16-Element Anti-jamming Terminal
Product Introduction
Product Overview
The BGS-16CH-SDV-07 is a high‑performance satellite navigation anti‑jamming terminal designed for demanding industrial users. It supports anti‑suppression jamming for GPS‑L1, GAL‑E1, and BDS‑B1 frequencies, with an industry‑leading capacity to resist up to 15 simultaneous jammers per frequency point. The terminal integrates a 16‑element antenna array, advanced anti‑jamming processing, and a built‑in high‑precision receiver (ublox F9P), offering high integration, high performance, and high precision for mission‑critical applications.
Key Features

2. RNSS Signal Reception (Three Constellations)
- Receives BeiDou, GPS, and GALILEO navigation satellite signals
- Civil codes: BDS‑B1c, BDS‑B1i, GPS‑L1, GAL‑E1
3. Broad‑Spectrum Anti‑Jamming
- Suppresses narrowband, broadband, pulse, swept frequency, Gaussian, and other jamming types
- Anti‑jamming performance (J/S ratio, zero adjustment):
- Single jammer: ≥100 dB
- Seven jammers: ≥85 dB
- Fifteen jammers: ≥70 dB
4. Built‑in High‑Precision Receiver
- Default receiver: ublox F9P
- Outputs NMEA‑0183 ASCII or ublox protocol data
5. Software Upgrade
- Field upgradeable via serial port for both the anti‑jamming module and receiver module
6. System Self‑Test
- Power‑on self‑test and continuous status monitoring
7. Fire Resistance (Anti‑burn)

Installation & Use
Mounting
Install and secure using appropriate mounting hardware (customer‑provided).
Power Supply
XT30 male connector; input voltage 12–32 V DC (max 32 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 F9P 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.
