Implementation and performance evaluation of an inertial navigation system/global navigation satellite system real‐time kinematic Ntrip navigation system aided by a robot operating system‐based emulated odometer for high‐accuracy land vehicle navigation in urban environments

Engineering Reports, 2020
Advanced land‐vehicle navigation commonly uses integrated systems to counteract global navigation satellite system (GNSS) solution degradation. This occurs mainly in urban environments due to blockage of the satellite signals.

Spatial pattern consistency and repeatability of proximal soil sensor data for digital soil mapping

European Journal of Soil Science, Volume 74, Issue 5, September–October 2023., 2023
Abstract Data from proximal soil sensors can facilitate digital soil mapping at high spatial resolutions. However, their use for predicting static soil properties, such as texture, is affected by spatio‐temporal changes in environmental and measurement conditions.

Rethinking the regularity in mobility patterns of personal vehicle drivers: A multi‐city comparison using a feature engineering approach

Transactions in GIS, Volume 27, Issue 3, Page 663-685, May 2023., 2023
Abstract Large‐scale trajectory data offer a finer lens into the regularity in individual mobility choices. Previous studies have exerted efforts to measure the regularity in people's location visiting patterns. However, the complexity of travel behavior at different spatial and temporal scales has not been adequately considered.

A‐CHAIM: Near‐Real‐Time Data Assimilation of the High Latitude Ionosphere With a Particle Filter

Space Weather, Volume 21, Issue 3, March 2023., 2023
Abstract The Assimilative Canadian High Arctic Ionospheric Model (A‐CHAIM) is an operational ionospheric data assimilation model that provides a 3D representation of the high latitude ionosphere in Near‐Real‐Time (NRT). A‐CHAIM uses low‐latency observations of slant Total Electron Content (sTEC) from ground‐based Global Navigation Satellite System ...
