Multi-System High-Performance 7-Array Anti-Jamming Navigator Device Up to 6 Interferences Resistant SMA Port for Drone Ship Use

This product is a miniaturized 7-element multi-system satellite navigation anti-jamming integrated device designed for civilian drones and industrial users. It supports four satellite systems (BDS, GPS, GLONASS, and GALILEO) and features anti-broadband interference capability, with a maximum capacity to resist up to 6 simultaneous interference signals.

Internally integrated with a 7-element antenna array, anti-jamming components, and a satellite navigation receiver, the device combines miniaturization, lightweight design, and cost-effectiveness. Key technical specifications and functions include:

• RNSS Signal Reception: Supports civil codes of BDS-B1i, BDS-B1c, GPS-L1, GLO-G1, and GAL-E1, enabling stable reception of RNSS signals from the four satellite systems.
• Anti-Interference Function: Effective for BDS-B1, GPS-L1, GLO-G1, and GAL-E1 frequency bands, suppressing suppressive interferences such as narrowband, broadband, pulse, sweep frequency, and Gaussian interference.
• Performance Parameters: Horizontal positioning accuracy ≤1.5 meters (95%), speed measurement accuracy ≤0.2 m/s (95%), timing accuracy ≤100ns (95%); input voltage range 6~33V (powered via XT30 connector), power consumption ≤25W.
• Physical & Output Traits: External dimensions Φ220*29.5mm, weight ≤1200g (color: French grey); built-in full-frequency navigation and positioning module, outputting data via NMEA0183 protocol (optional serial port or RF port).
• Additional Functions: Software upgrade (via serial port for anti-jamming and receiver modules), system self-test, status patrol, anti-burnout protection (withstands continuous wave power ≥10W), and overvoltage protection.

• Multi-System Compatibility: Supports BDS, GPS, GLONASS, and GALILEO simultaneously, avoiding reliance on a single satellite system. This enhances signal reception stability and redundancy in complex electromagnetic environments.
• Superior Anti-Interference Performance: Achieves a signal-to-interference ratio of ≥110dB for single interference, ≥100dB for three interferences, and ≥90dB for six interferences—effectively suppressing multiple types of suppressive interference and ensuring uninterrupted PNT (Positioning, Navigation, Timing) services.
• Miniaturized & Lightweight Design: With dimensions of Φ220*29.5mm and weight ≤1200g, it is compact and lightweight, suitable for space-constrained applications (e.g., civilian drones, unmanned vehicles) without adding excessive load.
• Flexible Data Output: Offers two optional output methods—TTL serial port (connects to flight controller’s GNSS serial port via DuPont line) and RF port (connects to drone locator’s antenna port via SMA cable)—adapting to diverse device connection needs.
• Robust Safety & Durability: Equipped with overvoltage protection (prevents damage from abnormal input voltage) and anti-burnout protection (withstands continuous wave power ≥10W). It also meets GJB150A rain test requirements, ensuring reliability in harsh conditions.
• Wide Voltage Adaptability: Supports an input voltage range of 6~33V, compatible with various power supplies in industrial and unmanned scenarios, reducing power matching constraints.
• Low Cost & High Integration: Integrates antenna array, anti-jamming components, and navigation receiver into one unit, replacing conventional positioning terminals and active antennas—simplifying system configuration and lowering overall costs.

The device is mainly used to enhance the security and stability of satellite navigation systems, protecting user terminals from interference. Its typical application scenarios include:

• Time Synchronization Security: Applied in power grids, telecommunications networks, and financial systems to provide interference-free timing signals—critical for the stability of power transmission, communication signal synchronization, and financial transaction time stamping.
• Navigation for Unmanned Systems: Provides reliable navigation support for civilian drones, unmanned cars, and unmanned ships. It prevents navigation deviations caused by interference, ensuring safe operation during tasks like aerial surveys, autonomous driving, and maritime patrols.
• Fleet Defense Navigation: Used in vehicle fleets (e.g., industrial transport fleets, security patrol fleets) to maintain stable navigation in complex electromagnetic environments, avoiding mission disruptions due to navigation failures.
• High-End Logistics Navigation: Enhances the navigation accuracy and anti-interference capability of high-value cargo transport vehicles/equipment. It ensures the efficiency and safety of cargo transportation by preventing interference-induced navigation errors.

A1: It supports four satellite systems: BDS (BeiDou), GPS, GLONASS, and GALILEO. The supported civil frequency bands (civil codes) are BDS-B1i, BDS-B1c, GPS-L1, GLO-G1, and GAL-E1. The corresponding operating frequencies are: BDS-B1 (1561.098MHz), GPS-L1/GAL-E1 (1575.42MHz), and GLO-G1 (1602MHz).
