Some navigation technologies other than GPS

　　Today, wireless technology has become a very important part of our lives. Mobile phones, radios, WiFi, navigators, etc. are all used in wireless technology. One of the most prominent examples of this widely used wireless technology is GPS.

　　Now that GPS is widely used, we go to an unfamiliar place. The first one is to use GPS navigation, so that we can easily find the destination, making travel route planning also become GPS navigation. There is no doubt that GPS navigation is inseparable from our lives, which is probably the main reason why GPS jammers are considered illegal.

　　However, if a tag GPS cannot be used, or the GPS is used incorrectly, such as illegal tracking. It's notoriously dangerous to put all your eggs in one basket, so there are some alternatives to GPS navigators. They are GLONASS, Cell Tower Triangulation and Wi-Fi Navigation. GLONASS is very clear to the public, like Russia's similar GPS, cell tower triangulation and Wi-Fi navigation may need explanation.

　　The first technique is cell site triangulation, which is more convenient because it uses your own cell phone to track your location. You can know that your phone is connected to at least 2-3 base stations. Their coordinates are known and fixed. Your position is calculated between three equipment towers. The advantage of this technology is that it can be used universally, because almost everyone has a cell phone that can send out a signal over a phone call, even indoors. In this case, you should use a cell phone jammer if you want to avoid tracking.

　　The second is Wi-Fi navigation. The system is under development, but the first steps will be taken by Google. Google has collected information on thousands of Wi-Fi hotspots that can be used for navigation in its Street View project. As long as the physical locations of these radio hotspots are fixed, the locations between at least three locations can be calculated. The signal strength is used to calculate the distance to each hotspot, the closer the hotspot, the stronger the signal. The future could be broad. But it also has two drawbacks: its results are inaccurate compared to GPS. And only in densely populated areas with lots of Wi-Fi hotspots. It is hoped that the accuracy of this technique will increase with

　　Here you can see some tracking technologies without a GPS signal, but that also means there are many ways to track people. In this case, if you are not sure how others are tracking you, it is recommended to use the common Gps jammer.
