Product Introduction

Product Overview

The BGS-7CH-G1-01 is a miniaturized 7‑element multi‑system satellite navigation anti‑jamming integrated terminal, designed for civilian drones and industrial users requiring superior protection in dense electromagnetic environments. It supports BDS + GPS + GLONASS + GALILEO with broadband anti‑jamming capability and can withstand up to 6 simultaneous jammers – the highest in the series. The device integrates a 7‑element antenna array, high‑performance anti‑jamming processor, and a full‑constellation GNSS receiver, delivering exceptional resilience for mission‑critical applications.

Key Features

1. 7‑Element Array – Resists Up to 6 Interferers

7‑channel anti‑jamming architecture enables suppression of up to 6 simultaneous jammers

2. RNSS Signal Reception (Four Constellations)

Receives BeiDou, GPS, GLONASS, and GALILEO navigation signals
Civil codes: BDS‑B1i, BDS‑B1c, GPS‑L1, GLO‑G1, GAL‑E1

3. Broad‑Spectrum Anti‑Jamming

Suppresses narrowband, broadband, pulse, swept frequency, Gaussian, and other jamming types
Frequency support: BDS‑B1, GPS‑L1, GLO‑G1, GAL‑E1
Single interference jamming‑to‑signal ratio: ≥110 dB
Three interference ratio: ≥100 dB
Six interference ratio: ≥90 dB

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

Outputs standard NMEA‑0183 protocol data

5. Dual Output Modes

Serial port output (positioning data) or RF output (cleaned anti‑jammed RF signal)

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 (High Power Survival)

Power Supply

XT30 connector; input voltage 6–33 V DC (max 33 V).

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 → FC RX
- RX → FC TX
- GND → FC GND
Outputs NMEA‑0183 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, otherwise damage may occur.

⚠️ 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

The product outputs the NMEA 0183 standard protocol, compatible with mainstream flight controllers (e.g., Pixhawk, ArduPilot) via GNSS serial port.
