An increased number of positioning constellations are expected to become operational over the next decade. Consequently, each user will be able to independently conduct an integrity check for their estimated position. Through the use of a Multiple Hypothesis Solution Separation (MHSS) Receiver Autonomous Integrity Monitoring (RAIM) algorithm, it is possible to efficiently take advantage of the capabilities of future multiple-constellation Global Navigation Satellite Systems (GNSS) in order to provide error protection for the user. Additionally, large operational costs can be reduced by equipping airplanes with GNSS-enabled instrumentation. This research validates RAIM as an alternate way to bring airplanes down to a 200 ft (60 m) decision height even in poor visibility conditions and at terrain-constrained airports. The performance of the developed RAIM techniques was tested both under assumed nominal conditions and in the presence of simulated measurement faults. According to the current results, aviation users will be able to perform LPV-200 approaches at any runway worldwide based on their own integrity determination and without the need for additional augmentation systems.
This volume presents new theoretical insights, practical strategies, and policy initiatives in the rapidly evolving field of global supply chain security. As businesses, governments, and society at large have become increasingly dependent on a global network to provide goods and services, protecting global supply chains has become an issue of vital importance for industries, nations, and regions. The supply chain encompasses all the links connecting a manufacturer to end users of its products. Links may take the form of plants, supplier warehouses, vendor facilities, ports or hubs, retail warehouses or facilities, and outbound shipping centers. Links also involve all the ways goods are moved-by truck, ship, airplane, or rail car. A great deal can go wrong in the supply chain due to company or systemic mismanagement and inefficiency, criminal activity, employee or technology errors, or terrorism, to name just a few of the threats. Then there are government regulation, industry or association oversight, and security agencies (both public and private) keeping track. Globalization, stricter security regimes, and increasingly sophisticated criminal activity have made cross-border cargo movements more complex, putting the integrity of end-to-end supply chains at much greater risk. This is why the security of the supply chain has become such an important issue for business people: there is too much at stake to let problems proliferate or stagnate. It has been estimated, for example, that thieves now steal $50 billion in goods each year from various points along the supply chain. Synthesizing the most current research, practical application, and policy, Global Supply Chain Security covers a range of emerging topics-from risk assessment to technology deployment to continuity planning-and will serve as a useful resource for anyone concerned with supply chain security issues, including scholars, students, business executives and policymakers.
