InfiniDome proved GPS protection efficiency at the Israel-Syria border

The company has tested the GPSdome protection system during Russian jamming attack. The unprotected receiver's activity was completely disrupted, while the protected GPS receiver continued to fully function
InfiniDome Company from Caesarea, Israel, has revealed that it conducted several tests at the Israel-Syria border. The purpose of these tests was to examine the resilience level of its GPSdome, a system intended to protect GPS against jamming. The Israel-Syria border has been experiencing frequent jamming from Russian forces positioned in Syria. These forces operate powerful jamming instruments as part of their Syrian operational activities. Being highly powerful, jamming signals cross the border and interfere with IDF’s activities. In 2019, Israel publicly condemned Russian jamming attacks from Syria, which were also affecting commercial air traffic at the country’s main airport in the center of the country.
Within the test, which was conducted along the border in the Golan Heights, InfiniDome located Russian jamming attacks and analyzed their impact on the GPS navigation’s functionality. The company tested the performance of the U-Blox M8N GNSS receiver, widely used by drones and vehicles, and compared the protected GPS system’s activity with an unprotected system. The test showed that the protected receiver continued to receive GPS signals with no interruptions, even during an extremely strong jamming attack. In contrast, the unprotected GNSS receiver lost the GPS signal during the attack and the navigation system lost its orientation and positioning capabilities. At the same time, the system reported the attack via its dedicated alert output to the control room.
GPS signals are easily interrupted: The signals are incredibly weak, transmitted from satellites orbiting at 20,000 km above the Earth’s surface. The jamming can be performed in two methods: transmitting strong signals which screen the original satellite’s signals and prevent their reception, or transmitting false signals to the receiver, disrupting its positioning mechanism. The InfiniDome’s GPSdome system uses the Null Steering Algorithm technique for identification, and the company’s RFIC transmission components.
The module is capable of identifying the jamming signals as well as their originating direction, and is capable of attenuating them, thus preventing the interruption of the GNSS receiver. The module is highly adaptable, which makes it perfect for any unmanned system: it is installed between the GPS receiver and the antennas, weighs 75g and has efficient power consumption (max power consumption: <0.8W).
Strategic cooperation with Honeywell
In April 2021, InfiniDome completed a pre-series A round of $2.4 Million that includes investments from Next Gear Ventures, the lead investor, and Honeywell Ventures. Following this strategic move, both companies had conducted joint projects at the field of protecting military drones, UAV’s and flying taxis. In August 2021 they announced their first joint project: Secured navigation system for commercial and military drones. At the next phase, the companies may adjust the system for additional aerial platforms, such as UAV’s and ground vehicles.
Border lines, especially between hostile countries, are prone to GPS jamming intended to affect UAV’s expedition and lookout activities. This affects not only surveillance drones, but anyone dependent on GPS signals in the area: such as civilian drones, agricultural drones, tractors, and any other platforms using GPS, including passenger planes. For instance, along the U.S.-Mexico border, drug cartels are using jammers on U.S. border surveillance drones to hide their operations from the U.S. government, and pirates may be the cause of ship and plane navigation confusion through the use of jammers.
