IUCAF annual report for 2021

The Scientific Committee on Frequency Allocations for Radio Astronomy and Space Science, IUCAF, was formed in 1960 by its adhering Scientific Unions, IAU, URSI, and COSPAR, at the behest of URSI. The IUCAF brief is to study and coordinate the requirements of radio-frequency spectrum allocations for passive radio sciences - radio astronomy, space research, and remote sensing - and to make these requirements known to the national and international bodies that regulate the use of the radio spectrum.
