Over the last few years, a series of experiments has been carried out make geodetic measurements at K-band. The results have been encouraging, and were included as part of the ICRF3 formulation. The observations have typically been carried out using the DBBCHO and mk5ho, although the recent failure of the mark5 has forced us to include the fila10G and flexbuff instead.
