My First-Hand Experience with the Waldo Canyon Wildfire and GPS

July 10, 2012By

Tuesday, the 26th of June, started off as a beautiful day in Colorado Springs, if you ignored the towering plume of smoke to the west from the Waldo Canyon Wildfire. The wildfire started three days before in the popular Waldo Canyon hiking area in the Rocky Mountains just off Highway 24. While people in the Colorado Springs area were concerned, there were currently eight other wildfires raging in the state of Colorado and over the past month arsonist(s) were suspected of starting up to 20+ wildfires. So many had become inured to the sight and smell of smoke. Only one serious wildfire was known to be currently out of control in Colorado at the time, so concerns in the Colorado Springs community could be described as moderate. Then at 1630, that’s 4:30 P.M. for my non-military readers, the wildfire displayed its true personality. read more

A component of most GPS receiver front-ends, the automatic gain control (AGC) can flag potential jamming and spoofing attacks. The detection method is simple to implement and accessible to most GPS receivers. It may be used alone or as a complement other anti-spoofing architectures. This article presents results from a baseline AGC characterization, develos a simple spoofing detection method, and demonstrate the results of that method on receiver data gathered in the presence of a live spoofing attack. read more

On the Edge: Southwest Shakes

March 1, 2012By
Researchers used data from 25 continuous GPS stations installed as part of the EarthScope Rio Grande Rift GPS experiment, supplemented by data from other GPS monuments in the southwestern U.S., resulting in a data set of daily position estimates of 284 GPS monuments for the years 2006 through 2010.

Using a large network of GPS stations, a team of researchers has found that the Rio Valley Rift in the Southwest United States — previously suspected to be dead — is slowly expanding, at a rate of about 0.1 millimeter per year. The Rio Grande Rift extends from Colorado’s central Rocky Mountains to Mexico. read more

Out in Front: When the Gavel Comes Down

February 1, 2012By

Perhaps you don’t track suspected criminals in your spare time, nor do you design or supply a GNSS product that does so. Still, the fresh Supreme Court ruling on GPS use for this purpose reverberates for you, in ways yet unknown. The most interesting part of the court’s ruling pops up in a somewhat open-ended “what if” comment concerning future issues that at least one justice thinks the court should address. read more
