Opinions Survey ION GNSS Conference Peers into the Future of Surveying Published September 1, 2009 By Eric Gakstatter Join the Discussion The Institute of Navigation’s Global Navigation Satellite Systems (ION GNSS) conference is one of my two favorite industry events of the year; the other being the ESRI conference. At ESRI, I mix it up with GPS technology users, listen to what they are doing and what they want to do with the technology. At ION, I listen to GNSS designers and researchers.

GNSS Research & Development Innovation: One Year in Orbit Published September 1, 2009 By Richard B. Langley GIOVE-B E1 CBOC Signal Quality AssessmentGIOVE-B has been in orbit for just over one year. How well is it performing? In particular, what can we say about one of GIOVE-B's pioneering features: its E1 CBOC signal? In this month's column, we take a detailed look at a particular monitoring and assessment program set up to examine the GIOVE-B signals and discuss some of its initial CBOC results. The successful operation of this program bodes well for its use in future validation campaigns. Read more » Galileo IOV GIOVE-B In-Orbit Validation Weilheim Measurement Wolfgang Kogler
Real-Time Software Receivers: Challenges, Status, Perspectives Published September 1, 2009 By GPS World Staff By Marcel Baracchi-Frei, Grégoire Waelchli, Cyril Botteron, and Pierre-André Farine The idea of a software receiver is to replace the data processing implemented in hardware with software and to sample the analog input signal as close as possible to the antenna. Thus, the hardware is reduced to the minimum — antenna and analog-to-digital converters (ADCs) […] Read more » GNSS software receiver OEM receiver design software receiver
Opinions Letters to the Editor Published August 27, 2009 By GPS World Staff Join the Discussion Reaction to August’s editorial, “Fair Play to Those Who Dream,” concerning the as-yet unreleased Galileo signal specification, came swift — and mixed — from both sides of the Atlantic.

Opinions Survey ESRI Conference and SVN-49 Troubles Published July 29, 2009 By Eric Gakstatter Join the Discussion I had a great visit at the ESRI User Conference earlier this month. If you recall last year, I wrote: “As much as surveyors, engineers, and constructors may not appreciate geographic information systems (GIS) technology, at some point everyone should attend at least the ESRI Survey/Engineering Summit and the first couple of days of the ESRI User Conference held every summer in San Diego, California. This is not a GIS sales pitch. It's a networking sales pitch. When other conferences are struggling to maintain attendance levels, the ESRI conferences seemingly never fail to grow in attendance. This year, it attracted some 15,000 people from 120 countries. That means gobs of GIS people, and also gobs of surveyors and engineers.” The statement rang true this year too. Even in today’s economy where conferences are severely impacted or even cancelled due to travel budget cuts, the ESRI User conference still attracted ~11,000 people this month.
