For the universities of the emergent countries, and those of Cameroon in particular, the fight to reach a durable development requires to know the needed scientific and technical information for their development, how to get it and to spread it out among p ...
The Inertia Wheel Assembly (IWA) is composed by the IWA motor, the inertia wheel and the command electronics. IWA belongs to the Attitude Determination and Control System (ADCS) of the SwissCube satellite. Swisscube is a pico-satellite that complies with C ...
As with a growing number of athletes, competitive skiers are looking to GNSS technology to help evaluate and improve their performance. Positions logged during practice runs or races can be transformed into 3-D models of the exact trajectories skied to mea ...
With the inclusion of 406 MHz transponders on the Galileo satellites and the new search and rescue (SAR) return link message (RLM) on the open service E1B signal, the availability of distress beacons equipped with a Galileo or combined GPS/Galileo receiver ...
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 ...
The personal positioning and navigation became a very challenging topic in our dynamic time. The urban canyons and particularly indoors represent the most difficult areas for personal navigation problematic. Problems like disturbed satellite signals make t ...
Inertially aided satellite positioning can bring its benefits to all disciplines in which detailed knowledge of the trajectory is a prerequisite for improving performance. In motorcycling for instance, the determination of slips of tires requires the deter ...

The goal of this project is to develop and build an electric motor to drive the inertia wheel of the SwissCube satellite. This system should provide angular stability to the satellite and allow its control. The operational speeds range from 5000 to 11 000 ...
An implementation of a dynamic supply RF power amplifier (PA) in 0.11 mu m CMOS technology occupying a total area of 1.35mm(2) is presented. Two-tone measurement results at 2.4 and 5.2GHz show that the system can deliver over 16dBm linear output power with ...
