A satellite navigation or satnav system utilizes a network of satellites to deliver autonomous geo-spatial positioning with worldwide coverage. This technology enables small electronic receivers to pinpoint their precise location (longitude, latitude, and altitude/elevation) to a high degree of accuracy, often within a few meters, by utilizing time signals transmitted via radio from the satellites. These signals also permit the receivers to calculate the current local time with remarkable precision, facilitating time synchronization. While terms „GNSS“ and „GPS“ are often used interchangeably, it’s worth noting that the Global Positioning System has likely prevented you from getting lost in an unfamiliar place. The majority of people are familiar with GPS, but the broader concept of satellite navigation encompasses more than just this one system.
High-precision satellite navigation systems, known as Global Navigation Satellite Systems (GNSS), enable small electronic receivers to ascertain their location (longitude, latitude, and altitude/elevation) using time signals transmitted by radio from satellites. These signals also facilitate the calculation of current local time with remarkable accuracy, enabling time synchronization. Operational GNSS systems include GPS, GLONASS, COMPASS, Galileo, and Beidou. Strategic GNSS jammers are designed to disable these satellite receivers, preventing the measurement of geographical coordinates. By disrupting the receiver’s ability to estimate the object’s geographical coordinates, the jammer effectively renders high-accuracy weapons less efficient, as they require precise location data to function optimally. Without this knowledge, their combat efficacy decreases significantly.
The GNSS jammer from Stratign is specially crafted to disrupt modern and upcoming satellite navigation systems, including GPS, GLONASS, COMPASS, Galileo, as well as regional systems like IRNSS (India) and QZSS (Japan). By doing so, it effectively neutralizes the targeting capabilities of winged missiles, UAVs, and gliding bombs, as these rely on precise coordinate determination for guidance. With a jamming range extending beyond 100 kilometers, Stratign’s GNSS jammers offer a powerful solution to counter enemy’s navigational advantages.

What’s the Background?
In an era where technology and electronics hold our utmost trust, we rely on them for everything from daily tasks to venturing into unknown territories. Imagine setting sail on the vast open sea or trekking deep into forests, with only electronic devices to guide your way. But what happens when these fail? This project urges you to reconsider your blind faith in electronics. Drawing inspiration from Gerardus Mercator, the great Renaissance mapmaker, we’re reminded of the importance of non-electronic冒险. Mercator, born in 1512, was not only an intellectual and mathematician but also an innovator. His Mercator projection, published in 1569, revolutionized navigation. For centuries, explorers sought a reliable way to pinpoint their globe position. Then, on June 26, 1993, a simple solution emerged. But even with such advancements, we must never forget the value of traditional methods and the dangers of over-reliance on electronics. This project aims to open your eyes to that reality.
The widespread use of GPS tracking devices has revolutionized our ability to locate and monitor positions, offering unprecedented convenience and accessibility. With the launch of the 24th satellite by the Air Force, completing the Global Positioning System (GPS) network, location-based technology has become an integral part of our daily lives. Now, with a GPS receiver costing less than a few hundred dollars, anyone can instantly determine their precise location on the planet – latitude, longitude, and even altitude – within a few hundred feet. GPS systems are now running all around us, in our cars, boats, airplanes, and many other transportation units, facilitating seamless navigation and tracking. However, this technology, like any other, has its dual use. While GPS Vehicle Tracking and Personal Monitoring Tracking can be utilized for beneficial purposes, they also have the potential for misuse. These tracker units monitor your exact location and deliver that information to a second party, raising concerns about privacy and security. Despite these challenges, the widespread availability and affordability of GPS devices have made them a popular choice for various applications, from personal safety to fleet management. Today, we are surrounded by a vast range of GPS-enabled devices, constantly evolving and expanding the possibilities of this remarkable technology.
Imagine the ease of concealing a tracker in your car, bag, or even clothes, with a device small enough to fit in your hand. Introducing our RF unit, designed to address your privacy concerns and provide ultimate discretion.

Hardware Schematics: Optimization Queries?
The core components of this project are the VCO, PIC16F870, and PLL LMX2322. A feedback loop consisting of R4 and C7 provides the PLL with RF frequency. Additionally, X1, a VCTCXO oscillator, serves as the reference frequency for both the PLL and PIC. For fine-tuning the output frequency, a pot P1 is incorporated. Notably, X1 is a highly stable and precise oscillator, and calibrating it with a frequency counter will ensure optimal performance from the jammer. However, the jammer will still function effectively even if X1 is not tuned, thanks to the precision of the VCTCXO. The PIC controls the VCO via a tuning voltage at pin 2, which is generated by the PLL filter components R6, C3, and C12. To monitor the tuning voltage, you can measure it over C3 or directly at pin 5 of the PLL. In a locked system, the voltage should range from approximately 0.5 to 1.5V. Furthermore, the PIC manages the PLL through LE, Data, and Clock inputs, setting the PLL to synchronize the VCO with the GPS frequency of 1.57542 GHz.
The core of our device lies in its hardware and schematic design. At the heart of it, pin 13 of the PIC generates the jamming signal, which is then fed to the VCO via C6. This VCO’s output directly connects to the MMIC IC3, responsible for amplifying the RF signal and transmitting it through the antenna. Powering the MMIC is a crucial aspect, managed by R3 and L1. Monitoring the current passing through R3 is essential. For ease, measure the voltage across R3 and divide it by 20. Ideally, the current should hover around 40-60 mA. Adjusting R3’s value allows you to fine-tune this current, but beware, too much current can damage the MMIC. For optimal performance, we recommend maintaining around 50 mA. Remember, higher current equates to higher gain and more output jamming power. Additionally, diode D1 serves as an indicator, confirming the PIC’s activity. It’s worth noting that the PCB’s routing and type significantly impact the system, particularly with stray inductances and capacitances. Lastly, the antenna, a whip of 45 mm, efficiently broadcasts the jamming signal.
Enhance your signal jamming capabilities with optimized hardware and schematics. Achieve superior performance and extended jamming range by upgrading to a high-gain antenna, surpassing the standard 0dB gain reference. Explore antenna options like the Homebrew GPS antenna for maximum effectiveness.
