Abstract: Sensor calibration harmonization includes generating, over a time epoch, a time series of uncalibrated sensor measurements produced by a plurality of sensors. The time epoch is a dynamically variable span of time during which enough uncalibrated sensor measurements are collected to enable estimation of calibration gains and offsets for the plurality of sensors during the time epoch. The calibration gains and offsets are determined based on calibration harmonization of the uncalibrated sensor measurements. The calibration harmonization generates a linear transformation that determines the offsets by projecting a selected set of uncalibrated gains onto a linear subspace, and determines the calibrated gains based on the offsets. The plurality of sensors may be reconfigured in response to determining which sensors generate measurements that when calibrated based on calibration harmonization lie within an acceptable range.
