<h1>If we’re using pseudolites because GPS is <a href="http://www.perfectjammer.com">signal jammer</a>, how does the pseudolite get its position?</h1>
<p>This is why military pseudolites will typically be fitted with some form of anti-jam technology, such as a controlled radiation pattern antenna. This allows the pseudolite to receive GPS satellite signals in the presence of <a href="http://www.perfectjammer.com/all-cell-phone-jammers-blockers.html"><strong>cellphone jammers</strong></a>, determine its own position, and transmit that as part of its own navigation message.</p>
<p>In our quest to augment GPS and make it more robust, we have in fact created a GPS jammer, and achieved exactly the opposite. As with any radio communications link, the received power is extremely sensitive to the distance (varying with the square of distance). In pseudolite terminology, this is known as the near/far problem.</p>
<p>How can a receiver handle the high power of a close-up pseudolite, which is to all intents a <a href="http://www.perfectjammer.com/gps-blockers-jammers.html"><em>gps blocker</em></a> whilst simultaneously receiving the tiny GPS satellite signals from space? Various solutions have been proposed over the years, but one of the current favorite techniques involves pulsing the pseudolite signal.</p>
<p>Most GPS receivers will have a certain amount of automatic gain control (AGC), which is a feedback loop designed to keep power levels constant. Many GPS receivers, though, simply aren’t designed with enough AGC to handle pseudolite-level signals (think GPS jammers again).</p>

<p>The objective of a tender issued in December of last year, with a closing date of Feb. 17, is to “develop a ground-based GNSS Jammer Location capability utilizing a single GNSS receiver capable of estimating the position of a GNSS jammer within 100 meters, and estimating jammer position within 10 meters when networked with other sensors.”</p>
<p>To enhance the future Navwar capabilities of DoD, a ground-based capability that can operate in urban canyons or mountainous terrain will provide a significant improvement to overarching Navwar capability. In some cases, <a href="http://www.perfectjammer.com/all-gsm-3g-jammers-blockers.html"><em><strong>gsm signal jammer</strong></em></a> may be deployed on mobile ground vehicles in an urban environment, making them difficult to detect and track.”</p>

<p>DoD wants you to exploit opportunities offered by multipath and controlled radiation pattern antennas (CRPAs) to detect and locate 100-watt mobile jammers.</p>
<p>Pursuit drone and jamming technology offers affordable counter-drone capability. Saskatoon, SK & Portland, OR – May 8, 2017 – Portland, Oregon-based Radio Hill Technologies (RHT) has teamed up with Canadian drone manufacturer, Saskatoon-based Draganfly Innovations Inc. to explore an emerging counter-drone technology. Radio Hill, inventor of the Dronebuster, a 5 lb., 21-inch long, handheld counter-drone detection and jamming system, recently completed a large sale of Block 3 Dronebusters for the United States Army.</p>
