Contemporary times have seen an increase in the number of navigation satellites across various geographical regions. In order to ensure that all these satellite systems work together to optimize the positioning, navigation, and timing (PNT) of users on or near the Earth’s surface there is need for inter-cooperation and inter-operability of the systems.

The 2016 Trimble Dimensions user conference and exhibition will take place at the Venetian Hotel in Las Vegas on November 7, 8 and 9.
The annual event gathers users of Trimble’s products including positioning technology for unmanned systems as well as mapping, GIS, surveying, photgrammetry and remote sensing and other technologies of interest to readers of Inside GNSS.
Four hundred and fifty technical sessions and networking events give attendees an opportunity to network widely within and among industry groups.

The USNO master clocks control GPS timing. They are accurate to within one second every 20 million years (Satellites are so picky! Humans, on the other hand, just want to know if we’re too late for lunch) USAF photo by A1C Jason Ridder.

Dr. Inder Gupta, The Ohio State UniversityChris Bartone, Ohio UniversityGNSS receivers seem to get all the attention. Go to any technical GNSS conference and the lion’s share of presentations are about receiver design and techniques: better algorithms, signal processing, integration with other sensors, spoofing detection, and on and on.

Symbols and AcronymsModernized GPS satellites give civil users the ability to achieve dual L1/L2 PY accuracy using dual L1CA/L2C ionosphere-free measurements and, with IIF satellites, dual L1/L5 signals. Because broadcast GPS ephemeris data is based on an ionosphere-free pseudorange calculated from dual L1PY/L2PY measurements and the civil signals are not all perfectly aligned to it, new broadcast parameters and a new modernized dual-frequency algorithm are needed in order to align new signals with the dual L1/L2 PY signal.

Shanghai Astronomical Observatory buildingsThe Chinese Professionals in GPS (CPGPS) sponsor their first International Conference on GNSS+ from July 27 through July 30, 2016. It will take place at the Shanghai Astronomical Observatory (SHAO) in Shanghai, China. The International Association of Geodesy (IAG) cosponsors the event.
The deadline for abstract submission has passed.
By Inside GNSSAnyone who has sat through several iterations of a slide presentation by the Federal Aviation Administration (FAA) can’t help but wonder if there isn’t a better way to do things.
As speakers flip through an exhaustively vetted series of PowerPoint slides, squeezing out a new bullet point or two from one version to the next six months later, watching paint dry seems like a more productive — and briefer — use of one’s time. The agency sometimes brings a whole new meaning to the concept of geological time.
