Book Description
On February 14, 2002, the FCC adopted a FIRST REPORT AND ORDER, released it on April 22, 2002, and on May 16, 2002 published in the Federal Register a Final Rule, permitting marketing and operation of new products incorporating UWB technology. Wireless product developers are working to rapidly bring this versatile, powerful and expectedly inexpensive technology into numerous consumer wireless devices. Past studies addressing the potential for passenger-carried portable electronic devices (PEDs) to interfere with aircraft electronic systems suggest that UWB transmitters may pose a significant threat to aircraft communication and navigation radio receivers. NASA, United Airlines and Eagles Wings Incorporated have performed preliminary testing that clearly shows the potential for handheld UWB transmitters to cause cockpit failure indications for the air traffic control radio beacon system (ATCRBS), blanking of aircraft on the traffic alert and collision avoidance system (TCAS) displays, and cause erratic motion and failure of instrument landing system (ILS) localizer and glideslope pointers on the pilot horizontal situation and attitude director displays. This report provides details of the preliminary testing and recommends further assessment of aircraft systems for susceptibility to UWB electromagnetic interference.Ely, Jay J. and Shaver, Timothy W. and Fuller, Gerald L.Langley Research CenterELECTROMAGNETIC INTERFERENCE; AIRCRAFT COMMUNICATION; COLLISION AVOIDANCE; FAILURE; RADAR BEACONS; RADIO BEACONS; AIRLINE OPERATIONS; ATTITUDE INDICATORS; CIVIL AVIATION; COMMERCIAL AIRCRAFT; INSTRUMENT LANDING SYSTEMS; RADIO RECEIVERS; WARNING SYSTEMS

Book Description
This book is an attempt to present under one cover the current state of knowledge concerning the potential lightning effects on aircraft and that means that are available to designers and operators to protect against these effects. The impetus for writing this book springs from two sources- the increased use of nonmetallic materials in the structure of aircraft and the constant trend toward using electronic equipment to handle flight-critical control and navigation function.
Radiance in Indian Skies

Book Description
The Global Geodetic Observing System (GGOS) has been established by the Int- national Association of Geodesy (IAG) in order to integrate the three fundamental areas of geodesy, so as to monitor geodetic parameters and their temporal varia- ?9 tions, in a global reference frame with a target relative accuracy of 10 or b- ter. These areas, often called ‘pillars’, deal with the determination and evolution of (a) the Earth’s geometry (topography, bathymetry, ice surface, sea level), (b) the Earth’s rotation and orientation (polar motion, rotation rate, nutation, etc. ), and (c) the Earth’s gravity eld (gravity, geoid). Therefore, Earth Observation on a global scale is at the heart of GGOS’s activities, which contributes to Global Change - search through the monitoring, as well as the modeling, of dynamic Earth processes such as, for example, mass and angular momentum exchanges, mass transport and ocean circulation, and changes in sea, land and ice surfaces. To achieve such an - bitious goal, GGOS relies on an integrated network of current and future terrestrial, airborne and satellite systems and technologies. These include: various positioning, navigation, remote sensing and dedicated gravity and altimetry satellite missions; global ground networks of VLBI, SLR, DORIS, GNSS and absolute and relative gravity stations; and airborne gravity, mapping and remote sensing systems.
B-2A Spirit Units in Combat

Pages : 223
Book Description
The B-2A 'Spirit' was an aircraft conceived to fight the Cold War but which has proved invaluable to both the 'New World Order' and more recently the 'War on Terrorism'. The combination of low-observability, precision strike, range and payload flexibility has made the 'Spirit' the weapon of choice when America hits its enemies at the start of a campaign. Spirits have fired the first shots of Operation 'Allied Force' over Kosovo and Serbia, as well as operations 'Enduring Freedom' and 'Iraqi Freedom'. Despite the tremendous cost of the aircraft – each unit is literally worth its weight in gold – the B-2 has had an impact on modern warfare which has vastly exceeded this small force of 21 bombers. Developed in utmost secrecy, the B-2's gestation saw the use of new computer design and manufacturing techniques and ultra-modern synthetic materials making it the most revolutionary aircraft in terms of design and performance. This book examines these incredible aircraft.
A Robotics Roadmap for Australia

Book Description
Australia's first Robotics Roadmap is a guide to how Australia can harness the benefits of a new robot economy. Building on Australia's strengths in robot talent and technologies in niche application areas, the roadmap acts a guide to how Australia can support a vibrant robotics industry that supports automation across all sectors of the Australian economy. The world-leading Australian Centre for Robotic Vision, an ARC Centre of Excellence, partnered with industry, researchers and government to drive this important initiative. A national consultation process was held culminating in a series of workshops across key sectors including resources, built and natural environment, manufacturing, services (including transport & logistics), healthcare and defence.Australia has a unique opportunity to take a leading role in the development of robotic technologies and in the tech sector more generally. The roadmap demonstrates Australia's existing capability and forecasts future applications, as well as providing recommendations on harnessing the new and emerging technologies being developed in Australia today. By describing what is possible and what is desirable, the roadmap aims to create the grounds for the necessary co-operation to allow robots to help unlock human potential, modernise the economy and build national health, well-being and sustainability despite the challenges of our vast and remote geography.
