Power-Optimized Digitally Controlled Oscillator in 28-nm CMOS for Low-Power FMCW Radars
Christian Enz, Francesco Chicco, Franz Xaver Pengg, Sammy Cerida Rengifo
This work presents the design of a 24-GHz digitally controlled oscillator (DCO) in an advanced 28-nm bulk CMOS technology for short-range frequency-modulated continuous-wave radar system-on-chip for mobile and Internet-of-Things devices. The power minimiza ...
IEEE-INST ELECTRICAL ELECTRONICS ENGINEERS INC2021QUIC: Opportunities and threats in SATCOM
Emmanuel Qays Dubois, Ludovic Bernard Gérard Thomas
This article proposes a discussion on the strengths, weaknesses, opportunities and threats related to the deployment of QUIC end-to-end from a satellite-operator point-of-view. The deployment of QUIC is an opportunity for improving the quality of experienc ...
IEEE2020Doppler-based positioning using LEO augmented satellite constellation - Simulations of perspectives
The Global Navigation Satellite System (GNSS) refers to a constellation of satellites emitting signals from space, used to provide Position, Navigation and Timing (PNT) services to the receivers on Earth. Nowadays, the GNSS is exploited in a wide range of ...
2020Small satellites for space science A COSPAR scientific roadmap
Volker Gass, Jie Wu, Maurice Borgeaud
This is a COSPAR roadmap to advance the frontiers of science through innovation and international collaboration using small satellites. The world of small satellites is evolving quickly and an opportunity exists to leverage these developments to make scien ...
ELSEVIER SCI LTD2019Calibration Aspects of INS Navigation
The use of a Bayesian filter (e.g., Kalman filter) for the fusion of information from satellite positioning and inertial navigation is a common approach in many applications, where the knowledge of position, velocity, and attitude in space are of great int ...
EPFL2019Comparison of L1 and L5 Bands GNSS Signals Acquisition
Cyril Botteron, Jérôme Leclère
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 ...
2018Hypervelocity impact testing on stochastic and structured open porosity cast Al-Si cellular structures for space applications
A hypervelocity (6.7–7.0 km/s) impact testing campaign was conducted using Ø 2 mm, 95% Al projectiles onto A357 aluminium alloy stochastic foams with 4–5 mm typical pore dimensions, or alternatively diamond cubic periodic structures of cast AlSi12 with a 6 ...
2018Radio Resource Management Optimization of Flexible Satellite Payloads for DVB-S2 Systems
The increasing demand for high-rate broadcast and multicast services over satellite networks has pushed for the development of high throughput satellites characterized by a large number of beams (e.g., more than 100). This, together with the variable distr ...
20173D-printed Ka-band Antenna Based on Stereolithography
Juan Ramon Mosig, Tomislav Debogovic, Maria Garcia Vigueras, Joana Rita Alves dos Santos Silva
This paper presents a circularly-polarized dual-band antenna for Ka-band satellite communications which operates simultaneously in both civil and military downlink (17.7-21.2 GHz) and uplink (27.5-31 GHz) bands. The antenna is composed of a metallic ridged ...
IEEE2017CubeSat quantum communications mission
Quantum communication is a prime space technology application and offers near-term possibilities for long-distance quantum key distribution (QKD) and experimental tests of quantum entanglement. However, there exists considerable developmental risks and sub ...
