16-Element Dual Anti-jamming Terminal Anti-jamming Enhanced Anti-Spoofing
Product Introduction
Product Overview
The BGS-16CH-AJAS-02 is a high‑end satellite navigation anti‑jamming terminal designed for industrial users who demand the highest level of resilience. It supports BDS‑B1i and GPS‑L1 frequencies, featuring both anti‑suppression jamming (up to 15 simultaneous jammers) and enhanced anti‑spoofing capabilities. The terminal integrates a 16‑element antenna array, advanced anti‑jamming processing, anti‑spoofing modules, and a built‑in GNSS receiver (ublox M10). It protects user platforms from unintentional interference and malicious attacks, significantly enhancing PNT (Positioning, Navigation, Timing) information security for UAVs, unmanned vehicles, and other critical applications.
Key Features
1. 16‑Element Array – Resists Up to 15 Jammers
- 16‑channel anti‑jamming architecture enables suppression of up to 15 simultaneous jammers with industry‑leading jamming‑to‑signal ratios
2. RNSS Signal Reception
- Receives BeiDou and GPS navigation satellite signals
- Civil codes: BDS‑B1i, GPS‑L1
3. Broad‑Spectrum Anti‑Jamming
- Suppresses narrowband, broadband, pulse, swept frequency, Gaussian, and other jamming types on BDS‑B1 and GPS‑L1
- Anti‑jamming performance (J/S ratio, zero adjustment):
- Single jammer: ≥110 dB
- Seven jammers: ≥95 dB
- Fifteen jammers: ≥90 dB
4. Enhanced Anti‑Spoofing
- Defeats asynchronous, synchronous, and replay spoofing attacks on L1 and B1 frequencies
- Residual spoofing signal CN₀ (Carrier‑to‑Noise Ratio): ≤20 dB
- Delivers clean, authentic signals to the backend receiver
5. Built‑in High‑Performance Receiver
- Default receiver: ublox M10
- Outputs NMEA‑0183 ASCII or ublox protocol data
6. Software Upgrade
- Field upgradeable via serial port for both the anti‑jamming module and receiver module
7. System Self‑Test
- Power‑on self‑test and continuous status monitoring
8. Fire Resistance (Anti‑burn)
- Continuous wave withstand power: ≥10 W
9. Safety Protections
- Overvoltage protection and reverse connection protection

Installation & Use
Mounting
Install and secure using appropriate hardware (customer‑provided).
Power Supply
XT30 male connector; input voltage 12–34 V DC (max 34 V, 28 V recommended).
Data Connection (choose one of two modes)
Mode 1: Serial output (direct connection to flight controller)
- Use the provided data cable to connect the TTL serial port to the flight controller’s GNSS serial port:
- TX (product) → FC RX
- RX (product) → FC TX
- GND → FC GND
- Outputs NMEA‑0183 or ublox protocol positioning data.
Mode 2: RF output
- Connect the product’s RF port (SMA) to the drone’s antenna input port using an SMA cable.
- Important: The connected device must NOT supply more than 5 V to this RF port to avoid power conflicts or damage.
⚠️ When using a USB‑to‑TTL tool to connect to a computer, do not hot‑swap the USB to avoid damaging the serial port.
Flight Controller Protocol Compatibility
This product uses the ublox M10 receiver by default and can output NMEA‑0183 ASCII protocol or ublox protocol. The flight controller must be configured to receive one of these protocols. Please coordinate protocol integration with our technical team before ordering.
