Multi-Sensor Calibration of Low-Cost Magnetic, Angular Rate and Gravity Systems
Sensors, 2015 We present a new calibration procedure for low-cost nine degrees-of-freedom (9DOF) magnetic, angular rate and gravity (MARG) sensor systems, which relies on a calibration cube, a reference table and a body sensor network (BSN).

Reference-Free Calibration in Sensor Networks [PDF]
IEEE Sensors Letters, 2018 Sensor calibration is one of the fundamental challenges in large-scale IoT networks. In this article, we address the challenge of reference-free calibration of a densely deployed sensor network. Conventionally, to calibrate an in-place sensor network (or sensor array), a reference is arbitrarily chosen with or without prior information on sensor ...

Multisource Self-Calibration for Sensor Arrays [PDF]
IEEE Transactions on Signal Processing, 2009 Calibration of a sensor array is more involved if the antennas have direction dependent gains and multiple calibrator sources are simultaneously present. We study this case for a sensor array with arbitrary geometry but identical elements, i.e. elements with the same direction dependent gain pattern.

Characterisation methods for the hyperspectral sensor HySpex at DLR’s calibration home base
, 2012 The German Aerospace Center’s (DLR) Remote Sensing Technology Institute (IMF) operates a laboratory for the characterisation of imaging spectrometers. Originally designed as Calibration Home Base (CHB) for the imaging spectrometer APEX, the laboratory ...

FEBS Letters, EarlyView.The Ile181Asn variant of human UDP‐xylose synthase (hUXS1), associated with a short‐stature genetic syndrome, has previously been reported as inactive. Our findings demonstrate that Ile181Asn‐hUXS1 retains catalytic activity similar to the wild‐type but exhibits reduced stability, a looser oligomeric state, and an increased tendency to precipitate ...

Calibration of Kinect-type RGB-D sensors for robotic applications [PDF]
FME Transactions, 2015 The paper presents a calibration model suitable for software-based calibration of Kinect-type RGB-D sensors. Additionally, it describes a twostep calibration procedure assuming a use of only a simple checkerboard pattern.

Identifiability Analysis for Configuration Calibration in Distributed Sensor Networks
Remote Sensing, 2022 In this work, the parameter identifiability of sensor position perturbations in a distributed network is analyzed through establishing the link between rank of the Jacobian matrix and parameter identifiability under Gaussian noise.
