Product Introduction

Product Overview

The BGS-8CH-G1-01 is a miniaturized multi‑system anti‑jamming all‑in‑one terminal, designed for industrial UAVs and other unmanned platforms that require robust navigation security. It supports GPS + GLONASS dual‑frequency signal reception and features simultaneous anti‑suppression jamming capability against up to 7 interferers – the highest channel count in the series. The device integrates an 8‑element antenna array, anti‑jamming processing module, and a full‑frequency GNSS receiver, delivering exceptional resilience with miniaturization, lightweight design, and low cost.

Key Features

1. 8‑Element Array – Resists Up to 7 Interferers

8‑channel dual‑frequency anti‑jamming architecture enables suppression of up to 7 simultaneous jammers

2. RNSS Signal Reception (Two Constellations)

Receives GPS and GLONASS navigation satellite signals
Civil codes: GPS‑L1, GLO‑G1

3. Broad‑Spectrum Anti‑Jamming

Suppresses narrowband, broadband, pulse, swept frequency, Gaussian, and other jamming types
Single jamming‑to‑signal ratio (J/S): ≥110 dB
Triple jamming ratio: ≥100 dB
Seven jamming ratio: ≥90 dB

4. Built‑in Full‑Frequency Navigation & Positioning Module

Outputs standard NMEA‑0183 or Ublox protocol data

5. Dual Output Modes (Selectable, Not Simultaneous)

Serial port output (positioning data) or RF output (cleaned anti‑jammed RF signal)
⚠️ Please specify your preferred output mode when ordering

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. Interference Detection

Real‑time interference detection and power measurement

9. Fire Resistance (Anti‑burn)

Continuous wave withstand power: ≥10 W

10. Safety Protections

Overvoltage protection and reverse connection protection

Data Connection (choose one mode – specify when ordering)

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 power to this RF port to avoid power conflicts or damage.

⚠️ When using a USB‑to‑TTL tool to connect to a computer, do not plug or unplug the USB while powered to avoid damaging the serial port.

Flight Controller Protocol Compatibility

This product outputs NMEA‑0183 or Ublox protocol. The flight controller must be configured to receive either of these protocols. Please coordinate protocol integration with our technical team before placing an order.
