Trimble Dimensions 2016

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.

Still Not a Thing, Part 2

One of the first feature articles I wrote as a newly minted GNSS magazine editor 26 years ago was about an advanced rail traffic management system based on GPS that Burlington Northern, with the help of Rockwell Collins, had designed and implemented.

Thinking Small

Equations 2, 7, 8, 9, 10 & 11

Unmanned aerial vehicles (UAV) are finding increased application in both domestic and governmental applications. Small UAVs (maximum take off weight less than 20 kilograms) comprise the category of the smallest and lightest platforms that also fly at lower altitudes (under less than 150 meters).

Designs for this class of device have focused on creating UAVs that can operate in urban canyons or even inside buildings, fly along hallways, and carry listening and recording devices, transmitters, or miniature TV cameras.

Flying Blind

It’s 10 p.m. somewhere over the vast oceans that comprise three-quarters of the Earth’s surface. Do you know where your airplane is?

Well, you could, but maybe you don’t.

The anniversary of the disappearance of Malaysia Airlines flight MH370 came and went in March with the fate of the Boeing 777 still unknown.

It didn’t have to happen.

UN Symposium: Commercial Applications of Global Navigation Satellite Systems

Vienna, Austria

The Symposium to Strengthen the Partnership with Industry will be held on Monday, February 17, during the second week of the fifty-first session of the Scientific and Technical Subcommittee of the United Nations Committee on the Peaceful Uses of Outer Space, and will happen in parallel to the planning meeting to the Ninth Meeting of ICG and its Providers’ Forum, at the Vienna International Centre in Vienna, Austria.

Meet the New European GNSS Agency: Much the Same, Only Different

Coming nearly full circle and yet ending up in a new place with a new name describes the peculiar fortunes of the European GNSS Agency, an unlikely fate perhaps reflected most clearly in its continued use of its predecessor’s acronym, GSA.

Five years ago when Europe’s GNSS program abandoned its seemingly misconceived and now roundly condemned effort to forge a public-private partnership (PPP) to develop Galileo, the original GSA — the Galileo Supervisory Authority — appeared orphaned, bereft of purpose and patrons.

London Conference Beats Drum for Galileo Acceptance

The accompanying figure shows the acquisition results of the FM3 Galileo satellite (PRN 11) E1b data channel, as computed by the NAVigation Signal Analysis and Simulation (NavSAS) group of the Politecnico di Torino/Istituto Superiore Mario Boella (ISMB) in Italy. The upper plot shows the search space along ±7 kHz Doppler frequency, while the lower one shows the search space along 4 millisecond code delay. The coherent integration time used to obtain this search space was 4 milliseconds, coupled with 11 noncoherent accumulations.

The third Galileo in-orbit validation (IOV) satellite, also known as Flight Model 3 (FM), began transmitting signals last week, and the FM4 spacecraft, like the FM3 launched on October 12, is expected to come on-line soon — providing the theoretical capability of 3D positioning using solely satellites of Europe’s GNSS system.
