CubeSat mm-wave calibration loads ship to NASA Goddard

At the end of January, TK shipped two types of loads for mm-wave radiometer calibration:  An internal cone load
- derived from the SWI instrument on ESA's Juice mission. In this case TK is a subcontractor to VDI, having also
designed and buit the from end optics of the protype CubeSat

.. and two loads derived from the warm pyramidal target on the MetOP-SG Ice Cloud Imager mission:

The latter can be seen in our TVAC chamber where the embeded Platinum Resistance Thermometers (PRTS)
are being calibrate against four surounding SPRTs, to a precision at the 10mK level.
