Hardware-software complex CALIBROVKA for flight calibration of satellite survey systems
PurposeHardware-software complex KALIBROVKA is designed to be used at ground polygons for calibration of aerospace devices for remote sensing of the Earth (RSE), testing and verification of new RSE devices, mathematical planning of RSE experiments, verification and improving of reliability of RSE data decoding through integration of space, aviation and ground segments.
The novelty of the complex consists in simultaneous use of new methods of spectroscopy: integration of spectroradiometers of different spectral ranges, registration
of the images of the measured object with a spatial binding of the visual field of the spectroradiometer to the image; geographical binding of the observed objects; simultaneous imaging of the
spectra of the reflection of the underlying surface and the illuminating radiation with a high spectral resolution; possibility of measuring of the coefficients of spectral brightness and spectral
albedo; registration of spectral-angular dependence of scattered solar radiation in the atmosphere in a large number of spectral channels.

functionality due to expansion of the scientific apparatus and increased number of the spectroradiometers’ channels, presence of solar spectropolarimeter which allows measuring spectral
optical thickness of the atmosphere, possibility to work from a remote platform measuring the angles of the optical axes of the devices, use of additional nozzles increasing the number of measured
physical quantities (in particular, polarization parameters of radiation).
Application
The hardware-software complex KALIBROVKA is designed to be used at ground and aviation measurements during flight calibration of satellite survey systems and
ensuring of ground monitoring of natural and anthropogenic systems, improvement of reliability of detection and forecast of the development of dynamic processes and catastrophic events via methods of
remote sensing.
