In this paper, we address the issues of the representation of boreal fires in a global chemistry and transport model (GEOS-Chem) as well as their contribution to the Arctic aerosol optical thickness and black carbon (BC) deposition, with a focus on the 200 ...
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 ...
In pedestrian user environments, like dense urban canyons or indoors, the GNSS positioning performance regarding accuracy and availability reaches well-known technological limits. These limitations can be overcome by adding additional sources of informatio ...
The incommensurately modulated twinned crystal structure of lazurite from the Baikal region is presented for the first time. The orthorhombic structure was solved in a pseudo cubic unit cell, a(cub) = 9.077(1) Angstrom, and in the (3 + 2)D superspace group ...
In this paper, a software tool for the prediction of the corona discharge and the multipactor thresholds in passive components based on rectangular geometry for space applications is presented.The software tool has been compare to measurements showing a ve ...
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 ...
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 ...
The main objective of the project ‘SARHA - Sensor-Augmented EGNOS/Galileo Receiver for Handheld Applications in Urban and Indoor Environments’ is the development of a modern satellite navigation receiver with autonomous sensor augmentation. Additionally, t ...
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 ...
