Contribution to the Worldwide multimodal SBAS standard

Pierre-André Farine, Cyril Botteron, Aleksandar Jovanovic, Youssef Tawk

Several studies have been done or have been started in order to extend the current aeronautical Space Based Augmentation System (SBAS) DO-229D Minimum Operational Performance Specification (MOPS) SBAS standard mainly defined by the Radio Technical ComiteeC ...

NEARCTIS - Role of technologies: Positioning and Communication

Pierre-Yves Gilliéron

Positioning, tracking and communication (PTC) systems are the basic components of cooperative systems, and it is their development in recent years that has in turn made possible the idea of cooperative systems. The ongoing developments of GNSS (Global Navi ...

Fabrication and Testing of a MEMS Based Earth Sensor

Herbert Shea, Kaustav Ghose

We present a novel MEMS inertial sensor that directly measures the gravity gradient in order to sense the relative orientation of a satellite with respect to the Earth. An Earths ensor provides an orbiting satellite with a vector towards the Earth center. ...

A micromachined earth sensor based on measuring the gravity gradient torque

Herbert Shea, Kaustav Ghose

We present the fabrication and testing of a novel MEMS inertial sensor that directly measures the gravity gradient in low Earth orbit in order to sense the relative orientation of a satellite with respect to the Earth. Instead of the current Earth sensing ...

Optimization of two GPS/MEMS-IMU integration strategies with application to sports

Jan Skaloud, Adrian Wägli

The application of low-cost L1 GPS receivers integrated with micro-electro-mechanical system (MEMS) inertial measurement units (IMU) allows the continuous observation of position, velocity and orientation which opens new possibilities for comparison orf at ...

MEMS FOR SPACE

Nico de Rooij, Danick Briand, Herbert Shea, Sebastian Gautsch, Wilfried Noell

Future space exploration will emphasize on cost effectiveness and highly focused mission objectives. Missions costs are directly proportional to its total weight, thus, the trend will be to replace bulky and heavy components of space carriers, communicatio ...

Improving pedestrian dynamics modelling using fuzzy logic

Kamiar Aminian, Bertrand Merminod, Phillip Tomé, François Bonzon

The complementary nature of MEMS based pedestrian dead-reckoning (PDR) navigation and GNSS (Global Navigation Satellite System) has long been recognised. The advantages are quite clear for those applications requiring indoor positioning and that, for one r ...

GNSS-based Positioning: Attacks and Countermeasures

Panagiotis Papadimitratos, Aleksandar Jovanovic

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 ...

Satellite Communications: Internet Challenges and Low-latency Applications

Igor Bilogrevic

This paper analyzes several mitigation strategies and techniques that could enable delay sensitive applications to work properly over satellite IP networks. A study is conducted on different satellite classes (GEO, MEO and LEO) and the analysis of the curr ...
