The British General Lighthouse (GLA) continues to use seven new Roland electronic stations. GLA engineer Martin Bransby said that this will replace visual navigation and become a good backup for GPS. It will be put into use in mid-2014 at a cost of less than 700,000 pounds; the cost per ship for the receiver is 2,000 pounds. By 2019, the coverage will cover all major ports in the UK. The US military research organization DARPA has an experimental “single-chip timing and inertial measurement unit” (TIMU). According to project owner Andrei Shkel (Andrei Shkel), when completed, it will use small gyroscopes and accelerometers to track its position without the need for satellites or radio towers. The US “White Sands” missile system based in New Mexico is equipped with a “non-GPS-based positioning system” that uses ground antennas to provide centimeter-level positioning over 2500 square miles. In May, the Canadian government stated that it would have an impact on the cell phone jammer capabilities of military aircraft. A new type of U.S. Air Force bunker bomb designed to partially destroy Iran’s nuclear power plants includes technology that prevents defenders from blocking its satellite navigation system. MBDA is a European missile company engaged in similar work. But for many users, GPS and other space-based navigation systems (including Russia’s GLONASS, some complete Beidou projects in China and the European Union’s unfinished projects) are still essential and ubiquitous. They are also very fragile. For those whose lives or lives depend on where they are, more flexible alternatives may not be fast enough.
Also from the working principle of the WLAN jammer, you should remember that the phone jammer will broadcast the same frequency band as the phone to interfere with the normal operation of the phone, that is, our jammer is similar to our phone. Today, is there a device that can be used longer than the phone itself? Which device is more popular than mobile phones? So if we talk about the damage caused by mobile jammers-they are the same as the phone itself, then they are just Wi-Fi hotspots when the Wi-Fi signal blocks the same thing. Are these hotspots dangerous? Another thing you should know is that radio signals follow the same inverse law as light, sound waves and gravity, that is, the distance is doubled and the energy is reduced to a quarter. In other words, the longer the distance, the weaker the signal strength. The most interesting fact is that people are worried that GPS/GLONASS jamming devices are harmful, but they don’t even know that they are surrounded by signals from these positioning systems every day. Then, we want to remind you again that it is important to know which frequency you want to play. You can find any kind of information about phone blockers and other locked devices on the Internet and special websites. To be sure, this technology will not stop developing.
