A study of future communications concepts and technologies for the national airspace system-Part I
The National Aviation and Space Administration (NASA) Glenn Research Center (GRC) is investigating current and anticipated wireless communications concepts and technologies that the National Airspace System (NAS) may need in the next 50 years. NASA has awarded three NASA Research Anouncements (NAR) studies with the objective to determine the most promising candidate technologies for air-to-air and air-to-ground data exchange and analyze their suitability in a post-NextGen NAS environment. This paper will present progress made in the studies and describe the communications challenges and opportunities that have been identified during the studies' first phase.
Study to identify future aeronautical communications candidates for the far-term national airspace system
A study to identify and begin to evaluate communication technology candidates expected to meet the long-term data communications needs of the post NextGen National Airspace System (NAS) was completed, considering how the NAS and communications technologies will evolve during a 50-year NAS modernization time horizon. This paper summarizes the research effort and the high level results and findings from the study. This study was completed by employees of Rockwell Collins as part of a NASA Research Announcement (NRA) agreement.
A slowly rotating coil system for AC field measurements of Fermilab Booster correctors
A method for measurement of rapidly changing magnetic fields has been developed and applied to the testing of new room temperature corrector packages designed for the Fermilab Booster Synchrotron. The method is based on fast digitization of a slowly rotating tangential coil probe, with analysis combining the measured coil voltages across a set of successive magnet current cycles. This paper presents results on the field quality measured for the normal and skew dipole, quadrupole, and sextupole elements in several of these corrector packages.
