This is the second of two lectures prepared by the authors for the von Karman Institute that deal with the subject of aerodynamic shape optimization.
The objective of this study is to develop a ow solver that can be used by aerody namic design environments to analyze a variety of candidate designs in a relatively short period of time. To meet this ...
An implicit approach to the solution of the unsteady two-dimensional Navier-Stokes equations is presented. After spatial discretization, the resulting set of coupled implicit non-linear equations is s...
An inexpensive Attitude Heading Reference System (AHRS) for General Aviation applications is developed by fusing low cost ($20 - $1000) automotive grade inertial sensors with GPS. The inertial sensor ...
There are an increasing number of applications requiring precise relative position and clock offset information.The Global Positioning System has demonstrated precise and drift free position and timin...
The Local Area Augmentation System (LAAS) is being developed by the US Federal Aviation Administration (FAA) to provide satellite navigation performance compliant with the stringent requirements for a...
The Federal Aviation Administration is leading the National Airspace System modernization e ort, in part by supplanting traditional air trac services with GPS aided by the Wide and Local Area Aug- me...
The Joint Precision Approach and Landing System (JPALS) is the next generation aircraft precision approach and landing system being sponsored by US Department of Defense. This GPS-based system will pr...
Future satellite navigation systems (like Galileo) intend to provide safety-of-life services, or at least a form of integrity information. Integrity is characterized by the Probability of Hazardously ...
Navigators have often used integration of information from multiple sensors to form a more robust and accurate navigation solution. Integrated Loran and global navigation satellite system (GNSS) is on...
Aircraft landing using the Global Positioning System (GPS) in equatorial regions is more difficult than in other regions because ionospheric scintillation is prevalent.Ionospheric scintillation causes...
Location-based security service provides authorization of persons or facilities based on their distinctive location information. It applies the field of position navigation and time (PNT) to the provi...
Deep and frequent Global Positioning System (GPS) signal fading due to strong ionospheric scintillation is a major concern for GPS-guided aviation in equatorial areas during high solar activity. A GPS...
Youth for GNSS (YGNSS) is a team created by the Space Generation Advisory Council on GNSS and the International Committee on GNSS (ICG). Composed of students and young professionals, Youth for GNSS ai...
Despite the antenna’s privileged position as the first line of defense against interferers, jammers and spoofers, most detection and mitigation techniques are realized in the receiver’s backend ...
