A simulation tool for a laser based air traffic management system

Abstract:-Laser detection and tracking of aircrafts based systems (LIDARs, LIgth Detection And Ranging systems) are emerging as a critical design trend in development of new generation ATM (Air Traffic Management) paradigms, of which they are the main innovations. A novel laser tracking technology (SKY-Scanner System) capable to detect and track of aircrafts up to at least 6 nautical miles from the Aerodrome Traffic Zone (ATZ) has been proposed.
This paper is devoted to an experimental work conducted within the FP6 SKY-Scanner project. The aim of the project is to develop new lidar (laser radar, LIght Detection And Ranging) equipment. Radar and lidar data fusion is a requirement. One work package was devoted to decision support model design and development. The proof of the concept decision support system (DSS) being developed adopts lidar capabilities, facilitates the tasks of the ATC controller in the aerodrome traffic zone (ATZ) and contributes to aircraft surveillance. The DSS is being designed as a framework for the operational implementation of norms. Factors such as separation between aircraft, track, glide path, altitude, etc. are subject to regulation in air traffic control (ATC). Legal sources are different: the rules of the air, airport procedure charts, etc. The scientific contribution is viewed from the standpoint of computational modelling. The risk model considered is a discrete representation of a (linear) d...
ABLE: Development of an Airborne Lidar
Journal of Atmospheric and Oceanic Technology, 1999
The acronym ABLE (Airborne Lidar Experiment) identifies a project to develop and fly an optical radar on a stratospheric platform for studies related to atmospheric radiation and composition. The prototype, ABLE 1, has been successfully flown on board the M55 Geophysica aircraft in the Arctic campaign of December 1996-January 1997 to observe stratospheric clouds and aerosol. The lidar, which runs automatically, has been installed in the unpressurized bay of the aircraft where the temperature approaches the low values of external air. The lidar transmitter is based on a Nd:YAG laser, with second and third harmonic outputs. The receiver consists of a 0.3-m Cassegrain telescope and several detection channels to look at different wavelengths and polarizations. A fluid circulation unit connected to the aircraft provides heating control. The instrument can point to the zenith or to the nadir. In the past campaign only ϭ 532 nm was utilized: observations were carried out at two polarizations, pointing to the zenith. The present status of the device and foreseeable developments are described.
Laser Scanning Airborne Systems -a New Step in Engineering Surveying
The new laser scanning airborne technologies can be successfully used in engineering surveying and geodesy. They are mounted on light airplanes or on helicopters, have a fly speed comprised between 70 to 100 km/h; a height fly comprised between 50 to 100 m and can collect three-dimensional points with a density of 20 to 30 per meter. The advantages of these systems are: reduction of field work time, easy and safe access to objects (railway, roads), permit to create 3D homogeneous spatial data base, ensure the topographic and geodetic support for specific information systems.
History and Applications of Space-Borne Lidars
ISPRS - International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences
LIDAR (Light Detection and Ranging) is a laser altimeter system that determines the distance by measuring pulse travel time. The data from the LIDAR systems provide unique information on the vertical structure of land covers. Compared to ground-based and airborne LIDARs providing a high-resolution digital surface model, space-borne LIDARs can provide important information about the vertical profile of the atmosphere in a global scale. The overall objective of these satellites is to study the elevation changes and the vertical distribution of clouds and aerosols. In this paper an overview on the space-borne laser scanner satellites are accomplished and their applications are introduced.
