Guarantee your drone stable positioning in any conditions. The MO-GNSSAK2 module is designed to perform reliably in areas with high RF interference. The device processes signals from all major satellite systems, providing high accuracy even with active jamming. Easy integration and low power consumption make it an ideal choice for professional UAVs.

• Full GNSS constellation and all frequencies. Support for GPS, GLONASS, BeiDou and Galileo guarantees high positioning accuracy anywhere in the world.
• Record-breaking interference suppression efficiency. The module neutralizes up to 138 dB from one interference source, providing a stable signal even in the active counteraction zone.
• Ultra-low power consumption less than 1W. The module can be powered directly from the flight controller without requiring additional power supplies.
• Protection against signal spoofing (anti-spoofing). The intelligent system detects and blocks fake GNSS signals, preventing the drone from being hijacked.
• Compact size and light weight. The module takes up only 9x9 cm and weighs less than 150 grams, without affecting the flight characteristics of your drone.

How this smart protector works and its applications

The MO-GNSSAK2 module uses a multi-element antenna array and adaptive beamforming technology. It actively analyzes the radio air, identifies sources of interference and “zeroes” them, directing the minimum signal towards the interference. The device also uses adaptive notch filtering to suppress broadband noise and analyzes baseband signals to detect fake GNSS signals (spoofing).

This ensures that your drone will always know its exact position, even in the face of aggressive electronic jamming. The module is suitable for professional UAVs in the field of geodesy, cartography, security and cargo delivery.
