If you are planning on taking a road trip this summer, you are certainly not alone. According to AAA, a third of all Americans plan to take a family vacation more than fifty miles away from their home. And most of them will not be relying on their map navigational skills to get to where the need to go. Instead, a GNSS receiver will be their best friend, guiding them to their destination without having to worry about which interstate they’re on.
GPS technology is ubiquitous in our everyday lives. You probably have a GPS receiver in your smart phone or other mobile device. GPS receivers are also found in automobiles, airplanes, agricultural equipment, construction equipment, and sea vessels. A GPS antenna may be used for harsher environments and applications where precision is paramount, like those for the military. Responding to Present-Day Threats against an Aging SystemGPS was developed by the United States military back in the 1970s. It was intended for both military and civilian use with each using a different signal. There are 30 satellites in space and many ground centers in the system that allow receivers to measure time, position, and velocity. In order to determine location, a receiver needs data from four different satellites in the system. As GPS technology is used for everything from tracking a Lyft to coordinating a top-secret military mission, safeguarding against threats is a constant concern for the military and tech companies. Although the military has modernized GPS and made improvements and changes when necessary, there are many threats that could affect the accuracy and effectiveness of the system. The three most common threats are the following:
Additionally, the L.A. Times reports that the government and tech companies are developing systems and algorithms to collect data sources to determine a user’s position. These data sources, which could include TV antennas and radio stations, can provide a way to double-check the accuracy of the GPS and triangulate a location if GPS isn’t available. As we depend more on GPS technology for military and everyday applications, it’s becoming increasingly crucial that we have ways to ensure we are protected against any threats that could hinder our ability to use this technology.
