Global Navigation Satellite Systems Engineering, Policy, and Design
As ION GNSS+ 2018 approaches, we are entering the era of GNSS+ for all. All the considerations are at or very near full operational capability; dual frequency and precise spreading codes are available, free, for civilian use; raw measurements, including carrier phase, can be pulled from smartphones; and emergency services can now access the most accurate location available on your phone, indoors and out.

ION GNSS+ Program Co-Chair Jason Rife studied under one of best GNSS minds and it was his work with the late Per K. Enge that helped grow his love and understanding for position, navigation and timing (PNT). Now, at this year’s conference in Miami, his role includes helping share wisdom and knowledge for others looking to grow in this evolving industry.

Officials for the Munich Satellite Navigation Summit will be on hand at next week’s ION GNSS+ conference in Miami and will be offering specials on registration rates for their 2019 conference in the spring.
“Augment Yourself with GNSS…” will be the theme of the 2019 edition of the Munich Satellite Navigation Summit, taking place on March 25–27, 2019at the Alte Kongresshalle in Munich. The organizing Institute of Space Technology and Space Applications (ISTA) of the Universitaet der Bundeswehr Muenchen will invite experts from all over the world to talk about the latest news on Positioning, Navigation, and Timing and their role for Augmented/Mixed Reality as well as other up-to-date technologies.

The latest satellite-based augmentation system (SBAS) project update from Lockheed Martin and GMV is designed to collect data near the equatorial region and determine benefits delivered by the dual-frequency, multi-constellation SBAS.

One of the great engineering successes of the International Civil Aviation Organization (ICAO) and its expert panels is the standardization of globally harmonized Communication, Navigation and Surveillance (CNS) systems. These standards, sometimes supported by more detailed industry standards, provide safe and interoperable services between aircraft and the ground and space systems supporting them.

While threats to American defense satellites were climbing sharply, the costs and schedules of U.S. military space programs were on the same unsustainable trajectory — prompting lawmakers last year to begin trying to reorganize Air Force’s military space programs by creating a Space Corps. A move that, so far, has failed.

Rightfully, the GNSS community almost universally considers reflected signals to be problematic (the field GNSS reflectometry being an obvious exception). Reflected or non-line-of-sight (NLOS) signals combine with line-of-sight (LOS) signals to produce multipath effects, or if the LOS signal is absent NLOS signals can produce large ranging biases. Both phenomena increase measurement error and decrease positioning accuracy, especially in areas with lots of reflecting surfaces such as deep urban canyons.
