May 31 - June 2, 2000, Cleveland, Ohio, USA
Sixth Ka-Band Utilization Conference
  Program

Program Scope

The new Millennium has brought our Conference to a new plateau, to its first meeting away from Italy to celebrate with the NASA Glenn Research Center the success of the Advanced Communications Technology Satellite (ACTS) program.

The move to Cleveland is a fitting tribute to the city that hosts the NASA Center where ACTS was conceived, managed and operated throughout its life.

The first day of the Conference will be dedicated to the ACTS Conference 2000, featuring:

• invited papers summarizing the accomplishments of ACTS from 1996 to the present
• a presentation of the Glenn Research Center's future directions in satellite communications
• a luncheon address by Dr. James Newman, one of the Shuttle astronauts that launched ACTS
• a dinner address by Mr. Joseph H. Rothenberg, NASA Associate Administrator for Space Flight
• the recognition of the industrial team that built the ACTS system
• testimonials from industry about the role of ACTS in launching Ka-band communications
• the symbolic shutdown of the ACTS payload and the conclusion of the experiments program
• a cocktail reception after dinner to permit attendees to visit, reminisce and network

The second and third days will host the Ka-band technical sessions, which this year will have to be held in parallel in order to accommodate the large number of papers submitted.
The parallel sessions will be arranged as follows:

New and Updated Systems	Propagation-Modeling and Fade Mitigation
Architectures	Propagation-Experimental Results
Ground Systems 1	Advanced in Components 1
Ground Systems 2	Advances in Components 2
Interoperability	Financing and Marketing
Protocols	Band Sharing

As in previous years, the ITALSAT Propagation Experiments Group (CEPIT), which conducts propagation studies from the ITALSAT beacons at 19, 36 and 49 GHz in five European sites, will hold its meeting on Friday morning in Humphrey Room.

The Satellite Communications in the Global Information Infrastructure (SCGII) Conference will hold its 2000 meeting in Cleveland also, joining the Ka-Band Conference.  The SCGII will hold its workshop, featuring a number of panelists from around the world, on Friday afternoon.

This is an opportunity for the Ka-Band Conference attendees to become acquainted with the work of this group that promotes the presence of high bandwidth satellites in the Global Information Infrastructure!
