A Toolkit for Localisation Queries
Pervasive and Mobile Computing, 2023 While UbiComp research has steadily improved the performance of localisation systems, the analysis of such datasets remains largely unaddressed. In this paper, we present a tool to facilitate querying and analysis of localisation time-series with a focus on semantic localisation. Drawing on well-established models to represent movement and mobility, we

Simultaneous estimation of ocean mesoscale and coherent internal tide sea surface height signatures from the global altimetry record [PDF]
Ocean Science, 2022 This study proposes an approach to estimate the ocean sea surface height signature of coherent internal tides from a 25-year along-track altimetry record, with a single inversion over time, resolving both internal tide contributions and mesoscale eddy ...

Towards an Open Source Localisation Orchestration Framework
Revista Tradumàtica, 2011 This paper describes the design and implementation of a novel environment for the inter-connectivity of distributed localisation components - both open source and proprietary - in response to the scarcity of relevant research in this area, as we view ...

Data-Driven Calibration Algorithm and Pre-Launch Performance Simulations for the SWOT Mission
Remote Sensing, 2022 The Surface Water and Ocean Topography (SWOT) mission will be affected by various sources of systematic errors, which are correlated in space and in time. Their amplitude before calibration might be as large as tens of centimeters, i.e., able to dominate

Accuracy of the mean sea level continuous record with future altimetric missions: Jason-3 vs. Sentinel-3a [PDF]
Ocean Science, 2016 The current mean sea level (MSL) continuous record, essential to understanding the climate evolution, is computed with the altimetric measurements of the TOPEX/Poseidon mission, succeeded by Jason-1 and later Jason-2.

Analyses of altimetry errors using Argo and GRACE data [PDF]
Ocean Science, 2016 This study presents the evaluation of the performances of satellite altimeter missions by comparing the altimeter sea surface heights with in situ dynamic heights derived from vertical temperature and salinity profiles measured by Argo floats.

Major improvement of altimetry sea level estimations using pressure-derived corrections based on ERA-Interim atmospheric reanalysis [PDF]
Ocean Science, 2016 The new dynamic atmospheric correction (DAC) and dry tropospheric (DT) correction derived from the ERA-Interim meteorological reanalysis have been computed for the 1992–2013 altimeter period.

Blending 2D topography images from the Surface Water and Ocean Topography (SWOT) mission into the altimeter constellation with the Level-3 multi-mission Data Unification and Altimeter Combination System (DUACS) [PDF]
Ocean ScienceThe Surface Water and Ocean Topography (SWOT) mission delivers unprecedented swath-altimetry products. Despite SWOT's 2D coverage and precision, its Level-2 ocean products suffer from the same limitations as their counterparts from nadir altimetry ...
