GPS/GNSS Antennas (GNSS Technology and Applications)


(as of May 20,2019 23:56:03 UTC – Details)

This practical resource offers you the newest and most comprehensive treatment available of GPS/GNSS antennas, taking into account the requirements of modernized systems and recent and developing applications. The book considers a number of key applications and describes corresponding architectures and antenna details. You find important discussions on antenna characteristics, including theory of operation, gain, bandwidth, polarization, phase center, mutual coupling effects, and integration with active components.

Moreover, you get expert guidance on the design of adaptive arrays and signal processing techniques used to mitigate interference such as jamming. Addressing critical GNSS antenna high precision requirements, this in-depth book explains the relationships between antenna gain, satellite visibility, geometric dilution of precision, and the carrier-to-noise density ratio. The book delineates requirements for both dual-band and tri-band antennas.

You get detailed coverage of a wide range of antenna designs, including microstrip patch, quadrafilar helix, axial mode helix, spiral, inverted L, and planar inverted F antennas. Included is a discussion on new magnetic metamaterial substrates and other dielectric substrate materials. Further, this comprehensive book presents designs for very compact GNSS antennas for personal handheld devices and automobiles.

Contents: Introduction to GNSS Antenna Performance Parameters. Fixed Reception Pattern Antennas (FRPA) and Directional Antennas. Multiband, Handset and Active Global Navigation Satellite Systems (GNSS) Antennas. Adaptive GPS Antennas. Ground Plane, Aircraft Fuselage, and other Platform Effects on GPS Antennas. Measurement of the Characteristics of GNSS Antennas. Antennas and Site Considerations for Precise Applications.

Lost Cities author Childress takes us deep into Mexico and Central America in search of the mysterious Olmecs, North America’s early, advanced civilization. The Olmecs, now sometimes called Proto-Mayans, were not acknowledged to have existed as a civilization until an international archeological meeting in Mexico City in 1942. Now, the Olmecs are slowly being recognized as the Mother Culture of Mesoamerica, having invented writing, the ball game and the “Mayan” Calendar. But who were the Olmecs? Where did they come from? What happened to them? How sophisticated was their culture? How far back in time did it go? Why are many Olmec statues and figurines seemingly of foreign peoples such as Africans, Europeans and Chinese? Is there a link with Atlantis? In this heavily illustrated book, join Childress in search of the lost cities of the Olmecs! Chapters include: The Mystery of the Origin of the Olmecs; The Mystery of the Olmec Destruction; The Mystery of Quizuo; The Mystery of Transoceanic Trade; The Mystery of Cranial Deformation; The Mystery of Olmec Writing; more.
