The M-S1 is a compact GNSS signal generation module designed for drone countermeasure applications. Based on satellite signal simulation technology, it generates synthetic navigation signals across GPS, BDS, GLONASS, and Galileo bands to deceive drone positioning receivers — enabling forced landing, directional diversion, heading guidance, and no-fly enforcement. Highly integrated, low-power, and weighing just 70g, it is purpose-built for integration into handheld and miniaturized counter-UAS platforms.
