[amsat-bb] Selection of satellite (ham and non-ham) frequencies

[Joe Fitzgerald]

The ITU sets aside spectrum for ‘space science services’ which includes
both radio astronomy and scientific spacecraft operation.    The US is a
member of the ITU, and in this country licensing and frequency usage is
regulated by both the  NTIA and FCC.  In general, NASA must work with
both organizations.
