An acoustic technique for propellant gauging
(2022)
Conference report
Restricted access - publisher's policyThe gauging of propellants in upper stages or satellites in orbit is a challenging task due to the absence of buoyancy, which makes liquids and gases adopt a large variety of configurations. The new Spectral Mass Gauging ... -
Heat transfer management in propellant tanks
(2022)
Conference report
Restricted access - publisher's policyA critical issue in long-term space exploration missions is the storage and management of cryogenic propellants. Storage tanks are exposed to extreme temperatures and radiation, and hot spots might appear on the tank walls ... -
Integrated acoustic technology for boil-off control, mass gauging, and structural health monitoring in cryogenic fuel tanks
(2022)
Conference report
Restricted access - publisher's policyLong-term space exploration missions require efficient systems for cryogenic propellant storage and management. The exposure of the fuel tanks to the in-space operational environment implies the need for efficient technologies ... -
The Mechanism for GNSS-Based Kinematic Positioning Degradation at High-Latitudes Under the March 2015 Great Storm
(2022-06)
Article
Open AccessIn this study, we focus on the kinematic precise point positioning (PPP) solutions at high-latitudes during the March 2015 great geomagnetic storm. We aim to discover the mechanism behind the positioning degradation from ... -
Volcanic eruption of Cumbre Vieja, La Palma, Spain: A first insight to the particulate matter injected in the troposphere
(Multidisciplinary Digital Publishing Institute (MDPI), 2022-05-20)
Article
Open AccessThe volcanic eruption of Cumbre Vieja (La Palma Island, Spain), started on 19 September 2021 and was declared terminated on 25 December 2021. A complete set of aerosol measurements were deployed around the volcano within ... -
Interferometric SAR deformation timeseries: a quality index
(International Society for Photo-Optical Instrumentation Engineers (SPIE), 2021)
Conference report
Open AccessEstimating unknown absolute phase from a wrapped observation is a challenging and ill-posed problem that possibly leads to misinterpretation of interferometric SAR (InSAR) deformation results. In this study, we introduce ... -
Status and trends of wetland studies in Canada using remote sensing technology with a focus on wetland classification: a bibliographic analysis
(Multidisciplinary Digital Publishing Institute (MDPI), 2021-10-09)
Article
Open AccessA large portion of Canada is covered by wetlands; mapping and monitoring them is of great importance for various applications. In this regard, Remote Sensing (RS) technology has been widely employed for wetland studies in ... -
A secure broadcast service for LDACS with an application to secure GBAS
(Institute of Electrical and Electronics Engineers (IEEE), 2021)
Conference report
Open AccessThe VHF Data Broadcast (VDB) data link is responsible for transmitting Ground Based Augmentation System (GBAS) corrections from the GBAS ground station to the aircraft. Thus, it is a major bottleneck for the evolution and ... -
LES study of the impact of fuel composition on a swirl spray flame approaching blow-off
(2021)
Conference lecture
Open AccessThe present paper focuses on the large eddy simulation (LES) of the n-heptane and n-dodecane flames of the Cambridge swirl flames data repository (Sidey et al., 2017). The applied tabulated chemistry spray combustion model ... -
Assessment of chemistry reduction in high-pressure spray flames of oxymethylene ethers using large-eddy simulations
(2021)
Conference lecture
Open AccessThis study is focused on the numerical investigation of reduced chemical schemes for high pressure spray flames of oxymethylene ethers (OMEx). A reduced mechanism using Path Flux Analysis (PFA) technique is tested using ... -
Detection of GNSS multipath with time-differenced code-minus-carrier for land-based applications
(IEEE Press ; Wiley, 2020)
Conference report
Open AccessGround transportation systems demand accurate and robust localizationfunctions. Satellite navigation is considered a key element in those systems, but its position determination can be highly corrupted in urban environments ... -
Performance analysis of the IOPES seamless indoor-outdoor positioning approach
(2021-06-30)
Article
Open AccessTracking the members of civil protection or emergency teams is still an open issue. Although outdoors tracking is routinely performed using well-seasoned techniques such as GNSS, this same problem must be still solved for ...
