Issue 2: Propagation Campaign and Results
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.
