Long Baseline Tightly Coupled DGNSS Positioning with Ionosphere-Free Inter-System Bias Calibration

open access: yesRemote Sensing, 2020
Based on the statistical stability of the inter-system bias (ISB), we propose a tightly coupled Differential Global Navigation Satellite System (DGNSS) positioning method by using ionosphere-free combination for the long baseline applications.

Phase and Baseline Calibration for Microwave Interferometric Radiometers Using Beacons [PDF]

open access: yesIEEE Transactions on Geoscience and Remote Sensing, 2020
The relative phase and amplitude calibration between individual receiving elements are one of the key challenges in interferometric microwave radiometry. For monolithic interferometers, for example the Microwave Imaging Radiometer with Aperture Synthesis (MIRAS) on board the Soil Moisture and Ocean Salinity (SMOS) mission, the calibration of these two ...

Optimization of Semiautomated Calibration Algorithm of Multichannel Electrotactile Feedback for Myoelectric Hand Prosthesis [PDF]

open access: yes, 2019
The main drawback of the commercially available myoelectric hand prostheses is the absence of somatosensory feedback. We recently developed a feedback interface for multiple degrees of freedom myoelectric prosthesis that allows proprioceptive and sensory

Satellite-Based Evapotranspiration in Hydrological Model Calibration

open access: yesRemote Sensing, 2020
Hydrological models are usually calibrated against observed streamflow (Qobs), which is not applicable for ungauged river basins. A few studies have exploited remotely sensed evapotranspiration (ETRS) for model calibration but their effectiveness on ...

Study on the Stability and Accuracy of Baseline Values Measured During the Calibrating Time Intervals

open access: yesData Science Journal, 2011
In order to investigate quantitatively the accuracy of geomagnetic daily variation recorded by the FGE magnetometer, we analyzed the stability and precision of some groups' baseline values continuously recorded one day at seven observatories in 2009. The
