Global Navigation Satellite Systems (GNSS) - Attacks and Countermeasures

Increasing numbers of mobile computing devices, user-portable, or embedded in vehicles, cargo containers, or the physical space, need to be aware of their location in order to provide a wide range of commercial services. Most often, mobile devices obtain t ...

Performance Comparison of UWB Impulse-Based Multiple Access Schemes in Indoor Multipath Channels

Pierre-André Farine, Cyril Botteron, Paul Saad

In this paper, we consider an impulse-based ultrawideband (UWB) receiver and assess the performance of different multiple access and modulation schemes, including time-hopping pulse position modulation (TH-PPM), time-hopping binary phase shift keying (TH-B ...

Cooperative Localization for Autonomous Underwater Vehicles

Alexander Bahr

The absence of GPS underwater makes navigation for Autonomous Underwater Vehicles (AUVs) a difficult challenge. Without an external reference in the form of acoustic beacons at known positions, the vehicle has to rely on proprioceptive information obtained ...

A Galileo E1b,c RF front-end for Search-and-Rescue applications

Pierre-André Farine, Cyril Botteron, Frédéric Chastellain, Marcel Baracchi Frei, Davide Manetti

The current Search-and-Rescue (SAR) service, which is based on the Cospas-Sarsat system, suffers from major limitations such as poor position accuracy, long alert times and high false alarm rate. Two types of distress signals are used, the 121.5MHz/(up to ...

Development, implementation and validation of a real-time Galileo E1-B signal acquisition and tracking scheme

Pierre-André Farine, Cyril Botteron, Frédéric Chastellain, Marcel Baracchi Frei, Davide Manetti, Giuseppe Zamuner, Elham Firouzi

With the introduction of a square wave sub-carrier modulation in the Galileo E1 BOC(1,1) open service signal, the autocorrelation function becomes more complex as compared to the GPS L1 C/A BPSK(1) signal. Indeed, the presence of two secondary side lobes i ...

Development of a robotic mobile mapping system by vision-aided inertial navigation

Fadi Atef Bayoud

Vision-based inertial-aided navigation is gaining ground due to its many potential applications. In previous decades, the integration of vision and inertial sensors was monopolised by the defence industry due to its complexity and unrealistic economic burd ...

A Galileo E1b,c RF Front-End Optimized for Narrowband Interferers Mitigation

Pierre-André Farine, Cyril Botteron, Frédéric Chastellain, Davide Manetti, Giuseppe Zamuner

The current Search and Rescue (SAR) service, which is based on the Cospas-Sarsat system, suffers from major limitations such as poor position accuracy, long alert times and high false alarm rate. Two types of distress signals are used, the first 121.5MHz/( ...

Mobile User Navigation Supported by WSAN: Full-fledge Demo of the SmartPark System

Matthias Grossglauser, Aristidis Papaioannou

The purpose of this demonstration is to illustrate that an off-the-shelf Wireless Sensor and Actuator Network (WSAN) can be used to discover resource availability and guide mobile users to these resources without any support from a navigation system like G ...

Bayesian Inference for Autonomous Personal Localisation Indoors

Michel Bierlaire, Bertrand Merminod

The principal concept of navigation is to start from a known (initial) position and to ensure a continued and reliable localisation of the user during his/her movement. The initial position of the trajectory is usually obtained via GPS or defined by the us ...
