The algorithms presented in this book were designed to achieve an acceptable trade-off between contradictive requirements to the software of small UAV navigation systems: sufficient accuracy and reliability in order to perform required flight missions on the one hand, and acceptable cost and simplicity of this software on the other hand. The core of modern navigation systems is integrated Strapdown Inertial Navigation System (SINS) and GPS, so in this book, the SINS algorithms and the algorithms of sensor fusion are described primarily. Inertial sensors (rate gyros and accelerometers) used in SINS are manufactured on the basis of the MEMS-technology. That is why they possess poor accuracy and need to be corrected with other sensors (GPS, magnetometers, and barometric altimeters). It is necessary to take into account that flight missions of small UAVs are characterized by small flight distances, small flight times, small flight speeds, etc. These properties of small UAV flight missions and properties of MEMS-sensors create a practical background for simplification of the SINS algorithms, simultaneously preserving their accuracy at acceptable levels. The navigation algorithms for gyro-free SINS are also considered. Increasing reliability of the UAV navigation systems requires a solution of the problems of the detection of the faulty sensors. These algorithms are described. Some practical aspects of the operation of navigation systems such as initial alignment, sensors calibration, and laboratory, ground, and flight testing of integrated SINS for small UAVs are also presented.
This book will be useful for a wide circle of researchers, engineers, and graduate students involved in modern UAV design and manufacturing.

UNMANNED AIRCRAF T SYSTEMS
An unmanned aircraft system (UAS), sometimes called a drone, is an aircraft without a human pilot on board instead, the UAS can be controlled by an operator station on the ground or may be autonomous in operation. UAS are capable of addressing a broad range of applications in diverse, complex environments. Traditionally employed in mainly military applications, recent regulatory changes around the world are leading to an explosion of interest and wide-ranging new applications for UAS in civil airspace.
Covering the design, development, operation, and mission profiles of unmanned aircraft systems, this single, comprehensive volume forms a complete, stand-alone reference on the topic. The volume integrates with the online Wiley Encyclopedia of Aerospace Engineering, providing many new and updated articles for existing subscribers to that work.
The chapters cover the following items:
Airframe configurations and design (launch systems, power generation, propulsion)
Operations (missions, integration issues, and airspace access)
Coordination (multivehicle cooperation and human oversight)
With contributions from leading experts, this volume is intended to be a valuable addition, and a useful resource, for aerospace manufacturers and suppliers, governmental and industrial aerospace research establishments, airline and aviation industries, university engineering and science departments, and industry analysts, consultants, and researchers.

Описание: During World War II, Academy Award-winning director Frank Capra made propaganda films for the U.S. Government, such as Prelude to War, The Nazis Strike, The Battle of Britain, War Comes to America and The Negro Soldier. This analyses the cinematic and thematic techniques Capra employed in these films, linking them to the techniques and ideology of the director`s popular mainstream narrative films.

Описание: In this enthralling memoir we follow Max Evans and Sam Peckinpah through conversations in bars, family gatherings, binges on drugs and alcohol, struggles with film producers and executives, and Peckinpah`s abusive behavior - sometimes directed at Evans himself. Evans`s stories provide a uniquely intimate look at Peckinpah, their famous friends, and the business of Hollywood in the 1960s and 1970s.
