Son but est uniquement de collecter et de recommander des références pertinentes à des contenus que vous pouvez explorer pour vous aider à répondre à vos questions.

Nowadays, global navigation satellite systems (GNSSs) are used for many new applications that go further than the original goal of providing position, velocity and timing for land, maritime and air applications. In particular, GNSS receivers have been adop ...

This paper brings additional light on the previously proposed two-step tracking algorithm for E1 CBOC tracking. More specifically, assessment of the different DLL and PLL tracking loop architectures are analyzed, taking into consideration coherent and non- ...

The acquisition of Global Navigation Satellite Systems signals using Code Division Multiple Access can be performed through classical correlation or using a Fourier transform. These methods are well known but what is missing is a comparison of their perfor ...

The design of a programmable receiver for an ultra wideband (UWB) communication is presented. The receiver is using a fast analog to digital converter (ADC) and a field programmable gate array (FPGA) allowing a rapid performance evaluation for various syst ...

This paper describes a generalisation of the aeronautical GNSS Space Based Augmentation System (SBAS) air interface, in a true worldwide multimodal standard named Universal S-BAS. Examples of usages of this multifrequency future standard are presented in t ...

Nowadays, civil Global Navigation Satellite System (GNSS) signals are available in both L1 and L5 bands. A receiver does not need to acquire independently the signals in both bands coming from a same satellite, since their carrier Doppler and code delay ar ...

Global Navigation Satellite Systems (GNSSs) were originally introduced to provide positioning and timing services for terrestrial Earth users. However, space users increasingly rely on GNSS for spacecraft navigation and other science applications at severa ...

It is well known that reflected signals from Global Navigation Satellite Systems (GNSS) can be used for altimetry applications, such as monitoring of water levels and determining snow height. Due to the interference of these reflected signals and the motio ...

In this work, we evaluate the exploration of the Solar system by ad-hoc wireless sensor networks (WSN), i.e. networks where all nodes (either moving or stationary) can both provide and relay data. The two aspects of self-organization and localization are t ...

GNSS platforms such as the American Global Positioning System (GPS) or the Russian GLONASS system are being continuously updated with new satellites offering new signals, new frequencies and new functionalities. Moreover, new GNSS systems such as the Europ ...

The invention concerns a wireless data communication method, wherein a transmitter device (2) having a first broadband antenna (27) transmits ultra wideband coded data signals to a receiver device (3) having a second broadband antenna (37) for receiving th ...

The invention relates to a method for identifying a datum Sk that includes: a) constructing (84) a chronological series {T1;...; Ti;...; TN} of the arrival times Ti of consecutive pulses or pulse blocks; b) calculating (96) a resemblance value among said s ...

Roads right across Europe are becoming more congested and governments and regional authorities are looking for ways to better manage the existing road network. One tool that is being increasingly promoted to tackle the congestion challenge is Road User Cha ...

Multipath mitigation in urban canyons and indoor environments is an open issue for the reception of GNSS signals for high precision applications, as the presence of multipath components can lead to signal fading and ranging errors. New families of navigati ...

The introduction of new modulations on the global navigation satellite systems brings potential improvements for ground positioning. Clever receiver designs taking advantage of the characteristics of the new signals will be able to achieve better accuracy, ...

This paper deals with the design of a 4-channel phased-array receiver Front-End (FE) architecture working at 24 GHz. Targeting low power applications such as radar sensors and medium bit-rate transceivers, a local oscillator shifting architecture is propos ...

Today it is possible to achieve sub-ns level time synchronization on a wireline network while only us-level synchronization can be achieved on a wireless (microwave) link. In this paper we will, first, study the performances of different time synchronizati ...
