REPORT: U.S. Knew Of Downed Drones Vulnerabilities And Iran Says It Did Too
From EjWiki
Dozens of start-up firms are developing techniques - from deploying birds of prey to firing gas through a bazooka - to take on unmanned aerial vehicles (UAVs) that are being used to smuggle drugs, drop bombs, spy on enemy lines or buzz public spaces.
In Australia, for example, different agencies regulate drones and counter-drone technologies. "There are potential privacy issues in operating remotely piloted aircraft, but the Civil Aviation Safety Authority's role is restricted to safety. Privacy is not in our remit," the CASA told Reuters.
This is why laser jammers using industry standard laser LED diodes are effective against laser guns. The products calculate distance by measuring the time of flight of very short pulses of infrared light. This method is different from the traditional surveying instrument method of measuring phase shifts by comparing the incoming wavelength with the phase of the reflected light. Any solid object will reflect back a certain percentage of the emitted light energy - it need only be small for the sensitive detector to pick it up. The guns measure the time it takes a laser pulse to travel to the target and back with a precision, crystal-controlled time base. Knowing the speed of light, you then calculate the distance travelled. To increase accuracy, the laser measures as many as sixty pulses, utilizing a least squares method of determining the range. Sophisticated error trapping algorithms are in place to ensure a reliable reading.
The word Laser actually stands for "Light Amplification by Stimulated Emission of Radiation." It is a form of electromagnetic radiation the same as radio and microwaves. The difference is that light has a much higher frequency than radio or microwaves.
Cell phones are becoming more and more commonly found in small children's book bags now a day. Parents feel safe knowing that their children can get a hold of them at any time of day and be in constant contact with their little ones. Whether the contact be through text messaging, calling or social networking, parents like the fact that their children can get a hold of them through the use of cellular devices. The times have changed drastically, we went from not having much contact with people that are not physically around you, to having constant contact with everyone; everyone on your Facebook friends list, MySpace friends list, cell phone contact etcetera. Before it was a mere, "See you when I get home." Or, "See you after school." Now parents can call their kids at lunch, arrange meeting places, talk to the schools, their kids friends parents to arrange carpooling and so much more.
Make a research on the internet and find out the best GPS jammers available on the market. Probably one of the first results you will get is the Jammer Store Company - one of the market leaders dealing with GPS jammers. The Swedish company is known with its qualitative products for long time and this is why you can trust them. Special model of GPS jammer created by the specialists of that company can block any signal from GPS trackers within a certain area and this is their best advantage. You will be secure if you know that you have privacy due to the jammer. The other good thing here is that it will not only block GPS trackers but also any device using GPS frequencies.
One day after Iran claimed to have brought down an advanced U.S. RQ-170 Sentinel drone, Public Intelligence
received an Air Force report saying the drone suffers from many electronic vulnerabilities (via Jeffrey Carr
at Digital Dao).
The report,
Operating Next-Generation Remotely Piloted Aircraft for Irregular Warfare
was published "For Official Use Only" (FOUO) in April 2011 by the U.S. Air Force Scientific Advisory Board, and addresses electronic threats to the American drone fleet.
The light emitted by a laser is no different than any other source except that it has a unique method of generating light. The type of laser used is an infrared semiconductor laser diode. The generated light energy has a wavelength of approx. 900 nanometers, with a beam divergence of 3 millenarians, equal to a beam width of about 3 m (or ft) at 1000 m (ft). Target acquisition times range from 0.3 to 0.7 seconds.
This laser is completely eye safe, meeting FDA Class 1 specifications. This means that you could stare directly into the laser for 3 hours without any harm to your eyesight. The radiated light power on MOST lasers is in the order of 50 microwatts, or in other terms, it outputs only one twentieth the light power of a typical TV remote control, and far less than a flashlight.
If counting on the definition, the espow pocket cell phone jammer is an unique device or an instrument that is used to prevent the cell phones from receiving or sending the signals.These pocket cell phone jammers are also very useful when it comes to transmitting the signals to a base station. When a pocket cell phone jammer is used, it disables the cell phone from any further functioning and interestingly the device can be used practically at any location however the authorities usually implement it when the peace is expected.
