{"title":"Use of eram SWIM for NAS system enhancements","authors":"Judit Klein, S. Morey","doi":"10.1109/ICNSURV.2011.5935270","DOIUrl":"https://doi.org/10.1109/ICNSURV.2011.5935270","url":null,"abstract":"The future of information management within the air traffic community is enhanced through sharing of flight data objects, enabled by the System Wide Information Management (SWIM) initiative. SWIM provides the backbone for sharing information throughout the national airspace (NAS), which allows new and existing applications and decision support tools to take advantage of current and consistent data on the SWIM infrastructure, for users to achieve common situational awareness, and systems to make optimum use of the airspace while maintaining safe operations. SWIM-enabling existing and evolving applications and decision support tools lowers the FAA's long-term maintenance costs by transitioning from point-to-point legacy interfaces to use of SWIM for information sharing. The SWIM initiative is aligned with the principles of Service-oriented architecture (SOA). En Route Automation Modernization (ERAM) is operational in Salt Lake and Seattle centers and is proceeding through site deployment for the other 18 centers. One of the significant enhancements to the baseline ERAM is the addition of the first SWIM-enabled service, the Flight Information Service (FIS). The initial version of FIS provides for processing of Traffic Flow Management System (TFMS)-initiated pre-departure re-route amendments [1]. Enhancements to the initial FIS design position it for use by other consumers for an overall life cycle cost savings. The potential uses of ERAM-provided SWIM services are numerous including modernization of existing legacy interfaces (such as Host-ATM Data Distribution System — HADDS and Flight Data Input/Output — FDIO), and the addition of new users as part of development of new applications. One potential new user, the Data Communications Air Traffic Control Facilities Notification (AFN) Accelerated Departure Clearance Service (DCL) involves several systems in achieving the end-to-end thread. FIS can accept and process updates from consumers and publish the existing ERAM flight data to authorized users, and address the specific needs of tower systems to automatically send accelerated departure clearances to aircraft. ERAM enhancements can also allow aircraft to log on as FANS aircraft, and then allow a ground station (Tower Data Link Services, TDLS) to establish controller pilot data link communication (CPDLC) sessions to exchange text from air traffic control (ATC) systems to the airplane's cockpit.","PeriodicalId":263977,"journal":{"name":"2011 Integrated Communications, Navigation, and Surveillance Conference Proceedings","volume":"21 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-05-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134192751","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

ADS-B Out periodically broadcasts information about an aircraft, such as current position, through an onboard transmitter. The FAA's final rule states that, “any ADS-B position source that meets the specified performance standards is acceptable and complies with the requirements in the final rule [1].” The position source information broadcast for ADS-B is not required to be from the sensor that is being used for navigation. It is currently required for United States Air Force (USAF) aircraft to use Precise Positioning System (PPS) Global Positioning System (GPS) for combat, combat support and combat service support operation. Standard Positioning System (SPS) is currently accepted in civil airspace worldwide for navigation; the use of PPS for navigation is accepted in the United States but not currently accepted in all countries for civil use. To satisfy both requirements, many USAF aircraft are forced to equip with both types of GPS. Providing the transponder with PPS GPS information to satisfy the current ADS-B mandate could also enable future growth to an encrypted squitter like ADS-B function that could provide aircraft location in the area of responsibility (AOR). This paper outlines the advantages and disadvantages of using a PPS sensor to satisfy the ADS-B mandate. This paper will also discuss how the use of one type of position source to satisfy the mandate could potentially benefit the USAF, specifically in the area of integration.","PeriodicalId":263977,"journal":{"name":"2011 Integrated Communications, Navigation, and Surveillance Conference Proceedings","volume":"291 2 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-05-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114384163","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

These systems are RLAN, AMT, MLS and FSS feeder links. For compatibility with the terrestrial systems, the minimum distance to interferer is calculated, i.e. the minimum distance an interfering transmitter can be from a victim receiver without degrading the system performance beyond a permitted limit. For compatibility with FSS feeder links, the number of AeroMACS systems that may be installed in Europe without causing harmful interference to non-GEO satellite feeder link receivers is calculated. The results presented in this paper indicate that both MLS and AMT may cause harmful interference to AeroMACS if no precautions are made, while this is unlikely to happen when it comes to RLANs. Concerning compatibility with FSS feeder links, more than about 400 airports in Europe must be equipped with large AeroMACS installations to potentially cause harmful interference to FSS systems.","PeriodicalId":263977,"journal":{"name":"2011 Integrated Communications, Navigation, and Surveillance Conference Proceedings","volume":"23 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-05-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117292619","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The International Telecommunication Union Radiocommunication Sector (ITU-R) has estimated in report M.2171 [1] that in the year 2030 a total of 34 MHz of spectrum will be required for terrestrial communications and another 56 MHz will be necessary for satellite communications. This paper addresses only the terrestrial (that is, direct ground/air without satellites) links. Its purpose is to validate, via a concrete example, that all of the terrestrial link requirements can be met within a potential 34 MHz allocation in portions of the L-band (960–1164 MHz) and C-band (5030–5091 MHz). There are many potentially conflicting issues that have to be addressed to satisfy the requirements levied in [1]. All of these requirements are somewhat difficult to satisfy simultaneously; however, a system design that meets the known requirements has been devised. The proposed design should be considered as an “existence proof” that the terrestrial system requirements can indeed be met; it is not necessarily the final link design.","PeriodicalId":263977,"journal":{"name":"2011 Integrated Communications, Navigation, and Surveillance Conference Proceedings","volume":"82 2 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-05-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123236498","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

