    This describes a NOAA-14 spacecraft loss of control event and the lessons learned. The lessons learned are in two categories: contingency recovery operations; and on-orbit propulsion system isolation methods. The work is motivated in recognition of the effort of the NOAA off-line engineering support team and their NOAA civil servant mission leads and operations support staff. View full abstract»

  • Autonomy architecture for aerobot exploration of Saturnian moon Titan

    The Huygens probe arrived at Saturn's moon, Titan, January 14,2005, unveiling a world that is radically different from any other in the solar system. The data obtained, complemented by continuing observations from the Cassini spacecraft, show methane lakes, river channels and drainage basins, sand dunes, cryovolcanos and sierras. This has led to an enormous scientific interest in a follow-up mission to Titan, using a robotic lighter-than-air vehicle (or aerobot). Aerobots have modest power requirements, can fly missions with extended durations, and have very long distance traverse capabilities. They can execute regional surveys, transport and deploy scientific instruments and in-situ laboratory facilities over vast distances, and also provide surface sampling at strategic science sites. This describes our progress in the development of the autonomy technologies that will be required for exploration of Titan. We provide an overview of the autonomy architecture and some of its key components. We also show results obtained from autonomous flight tests conducted in the Mojave Desert. View full abstract»

  • Sikkim's Teesta River fog, mist and dust particle monitoring using monostatic LiDAR

    Fog, mist, and atmospheric dust particles, having the dimension of one micrometer or less, play an important role in the deterioration of visibility, as well as in causing local warming in the atmosphere. With an attempt to reduce the deterioration, a scientific approach has to be taken to determine their origins. A monostatic LIDAR may be one of the best instruments for such work. The authors are tempted to develop such a LIDAR for fog, mist, and dust particle monitoring over River Teesta at Sikkim. LIDAR is an acronym for Light Detection And Ranging. What can we do with LIDAR? Measure distance, measure speed, measure rotation, measure chemical composition and concentration, and measure cross-sections of the targets. The digital technique is always utilized for its development which results in better security, lower power consumption, higher power efficiency, higher reliability, lower transmitter power, lower multipath effect, higher interference suppression as compared to an analog system. The commercial systems like disdometer, rain radar, mobile robot, etc., utilizing LIDAR principles are operational in different parts of the world. The authors are highly motivated for such LIDAR development and their development effort follows. View full abstract»

  • Novel radar target detection [same as "Radar target novel characteristic detection method", vol. 21, n.1, 06]

    Herein, a novel method of radar target detection based on 2-dimensional (2-D) fractal dimension is proposed. The proposed approach exploits both range information and azimuth information to estimate fractal dimension. Moreover, the approach can increase the number of data points. The above two merits result in the fractal dimension estimated by this method are more accurate and robust than the previous method. The detection performance is also better than the previous, which only makes use of 1-dimensional (1-D) information to estimate fractal dimension. Theoretical analysis and experimental results show that the proposed method performs well in a strong clutter background. The proposed method is also validated by real-life radar data, and the better result has been achieved. View full abstract»

  • Sustainable land use using consensus mapping and conflict resolution

    Land use conflicts are the typical example of spatial conflicts. They are intrinsically complex and require a comprehensive approach to their solutions. It is necessary to come to grips with the nature of their complexity to provide adequate support to deal with them. Development of land management plans through the participation of stakeholders is being appreciated and accepted as a requirement for sustainable land use. However, the involvement of stakeholders (participatory approach) gives rise to many questions. Who are the stakeholders? How to identify them? How to empower them? How to lead them through the process of negotiation? How to collate their interests to resolve the conflicts? How to facilitate this process? etc. This is an endeavour to answer the questions relevant to the support and facility that can be provided for conflict resolution by using the suitable techniques and technology. This paper introduces the concept of GIS-based collaborative decision-making and presents a general model that is developed on the basis of decision theory to support the process of conflict resolution in the context of sustainable land use.

  • Role of GIS in public health management in Pakistan

    Important objects in health databases are patients, doctors, infrastructural facilities, and health services. Nevertheless, all these objects have spatial dimensions and mutual interaction in their inheritance. The understanding of these dimensions and interactions are the key for health planning and management. For instance, these interactions may provide an excellent means of analyzing epidemiological attributes, revealing spatial trends, dependencies, and inter-relationships that would be more difficult to discover through conventional means. Moreover, it allows policy makers to easily visualize the problems in relation to the resources and prevailing needs. Spatial dimensions of health data give detailed and compelling answers to the difficult questions health service providers ask every day: Where is the disease coming from? How will it spread? Where is the nearest hospital? What is the fastest route for the ambulance? Where should we allocate our funding? In existing databases and systems of health management at public and private sectors in Pakistan, no authenticated and specific spatial reference is available. However, in a few cases, ambiguous and misleading references are there. Some isolated efforts are on the way to maintain such information as some private hospitals and companies maintain data which is commercially-available for pharmaceutical companies for marketing. The situation is getting worse due to rapidly increasing populations and thus creating further gaps in health services demand. The spatial contexts in accurate format are vital for integrating health attributes in the form of Geographical Information Systems (GIS) especially at the micro-scale. There are many potential users, but the major users will include National and Provincial health departments, Planning Commissions, researchers, etc. Undoubtedly, a health objects database could be a huge and difficult task to manage. Nonetheless, in Pakistan, precedence from National Database and Re- - gistration Authority (NADRA) is a good example of how to handle the quantity. Patients are the most dynamic health objects to deal with. It can be integrated using a NADRA identity card or similar, which contains a data strip that is readable digitally. This card may have personal information as well as the spatial origin. View full abstract»

    The editors have collected a comprehensive set of monographs that provide insight into the more recent history of bistatic radar design and implementation. This volume combines improved details of the environment along with novel system applications. Each chapter is authored by radar experts who had the vision and motivation to tackle a daunting development problem, and share their view of the successes and remaining implementation challenges. The book is divided into two parts: Bistatic/Multistatic Systems and Bistatic Clutter and Signal Processing. The book is an essential addition to the modern radar engineer's library.
