CES Continues to Highlight Navigation’s Market Supremacy

January 12, 2011 - By

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, 2011 - By

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, 2011 - By

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

Innovation: The Distress Alerting Satellite System

January 1, 2011 - By

Taking the Search out of Search and Rescue
In 1997, a Canadian government study determined that an improved search and rescue system would be one based on medium-Earth orbit satellites, which can provide full global coverage, can determine beacon location, and would need fewer ground stations. This month’s column examines the architecture of the GPS-based Distress Alerting Satellite System and takes a look at early test results. read more

Qualitative Motion Analysis: INS/GNSS in Care-Giving Applications

January 1, 2011 - By

A pocket tracker for elderly people and Alzheimer’s patients consists of a smartphone using GNSS, WLAN, RFID, and GSM for basic positioning, communication channels, and an accelerometer triad for collapse and motion detection. It seeks to determine not only the quantitative where but the qualitative how: has the user lost balance, fallen, or ceased moving? read more
