Intelligent Transportation Systems (ITS) and Autonomous Vehicles make extensive use of GNSS (Global Navigation Satellite System including GLONASS/GPS/Galileo/BeiDou)technology and this dependence will only grow in the future. It’s not just that GNSS has become ubiquitous in our daily life, but many critical infrastructures worldwide have some sort of reliance on it.


GNSS plays a significant role in synchronization in the power grid, high frequency trading operations, and synchronization of distant wireless communications towers. This growing dependence on GNSS within critical (and non-critical) infrastructures has posed some concerns on the potential vulnerabilities of GNSS. As a consequence, there is a need for protecting GNSS against intentional and unintentional interference sources since disruption of GNSS can lead to catastrophic consequences.


The jamming threat, a specific form of intentional interference, is real and its occurrence has been documented in many occasions. Jamming devices are illegal in most (not all) countries, yet they are very easy and cheap to buy. Simple jammers can disrupt GNSS-based services in wide geographical areas (even in several kilometers), a fact that has certainly triggered research into anti-jamming techniques. Not only is jamming a threat, but other sources of unintentional interference can severely compromise GNSS performance.

The jamming of signals and frequencies seems so farfetched, even in today’s world, that many don’t understand the importance of this kind of technology. GNSS has become integral to the navigation and planning systems of many military and civilian devices. There exists technology today that can prevent devices from receiving GNSS signals from the satellites. In a military situation and unmanned ground vehicles or UAV, this can mean everything, as so many vehicles are equipped with GNSS devices that will not run without receiving the signal from the GLONASS/GPS/Galileo/BeiDou.

The global positioning system (GPS) was originally developed for military purposes and has proven to be essential for land, air, and sea navigation as well as for the accurate positioning for a wide range of military applications. Also, the use of anti-jamming systems and technology with GPS receivers and antennas helps prevent the jamming of signals. Therefore, the high demand for GPS and GNSS devices in military applications is driving the growth of the anti-jamming market for GPS. The ongoing developments in this technology are likely to enhance coverage and reliability. The increased penetration of the GPS technology in a wide array of applications is expected to be driven by coverage enhancements.

The development and production of anti-jamming technology is limited to a very specific, closed market sector with a particularly high cost of admission. Worldwide, only about 5-6 companies work with this technology. SMA PROGRESS,LLC GNSS Anti-Jamming Technology addresses the needs of Navigation Warfare, including Electronic Protection, Electronic Support and Electronic Attack. This GAJR equipment ensures continuous positioning even in the face of interference and jamming.


"According to the new research "Anti-Jamming Market for GPS by Receiver Type (Military & Government Grade, and Commercial Transportation Grade), Technique (Nulling, Beam Steering, and Civilian), End-User (Military, and Civilian), Application, and Geography - Global Forecast to 2023", is expected to grow from USD 3.86 billion in 2018 to USD 5.50 billion by 2023, at a CAGR of 7.34%. The growth of this market is mainly driven by factors such as the high demand for GPS technology in military applications and the ongoing developments to improve the overall GPS infrastructure".
