Description
Space radiation sensors are normally only calibrated on ground.
Cross calibration is only applied afterwards when data sets of different sensors are compiled into one radiation model.
Both methods have their disadvantages.
Ground calibration can't reproduce space radiation spectrum and provides only a partial calibration.
Post-calibration of data sets is difficult when sensors flew on different satellites at different locations under different conditions.
In-orbit cross calibration of two (or more) space radiation sensors, on the same satellite, would provide a full comparison, at the same location & time, and under the same conditions.
The in-flight cross calibration would enhance the scientific value of the data sets of all involved sensors.
ESA's new NGRM radiation monitor will fly on the EDRS-C and MTG satellites, built by OHB.
OHB proposes to fly further radiation (and space environment) sensors for the purpose of in-orbit cross calibration.
OHB is encouraging ESA and other satellite manufactures and operators to make a joint effort to implement cross calibration in space for the benefit of the whole community.
