Precision, Navigation, and Timing (PNT) system based on Global Navigation Satellite System (GNSS) becomes significant in the air traffic management, especially in the use of Automatic Dependent Surveillance Broadcast system (ADS-B) for air traffic monitoring. Therefore the integrity of GNSS is significant to provide a reliable data necessary for ADS-B. GNSS Interference due to intentional or unintentional surrounding signal source may decrease the integrity of GNSS signal and therefore may result in the in-accurate position data of ADS-B message. ADS-B message itself is also vulnerable from potential security threats in their network. This paper proposed a methodology to detect potential security threats of ADS-B network system for both GNSS signal and ADS-B data by measuring and monitoring the electromagnetic radiated emission from ethernet cable IPv4 Cat5.

Would an increased emphasis on cost-effectiveness and markedly reduced controller workload/costs determine the Four-Dimensional Air Traffic Management (4D ATM) Concept – a mindset change? Are there workable concepts that focus on flightpath conformance monitoring rather than a combination of conformance and hazard monitoring? Fundamental criteria for a conformance management-based system are identified to meet workload and cost goals. A ‘Global Navigation Satellite System (GNSS)/Feedback Concept’ is sketched, with radical ingredients to convert GNSS's accurate position fixes into accurate aircraft flightpath navigation. This eliminates air/ground trajectory synchronisation processing, and focuses conflict probing/planning tools on non-conforming flights. This concept would need to address key Human Factor concerns satisfactorily.

Great advance is expected from the CNS/ATM (Communication, Navigation, Surveillance / Air Traffic Management) paradigm. It provides significant support of a seamless global air traffic management system. Its key technical elements are the Global Navigation Satellite System (GNSS), and the Aeronautical Telecommunication Network (ATN), which will support digital applications such as the Automatic Dependent Surveillance Broadcast (ADS-B) and the Airborne Separation Assistance System (ASAS). ADS-B will greatly increase surveillance precision and availability, and ASAS is aimed to increase traffic efficiency. This chapter provides an overview of the CNS/ATM infrastructure, the specific airborne technologies, and details of an example advanced air traffic management concept. For this example advanced concept, the chapter applies an advanced approach in dynamical safety risk modeling and Monte Carlo simulation based mid air collision risk estimation. The dynamical model covers the advanced airborne technologies and the cognitive contributions by the pilots and controllers involved. These initial results show the value of advanced airborne technologies for future air traffic management.

In Air Traffic Control (ATC), aircraft altitude data is used to keep an aircraft within a specified minimum distance vertically from other aircraft, terrain and obstacles to reduce the risk of collision. Two types of altitude data are downlinked by radar; actual flight level (Mode C) and selected altitude (Mode S). Flight level indicates pressure altitude, also known as barometric altitude used by controllers for aircraft vertical separation. ‘Selected altitude’ presents intent only, and hence cannot be used for separation purposes. The emergence of Global Navigation Satellite Systems (GNSSs) has enabled geometric altitude on board and to the controllers via the Automatic Dependent Surveillance-Broadcast (ADS-B) system. In addition, ADS-B provides quality indicator parameters for both geometric and barometric altitudes. Availability of this information will enhance Air Traffic Management (ATM) safety. For example, incidents due to Altimetry System Error (ASE) may potentially be avoided with this information. This work investigates the use and availability of these parameters and studies the characteristics of geometric and barometric data and other data that complement the use of these altitude data in the ADS-B messages. Findings show that only 8·7% of the altitude deviation is < 245 feet (which is a requirement of the International Civil Aviation Organization (ICAO) to operate in Reduced Vertical Separation Minimum (RVSM) airspace). This work provides an alert/guidance for future ground or airborne applications that may utilise geometric/barometric altitude data from ADS-B, to include safety barriers that can be found or analysed from the ADS-B messages itself to ensure ATM safety.

The threat to information security for the air navigation service providers represents a potential violation of information security of the information infrastructure elements in the air traffic management system such as communications, navigation and surveillance equipment, and the information and telecommunication systems. Typically, a threat results from the presence of vulnerable components in the protection of information technology as part of air navigation service providers activity. Generally, threats to information and communication systems include equipment failure, environmental destruction, human or machine errors, and targeted attacks, which are often complex, well-organized, and well-funded. Taking into account, information and telecommunication systems of air navigation service providers are critical resource that must be protected from external and internal threats. Information and telecommunication systems of air navigation services providers are a combination of information and telecommunication systems, in the process of processing air navigation information act as a whole. The realization of information security threats in information and telecommunication systems may adversely affect the provision of safety and air traffic management security. As a result of information security threats realization, incidents or accidents in the air traffic management system can be occurred. The paper proposes functional models of information space and information flows in the provision of air navigation service. The developed models are recommended for use in the process of security risk management in air traffic management within the new generation risk management system, as a necessary part of air navigation service provider integrated management system.

Satellite Service

The availability of an aeronautical mobile satellite service and the emergence of a global navigation satellite system should enable CNS services to be established for civil aviation, virtually worldwide. This paper discusses how the development of a low-cost ADS system, employing these satellite services, might be used to the advantage of European air traffic management (ATM). It indicates that the earlier action is taken, the greater will be the potential benefits. This paper is an updated version of that presented at the NAV94 Conference in November 1994.
