How do I integrate the anti-jamming system (SGX-202 4 Frequency 8 Channel GNSS Anti-Jamming Antenna) with a UAV, such as the Matrice M400?
The SGX-202 4 Frequency 8 Channel GNSS Anti-Jamming Antenna is designed for seamless integration with UAV platforms like the Matrice M400. The integration process is straightforward and involves the following steps:
(1) Interface Connections:
The antenna uses a J30J-21 connector for power and data transmission. The key connection pins are:
Power: 12V DC (Pins 1, 2, 3 for positive, Pins 7, 8, 9 for ground).
Data Output: Serial ports (TX1, RX1, TX2, RX2) for data communication.
RF Output: The SMA-KF connector outputs the up-converted GNSS signal to the UAV’s GNSS receiver.
(2) Installation:
Mount the antenna securely on the UAV. The SGX-202 antenna is lightweight, weighing only 1200g, and is compact (160mm × 160mm × 45mm), making it ideal for integration with platforms like the Matrice M400.
Ensure the antenna is positioned to minimize signal obstructions and optimize reception in the field.
(3) Connection to Matrice M400:
Connect the RF output from the antenna to the GNSS receiver of the Matrice M400 using the SMA-KF interface for the RF signal.
Connect the serial data ports (TX/RX) to the UAV’s communication system to transmit processed positioning data.
(4)Power Supply:
Power the antenna with a 12V DC source, compatible with the M400’s power system.
(5)Configuration:
Once the hardware is installed and powered, configure the system through the UAV’s onboard software to ensure the GNSS receiver receives the interference-protected signals from the SGX-202 antenna.
This integration allows the Matrice M400 to maintain stable and reliable GNSS performance, even in challenging environments with multiple interference sources.
