Miniature Dual Frequency GNSS BDS GPS Satellite Navigation Device Anti-Jamming Anti-Spoofing Terminal for UAV Navigation Safety for Power Timing 

The product is a miniaturized dual-protection (anti-jamming & anti-spoofing) satellite navigation integrated device designed for civilian drones and industrial users. It supports dual-frequency signal reception (BDS B1i and GPS L1) and features both anti-broadband interference (withstanding up to 3 simultaneous interference signals) and anti-spoofing capabilities.

Internally integrated with an antenna array, anti-jamming components, and a satellite navigation receiver (equipped with the ublox M10 receiver), the device delivers core functions including RNSS signal reception (compatible with BeiDou-2/3 and GPS), suppressive interference suppression, spoofing mitigation, and reliable PNT (Positioning, Navigation, Timing) information output. Key technical specifications and traits are as follows:

• Performance: Horizontal/elevation positioning accuracy ≤1.5 meters (95%), speed measurement accuracy ≤0.2 m/s (95%), timing accuracy ≤100 ns (95%);
• Power & Consumption: Input voltage 5~17V (12V recommended) via XT30 connector, power consumption ≤13W;
• Physical Size: 150 mm * 130 mm * 22 mm, weight ≤520g (color: French grey);
• Data Output: Supports NMEA string protocol or UBX protocol;
• Additional Functions: Software upgrade via serial port, system self-test, interference detection (including interference power detection), and anti-burnout protection (withstanding continuous wave power ≥10W).

• Dual-Protection Capability (Anti-Jamming + Anti-Spoofing): A key differentiator—its anti-jamming function suppresses narrowband, broadband, pulse, sweep frequency, and Gaussian suppressive interference (signal-to-interference ratio: ≥105dB for single interference, ≥95dB for three interferences); its anti-spoofing function mitigates asynchronous, synchronous, and forwarding spoofing, ensuring pure signals for backend receivers.
• High Precision & Reliability: With horizontal/elevation positioning accuracy ≤1.5 meters, speed accuracy ≤0.2 m/s, and timing accuracy ≤100 ns, it meets strict requirements for navigation and timing-critical scenarios. The built-in ublox M10 receiver further guarantees stable data output.
• Miniaturized & Lightweight Design: Measuring 150 mm * 130 mm * 22 mm and weighing ≤520g, it is compact and lightweight—ideal for space-constrained devices like drones and unmanned vehicles without adding excessive load.
• Multifunctional Integration: Combines RNSS signal reception, anti-jamming, anti-spoofing, interference detection (including interference power monitoring), system self-test, and software upgrade (via serial port for anti-jamming and receiver modules) in one unit, reducing the need for additional hardware.
• Flexible Connectivity: Offers two optional data transmission methods—TTL serial port (connects to flight controller’s GNSS serial port) and RF port (uses SMA connector, replaces conventional active antennas). Users can choose either based on application needs.
• Wide Environmental Adaptability: Operates in -40℃~+55℃ (storage: -55℃~+70℃), resists 96% relative humidity (at 40℃), and meets GJB150A rain test requirements, suitable for harsh industrial and outdoor environments.
• Robust Safety Features: Includes overvoltage protection (prevents damage from excessive input voltage) and anti-burnout protection (withstands continuous wave power ≥10W), enhancing device durability during improper operation or harsh conditions.

The device is primarily used to enhance satellite navigation security by shielding user terminals from interference and spoofing, ensuring stable PNT services. Its typical application scenarios are:

• Timing Security for Critical Sectors: Used in power grids, telecommunications networks, and financial systems to maintain interference-free and spoofing-resistant timing signals—critical for the stability of power transmission, communication signal synchronization, and financial transaction time stamping.
• Navigation Safety for Unmanned Systems: Provides reliable navigation support for drones, unmanned vehicles, and unmanned ships. It prevents navigation deviations caused by suppressive interference or spoofing attacks, ensuring safe operation during tasks like aerial surveys, autonomous driving, and maritime patrols.
• Fleet Defense Navigation: Protects vehicle fleets (e.g., military support fleets, industrial transport fleets) from navigation disruptions in complex electromagnetic environments, ensuring consistent route following and mission execution.
• High-End Logistics Navigation: Enhances the navigation accuracy and security of high-value cargo transport vehicles/equipment. It avoids delays or losses caused by navigation failures, safeguarding logistics efficiency and cargo safety.
