The
ACTS Propagation campaign was carefully designed
to collect data in diverse climatic regions within
the ACTS coverage area using identical equipments
and software to eliminate variations in the data
collected. The program collected data for over five
years, thus providing a good indication of long-term
variations beyond the seasonal changes.
The
papers selected for this issue provide a good overview
of the propagation campaign, its implementation,
models developed, special effects observed, and
guidance for system designers on how to utilize
the data to optimize the performance of satellite
systems operating at Ka Band.
These
papers are available in portable document format
(PDF). Obtain a free copy of AdobeAcrobat
