CES Continues to Highlight Navigation’s Market Supremacy

January 12, 2011By

It appears that the Consumer Electronics Show is back to its pre-2009 doldrums as hotels, restaurants, cab lines, and registration numbers were up. Despite large wireless carrier presence, CES seemed to continue to be a place where aftermarket navigation providers are hawking their new units. Either way, it still is possible for LBS players, after fighting their way through miles of 3D-capable TV screens, car speakers, and dozens of entities hawking electronic tablets, to find companies still adding location to their consumer electronics offerings. read more

To Post-Process or Not to Post-Process, that Is the Question

January 5, 2011By

If you’ve been around GPS mapping for any length of time, I’m sure you’ve heard of post-processing, and you may have even experienced it yourself. If you used GPS for mapping in the '90s, you almost certainly post-processed your data. In fact, sometimes you had to pay for access to GPS base-station data for post-processing. That’s hard to imagine given the widespread, worldwide availability of GPS base-station data on the web today. read more

Expert Advice: Why Geodesy Matters, Now More than Ever

January 1, 2011By

Geodesy is a suite of powerful Earth-observation techniques, associated methodologies, and analysis tools that today are making a vital contribution to science and society. Yet geodesy is not a new, child-of-technology sciaence. It dates back hundreds of years — some would claim thousands of years, and that the ancient Greeks and other pre-Christian cultures shaped its direction. This is illustrated by its classical definition as the science of measuring and mapping the geometry, orientation in space, and gravity field of the Earth; these days we also include their variations over time. At a practical level, geodetic practice forms the foundation for surveying, navigation, and mapping, and the digital datasets underpinning these activities. read more

Death of a Smartphone, Birth of an Ad Trend

December 1, 2010By

From a distance, the Garmin-Asus partnership to produce GPS-enabled smartphones looked pretty good — particularly during the market erosion for portable navigation devices. However, published reports indicate that the companies will not renew their partnership in January 2011. Switzerland-based Garmin and its Dutch competitor TomTom have seen steeply declining sales for personal navigation devices (PNDs) since the high point of the market two years ago, industry observers say. read more

Expert Advice: The Strategic Significance of Compass

December 1, 2010By

On November 1, 2010, China’s state news agency reported that the sixth Compass satellite was launched from the Xichang Satellite Launch Center. This was the fourth Compass satellite put into orbit this year, following launches in January, June, and August. Joining the United States, Russia, and the European Union, China is deploying is own global navigation satellite system of five geosynchronous satellites, 27 in medium Earth orbit (MEO) and three in highly inclined geosynchronous orbits (IGSO). Sometimes referred to as Beidou-2, Compass is a global RNSS (radio-navigation satellite system) that broadcasts one-way precision time signals to enable receivers to calculate their position. An earlier Chinese satellite navigation system, Beidou-1, was an RDSS (radio-determination satellite system) that provided regional coverage and required two satellites to get a position fix using two-way communications with a centralized ground station. read more
