Instrument details
Acronym SCS
Full name Satellite Calibration Spectrometer
Purpose To provide on-board synchronous calibration for the 8-band COCTS and the 2-band UVI instruments, to monitor the in-orbit radiation stability for COCTS and UVI.
Short description SCS can transmit 5nm bandwidth continuous spectral data in the 400~900 nm range and the in-orbit solar calibration. The bands of the HY-1 payload include 2 UV and 8 visible, near-infrared bands of UVI and COCTS.
Background Development to improve accuracy of ocean colour measurements.
