Innovation: Tsunami Detection by GPS

June 18, 2012By

How Ionospheric Observations Might Improve the Global Warning System The December 26, 2004 earthquake-generated Sumatra tsunami caused enormous losses in life and property, even in locations relatively far away from the epicentral area. The losses would likely have never been so massive had an effective worldwide tsunami warning system been in place. A tsunami travels relatively slowly and it takes... read more

Consumer GPS/GLONASS: Accuracy and Availability Trials of a One-Chip Receiver in Obstructed Environments

December 1, 2011By
figure5-opener

A one-chip multiconstellation GNSS receiver, now in volume production, has been tested in severe urban environments to demonstrate the benefits of multiconstellation operation in a consumer receiver. Bringing combined GPS/GLONASS from a few tens of thousands of surveying receivers to many millions of consumer units, starting with satnav personal navigation devices in 2011, followed by OEM car systems and mobile phones, significant shifts the marketplace. The confidence of millions of units in use and on offer should encourage manufacturers of frequency-specific components, such as antennas and SAW filters, to enter volume mode in terms of size and price. read more

GPS World took an advance look at the technology in a June trial of the demo that all ION attendees can see. This article presents these reports. read more

Product Review: The Trimble Ranger 3

August 10, 2011By

The Ranger 3 impressed me from the very first moment I saw the unit. First of all, it is designated correctly by Trimble, and the military and first responder users who wrote me, as a rugged handheld GPS-enabled computer, and it certainly fulfills all the requirements for that designation. If you are looking for a GPS device the size of an Apple iPhone, this is not the device for you. The Trimble Ranger 3 is for the user, and many of you are warfighters and first responders who need a portable and rugged but powerful handheld computer with tightly integrated GPS capabilities that can connect and communicate, wired and wirelessly, with other users and servers. The Ranger 3 can accomplish all that and much more. read more

Mobile Epiphany – Round Two

April 13, 2011By

Many of you may remember my one and only software review of a product called Touch Inspect back in December 2009, by a Denver, Colorado (Aurora)-based company called Mobile Epiphany. At the time I promised an in-depth review the software “real soon.” Well, real soon has turned into 16 months, and not a single week has gone by that I have not received several e-mails wanting to know more about the software and asking when the next review would be published. So for all of you who have been waiting, this is the promised in-depth review of Touch Inspect version 2.0, which the company now promotes as customizable software tools under the more apt heading of “Mobile Business Process Software.” But the base program is still known as Touch Inspect. read more
