By Daniel Shepard, Jahshan A. Bhatti, and Todd E. Humphreys  Unmanned aerial vehicle (uav) used in the spoofing tests; owned by the University of Texas.  A radio signal sent from a half-mile away deceived the GPS receiver of a UAV into thinking that it was rising straight up. In this way, the UAV’s dependence on civil GPS allowed the... read more

The System: Fly the Pilotless Skies: UAS and UAV

   Unmanned aerial vehicles and civil aircraft may co-habit the airspace after September 2015.  As the U.S. Federal Aviation Administration (FAA) moves ahead with plans for unmanned aerial systems/vehicles (UAS/UAV) to have regular access to U.S. airspace by 2015, it has encountered several barriers. For UAVs to be treated like manned aircraft, their systems likley need to be qualified... read more

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

NIST and Metrology

June 11, 2012By

A few months ago at a speaking engagement, I took questions from the audience after my presentation. The audience was made up of GPS enthusiasts, GPS equipment vendors, and evidently GPS neophytes as well, because the last question was asked by a young lady, from a large well known government user segment, who was intrigued by but obviously knew little about the inner workings of GPS. Her question so stunned me and the audience that it brought the questions to an abrupt end. Thank goodness no one actually laughed out loud, and frankly I was so incredulous that I almost gave an impertinent answer that would not have served any purpose other than to embarrass the young lady and expose some insensitivity on my part. No, fortunately, after recovering from the initial shock due to the naiveté of the question, I answered her with a straight face, because it seemed to be an honest and sincere question. read more

The System: Commercial GPS in Combat

June 1, 2012By

Partnership Council Affords Insight, Drama By Alan Cameron This year’s GPS Partnership Council provided among other highlights a discussion of the tensions between commercial off-the-shelf (COTS) receiver systems used in tactical combat operations versus official military GPS user equipment (MGUE), and an enthralling warfighters’ panel that revealed much of those COTS/MGUE dilemmas. The event, held May 1–2 in El Segundo,... read more

Augmented reality delivers two important military capabilities to the warfighter: situational awareness and precision piloting capabilities, both key to survival on the battlefield. Look-ahead drive-to-position, based on accurate GPS positions, extends the importance of GPS to high-speed operation or very close maneuvering situations where humans cannot cycle through a chart or map display, then place themselves in the real world to make maneuvering decisions. read more
