The Ka-band propagation measurements campaign at JPL

OLYMPUS, the NASA sponsored, JPL-managed, Ka-band propagation measurement campaign carried out at Virginia Tech and many European sites, is discussed. The basic physics involved, the OLYMPUS experiment itself, and the advanced communications technology satellite (ACTS) program, the purpose of which is to demonstrate the feasibility of the Ka-band (20 and 30 GHz) spectrum for satellite communications, as well as to help maintain US leadership in satellite communications. are described. >
