADAS). This paper introduces a paradigm for Emap definition creation on which every lane is represented topologically connected rest lanes. Following this approach, number Emaps have been created in France, Germany,...
Currently, distributed traffic information systems have come up as one of the most important approaches for detecting flow problems on a road. For that purpose, they usually make use location vehicles share among them through periodical messages are transmitted across vehicular ad hoc network (VANET). This paper puts forward an event-driven architecture (EDA) novel mechanism to get insight into VANET detect different levels jams; furthermore, it also takes account environmental data from...
Galaxy cluster counts in bins of mass and redshift have been shown to be a competitive probe test cosmological models.

Euclid's photometric galaxy cluster survey has the potential to be a very competitive cosmological probe. The main probe with observations of clusters is their number count, within which halo mass function (HMF) key theoretical quantity.

Nowadays, it is common that road vehicle navigation systems employ maps to represent the positions in a local reference. The most usual process do consists estimation of positioning by fusing Global Navigation Satellite System (GNSS) and some other aiding sensors data, subsequent projection these values on map applying map-matching techniques. However, possible benefit from information also during data for positioning. This paper presents an algorithm lane-level integrates GNSS,...
In modern weak-lensing surveys, the common approach to correct for residual systematic biases in shear is calibrate shape measurement algorithms using simulations. These simulations must fully capture complexity of observations avoid introducing any additional bias. this paper we study importance faint galaxies below observational detection limit a survey. We simulate simplified Euclid VIS images including and excluding population, measure shift multiplicative bias between two sets with...

The reflections of satellite signals in the environment Global Positioning Systems (GPS) receivers cause significant errors their position estimates. Particularly critical are due to so called non-line-of-sight (NLOS) satellites. In a NLOS situation, only way signal reaches receiver is by means on plane surfaces, typically buildings, causing overestimates pseudoranges between satellites and antenna. Receivers not always distinguish direct multipath effects, leading un-modelled GPS errors....

In physically realistic, scalar-field-based dynamical dark energy models (including, e.g., quintessence), one naturally expects the scalar field to couple rest of model’s degrees freedom. particular, a coupling electromagnetic sector leads time (redshift) dependence in fine-structure constant and violation weak equivalence principle. Here we extend previous Euclid forecast constraints on this enlarged (but more realistic) parameter space, how well , together with high-resolution...

Weak lensing, which is the deflection of light by matter along line sight, has proven to be an efficient method for constraining models structure formation and reveal nature dark energy. So far, most weak-lensing studies have focused on shear field that can measured directly from ellipticity background galaxies. However, within context forthcoming full-sky surveys such as Euclid, convergence maps (mass maps) offer important advantage over fields in terms cosmological exploitation. While it...
One of the main drawbacks global navigation satellite systems (GNSSs) in urban environments is that signals may arrive at receiver antenna only nonline-of-sight (NLOS) conditions, leading to biased pseudorange estimates when they are taken for granted by and, eventually, wrong positioning.