These studies expect to setup a multi hop communication network among the aircrafts in the airspace. However, they have just only focused on the routing protocols which are applied for guiding the packet (aircraft position information) until the air traffic control station (ATC). This obligation prohibits any setup for direct aircraft to aircraft communication which is essential to the communication for future free flight concept. In this paper, we introduce a reliable avionic network architecture constituted not only by the aircrafts, HAPS, ATC stations. In this architecture, the aircraft position information reports will be routed to the relevant ground station by multi-hop relaying through other aircrafts or HAPS. The availability of HAPS will set up the second fixed backbone nodes in the air and aircrafts are relay nodes. In this paper, we further provide various evaluations through computer simulations firstly with CSMA/CA access scheme with the important factors such as the relay capability of the aircraft position information via system and the total accumulated delay time due to relaying processes. These evaluations are conducted in two cases of relaying network configurations. In the first case, data packets are routed through aircraft to aircraft without the availability of HAPS and the second one in which HAPS are available with a varying density. In addition, the evaluations have been conducted at different aircraft densities.","PeriodicalId":263977,"journal":{"name":"2011 Integrated Communications, Navigation, and Surveillance Conference Proceedings","volume":"22 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-05-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124977331","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this paper, a possible airborne middleware architecture in SANDRA is defined based on SWIM, aiming at the interoperation with the ground systems utilising the Service-Oriented Architecture (SOA). To define the airborne middleware architecture, the air-ground information exchange scenarios, message exchange patterns and interactions between the airborne and ground middleware are analysed. Focusing on the SWIM ATM added-value services, data access services and technical services, the air-ground service integration design are eventually defined through the identification of a set of integrated airborne/ground business processes and categories.","PeriodicalId":263977,"journal":{"name":"2011 Integrated Communications, Navigation, and Surveillance Conference Proceedings","volume":"24 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-05-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128166373","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Seeking to define a future communication system suitable for planned air-to-air and air-to-ground ATM operations, the Federal Aviation Administration (FAA) and EUROCONTROL initiated a joint study in the frame of Action Plan 17 (AP17) to investigate suitable technologies and provide recommendations to the ICAO ACP Working Group T. Two proposals for the L-band Digital Aeronautical Communication System (L-DACS) were elaborated. This paper discusses the L-DACS1 proposal, a multi-application broadband system capable of simultaneously supporting various kinds of air-to-air and air-to-ground Air Traffic Services (ATS) and Airline Operational Communications (AOC) data link services. This paper presents the research towards the design and the performance evaluation of the proposed medium access control sub-layer and logical link control sublayer of the L-DACS1 air-to-air protocol stack. The L-DACS1 air-to-air protocol has been designed for the periodic transmission of air-to-air surveillance data while supporting the transmission of a low volume of non-periodic addressed air-to-air messages. It tries to achieve this objective via a self-adaptive slotted TDMA protocol.","PeriodicalId":263977,"journal":{"name":"2011 Integrated Communications, Navigation, and Surveillance Conference Proceedings","volume":"24 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-05-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134014157","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The 5091–5150 MHz subband has also been allocated, on a co-primary basis, to mobile-satellite-service (MSS) feeder uplinks. The compatibility of ANLE networks with the MSS feeder uplinks is evaluated in this paper. An ANLE network architecture based on the Orthogonal Frequency Division Multiple Access (OFDMA) implementation described in the IEEE 802.16 family of standards is used in the analyses described below. These compatibility analyses consider interference effects from multiple ANLE base stations (BSs) at the same airport. ANLE BSs with antenna patterns having 3-dB horizontal beamwidths of 120° and 90° are analyzed. The effects of these BS antenna pattern types on the compatibility of ANLE networks with MSS feeder links are evaluated. In addition, the potential impact of downtilting the ANLE BS antennas is also addressed for both types of patterns mentioned above. Our results show that, given the parameters identified in the paper for ANLE networks and for MSS feeder uplinks, bandsharing between these systems is feasible.","PeriodicalId":263977,"journal":{"name":"2011 Integrated Communications, Navigation, and Surveillance Conference Proceedings","volume":"28 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-05-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133328185","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In a sequence of flights operated by the same tail-numbered aircraft, delays at one airport are likely to accumulate and have ripple effects on others downstream. Propagated delays are stochastic and have multiple causes. This, in turn, makes it difficult for airlines to build a reliable and robust schedule. This paper examines propagated delays in terms of a root delay in flight sequences. It compares propagated delays between hub and point-to-point airports as well as between legacy and low-cost carriers. This study shows that the point-to-point carrier under investigation propagates more delays than the legacy carrier that operates a network.","PeriodicalId":263977,"journal":{"name":"2011 Integrated Communications, Navigation, and Surveillance Conference Proceedings","volume":"2 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-05-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127994828","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
