The objective of ACTS was to prove that a Ka Band system with onboard switching could reliably provide digital integrated services for all types of applications and data rates, and operate seamlessly with terrestrial networks.

The ACTS Experiment Program was established to work with industry, academia and government to carry out the demonstrations and communications experiments needed to verify the ACTS objective. Many people were involved in this program and a large number of papers were published to document the results.

The papers selected for this issue highlight significant experiments showing that switched Ka Band systems provide reliable service with effective rain fade compensation, that TCP/IP protocol is suitable for geo satellites, that satellites are ideally suited for broadband service to mobile and remote environments as well as for terrestrial applications.

These papers are available in portable document format (PDF). Obtain a free copy of AdobeAcrobat Reader to view PDF files.
