This is an ultra-small satellite navigation anti-interference integrated device designed for small and medium-sized UAVs (unmanned aerial vehicles) and industrial users. It supports anti-broadband interference and positioning functions for BDS (Beidou) B1 and GPS frequency signals, with an internal integration of an antenna array, anti-jamming components, and a satellite navigation receiver.

Key technical specifications and core functions include:

• Performance: Horizontal positioning accuracy ≤10 meters (95%), vertical positioning accuracy ≤15 meters (95%), speed measurement accuracy ≤0.2 m/s (95%), timing accuracy ≤100ns (95%);
• Power & Size: Input voltage range 5~17V (12V recommended, powered via XT30 connector), power consumption ≤6W; external dimensions 65mm*65mm*21mm, weight ≤130g (color: gray);
• Functional Traits: Receives RNSS signals from BDS-Beidou-3 and GPS (civil codes: BDS-B1C, BDS-B1I, GPS-L1); suppresses suppressive interferences (narrowband, broadband, pulse, sweep frequency, Gaussian); supports software upgrades, system self-inspection, and anti-burning protection (withstands continuous wave power ≥10W);
• Interfaces & Protocols: Equipped with J30J-9ZKP power/data interface (TTL serial ports for upgrade and anti-interference) and reserved SMA-KFD GNSS RF output port; outputs data via NMEA or ublox protocol.

• Ultra-Miniaturized & Lightweight Design: With dimensions of 65mm*65mm*21mm and weight ≤130g, it is compact and lightweight—ideal for small and medium-sized UAVs and space-constrained industrial devices, without adding excessive load.
• Low Power Consumption: Consumes only ≤6W of power, making it suitable for battery-powered equipment (e.g., UAVs) and reducing energy drain during long-term operation.
• Strong Anti-Interference Capability: Achieves a signal-to-interference ratio of ≥95dB for single interference, ≥85dB for dual interferences, and ≥80dB for triple interferences. It effectively suppresses narrowband, broadband, pulse, sweep frequency, and Gaussian suppressive interferences, ensuring stable PNT (Positioning, Navigation, Timing) services.
• Flexible Compatibility: Supports two common data protocols (NMEA and ublox), compatible with most flight controllers. It also features versatile interfaces (J30J-9ZKP for power/data, SMA for RF) to adapt to different connection needs.
• Wide Environmental Adaptability: Operates in a temperature range of -40℃~+55℃ (storage: -55℃~+70℃), resists 96% relative humidity (at 40℃), and meets GJB150A rain test requirements—reliable for harsh outdoor and industrial environments.
• Cost-Effective Replacement: Built-in locator allows it to replace conventional positioning terminals and active antennas (in RF signal access mode), simplifying system configuration and lowering overall hardware costs.
• Enhanced Safety Features: Includes anti-burning protection (withstands continuous wave power ≥10W) and system self-inspection (real-time status patrol) to prevent damage and ensure functional stability.

The product is mainly used to enhance the security and stability of satellite navigation, serving the following scenarios:

• Timing Security for Critical Sectors: Applied in power grids, telecommunications networks, and financial systems to provide interference-free timing signals. This is critical for stable power transmission, communication signal synchronization, and accurate time stamping of financial transactions.
• Navigation Safety for Unmanned Systems: Provides reliable navigation support for small and medium-sized UAVs, unmanned vehicles, 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., security patrol fleets, industrial transport 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, ensuring efficient and safe transportation by preventing interference-induced errors.

A1: It supports BDS (Beidou-3) and GPS satellite systems. The supported civil frequency bands and codes are:

• BDS-B1I (1561.098MHz, civil code: B1I);
• BDS-B1C/GPS-L1 (1575.42MHz, civil codes: B1C for BDS, L1 for GPS).

A2: Its anti-interference performance is as follows:

• Single interference: Signal-to-interference ratio ≥95dB;
• Dual interferences: Signal-to-interference ratio ≥85dB;
• Triple interferences: Signal-to-interference ratio ≥80dB.
  It can suppress multiple suppressive interferences, including narrowband interference, broadband interference, pulse interference, sweep frequency interference, and Gaussian interference.

A3: Two connection methods are available (choose one based on needs):

• Serial Port Connection: Use a DuPont line TTL serial port to connect to the flight controller’s GNSS serial port. Connect the “TX" end of the data cable to the flight controller’s “RX" interface, the “RX" end to the flight controller’s “TX" interface, and the “GND" end to the flight controller’s “GND" interface.
• RF Port Connection: Use an SMA cable to connect the product’s RF port (reserved) to the antenna port of the UAV locator.

A4: It uses an XT30 power connector, with an input voltage range of 5~17V (12V is recommended for optimal performance). Do not exceed 17V, as this may cause damage to the device.

A5: Yes, it supports software upgrades. You can upgrade the anti-interference module and receiver module via the TTL-level serial port (labeled TXD0/RXD0, designated for upgrade).

A6: It outputs data via either the NMEA protocol or ublox protocol. Before placing an order, please coordinate with the technical team to confirm the protocol matching—ensure the flight controller is set to receive one of these two protocols.

A7: Use M2 screws to install and secure the product to the platform carrier (e.g., UAV body, unmanned vehicle chassis). Ensure the installation is firm to avoid damage from vibration.

A8: The product has strong environmental adaptability:

• Operating temperature: -40℃ ~ +55℃;
• Storage temperature: -55℃ ~ +70℃;
• Relative humidity: 96% (at 40℃, non-condensing);
• Rain resistance: Complies with the requirements of the GJB150A rain test.

A9: Yes, it has anti-burning protection. It can withstand continuous wave power of ≥10W, preventing component burnout caused by strong interference.
