What's New: XAJ GNSS Anti-Jamming Receiver Module
Sep 16, 2026
Modern enterprise drones are increasingly used for aerial operations in areas with strong magnetic interference and those difficult to reach by human personnel. However, maintaining reliable positioning in these harsh environments has become a major challenge.
What new changes will the new XAJ GNSS Anti-Jamming Receiver Module, designed for the EVO Max series, bring? Let's take a look.
Which drones support the XAJ GNSS Anti-Jamming Receiver Module?
The XAJ GNSS Anti-Jamming Receiver Module is available in two models, supporting the EVO Max series and the Autel EVO III series respectively. It can help drones maintain reliable GNSS positioning in challenging radio frequency environments.
XAJ GNSS Anti-Jamming Receiver Module Specifications
The XAJ GNSS Anti-Jamming Receiver Module is a compact add-on with a plug-and-play design, allowing for easy integration without any modifications to the drone's structure.

The XAJ GNSS Anti-Jamming Receiver Module's key technologies include:
- Four-element adaptive anti-jamming antenna array
- Multi-directional interference protection
- Baseband anti-spoofing
- Real-time GNSS signal monitoring
- Real-time abnormal signal alerts
- Lightweight, low-power design
These features collectively aim to provide additional GNSS signal protection for demanding drone operations.
Do I need to install the XAJ GNSS Anti-Jamming Receiver Module?
While the EVO Max series can navigate in GPS-limited environments and is equipped with advanced flight control modules and algorithms to combat radio frequency interference (RFI), electromagnetic interference (EMI), and GPS spoofing,
it becomes insufficient for normal operations in situations with multiple interference sources, diverse interference forms, and complex electromagnetic environments, especially when facing public safety assurance, critical infrastructure inspections, and emergency rescue operations.
Enterprises and government departments should focus on the applicable scenarios and capabilities of drones when purchasing them, enhancing the GNSS positioning and flight mission support capabilities of the EVO Max series flight platform in complex electromagnetic environments.
Is the XAJ GNSS Anti-Jamming Receiver Module an original Autel Robotics product?
The XAJ GNSS Anti-Jamming Receiver Module is a third-party payload, not manufactured by Autel Robotics.
Is the XAJ GNSS Anti-Jamming Receiver Module in stock? How much does it cost?
The XAJ GNSS Anti-Jamming Receiver Module for EVO Max is expected to be available soon; the price is yet to be determined.
The XAJ GNSS Anti-Jamming Receiver Module for EVO III will be further developed after the Autel EVO III is launched; the price is yet to be determined.
