Opinions World Domination: The Sequel Published April 19, 2010 By Alan Cameron Perhaps we should call this The Interquel rather than The Sequel, as the latter will take place September 23 in Portland, Oregon, during the ION GNSS 2010 Conference. In January, 12 brave individuals joined me in San Diego to see if this thing would work at all. It did! The exercise revealed many adjustments needed […] Read more » Wide Awake blog
Survey Trimble NetR9 Reference Receiver Aimed at Infrastructure, Scientific, and Network Apps Published April 13, 2010 By GPS World Staff Join the Discussion Trimble today introduced an innovative Global Navigation Satellite System (GNSS) reference receiver for infrastructure, precise scientific, and network applications. The Trimble NetR9 GNSS reference receiver is a Continuously Operating Reference Station (CORS) receiver that can support the demanding applications for the earth science community and for the surveying, construction, mapping, and agricultural industries, Trimble said, adding that the NetR9 was designed to provide the user with maximum features and functionality from a single receiver.

Opinions Survey Solar Activity and RFID Technology Published April 7, 2010 By Eric Gakstatter Join the Discussion It’s time to touch on the solar activity subject again, as there was an event earlier this week and rumors began to fly. The mainstream press jumped on a story back in January when the first solar flare of Solar Cycle 24 occurred. Read more » RFID solar storm space weather Survey Scene
Research & Development Innovation: GPS by the Numbers Published April 1, 2010 By Richard B. Langley Join the Discussion A Sideways Look at How the Global Positioning System WorksIn his 200th Innovation column, Contributing Editor Richard Langley takes a look at GPS by the numbers, getting a sense of how GPS works by examining the key numbers that govern its remarkable capabilities, from zero to pi and beyond.

Mobile Mobile World Congress 2010: Planet of the Apps Published April 1, 2010 By GPS World Staff Join the Discussion It’s that time of year, around Valentine’s Day, when most of the who’s who in the mobile phone industry meet at the Mobile World Congress. I have been attending this event for nearly 15 years, and have seen the location change from Cannes to Barcelona, and the name change from GSM World Congress to 3GSM World Congress to Mobile World Congress. At the same time, the number of mobile phone users shot up from the millions to the billions. A new feature this year was the App Planet hall. The attendance of 47,000 was only marginally down from the 49,000 visitors in 2009, making it still a very busy a event, with no sign of the recession compared to other shows I’ve seen. It’s still the best place to meet companies in the mobile space — I met 25 in three days, as well as running into ex-colleagues and contacts who, like me, have been attending for years.

Survey Low-Frequency Vibrations Published April 1, 2010 By GPS World Staff Join the Discussion Detection with High-Rate Data and FilteringMultipath makes it difficult to detect very low-frequency structural vibrations, ranging from 0.05 to 1 Hz, important in characterizing dynamic loads and determining safe structural lifetimes. The authors have developed a phase-residual method for use with very high-frequency data to distinguish receiver noise, multipath, and the periodic displacements that are most structurally significant. The methodology can apply to bridges, tall buildings, and towers. Read more » built structures surveying
Opinions Out in Front: What’s in a Number? Published April 1, 2010 By Alan Cameron Join the Discussion Computers killed a trusty companion of my teenage years. That is, after those proto-computers known as pocket calculators knocked him out and left him unconscious on the cooling floor. But I come to praise my slide rule, not to bury him. With computers, it’s just numbers in, numbers out. Maybe that high-tech approach led both the GPS Wing and the Government Accountability Office into trouble with constellation gaps.

BeiDou Galileo GLONASS GNSS The System: Vistas from the Summit Published April 1, 2010 By Alan Cameron “This is an event where one gets one’s goals for the next year.” Paul Verhoef, program director for satellite navigation programs of the European Commission, may have exaggerated for effect, and for the benefit of his audience and hosts at the Munich Satellite Navigation Summit in March. But not by much. The conference, now in […] Read more » European Commission GPS modernization Munich Satellite Navigation Summit OEM Paul Verhoef The System
