This panel examines GNSS-based systems that are designed to provide assured integrity. Assured integrity means that a system can be used in safety critical applications such as guiding aircraft to within hundreds of feet of the ground. Some of these systems are already in operation, others are nearly so. This session is intended to provide current status on each system as well future plans. The operations enabled by each system will be provided, both in the near and long term. Insight will be given on the difficulty of providing assured integrity and how these systems differ from both conventional navigational aids and conventional differential GPS. Questions from the audience are encouraged.

This session examines the role of intellectual property (IP) in the rapidly growing area of Global Navigation Satellite Systems, receiving equipment and services.

The panel will address recent changes in the interpretation of some important aspects of patent law, as well as the trends in regulation and licensing from the perspective of their impact on current and planned systems including the following:

• What are the fundamental patents that have a strong influence on GNSS systems, receiving equipment and services?
• How will the advent of multiple GNSSs, such as GPS, GLONASS, Galileo, Compass and others shape the direction of current and future IP?
• How might existing IP influence the design of emerging GNSSs?
• In what ways might the expiration of patents over the next decade affect spacecraft, receivers and services?
• What new technologies that are becoming active in the IP area may have an important effect on future systems and services?
