Autel SAT45 Professional UAV Antenna Transmission System — 28-Mile Smart Base Station for BVLOS Long-Range Drone Operations
UAV Antenna Transmission System Product Overview:
The Autel SAT45 UAV Antenna Transmission System is a professional-grade UAV Antenna Transmission System engineered for beyond-visual-line-of-sight (BVLOS) missions and ultra-long-range unmanned aerial operations. This intelligent smart antenna base station integrates three antennas — directional, omnidirectional, and RTK positioning — into a single lightweight, man-portable unit that delivers up to 28 miles of transmission range with 70 Mbps data throughput. Designed for seamless integration with Autel Robotics’ Dragonfish series and compatible ecosystem products, the SAT45 UAV Antenna Transmission System limited-range drone operations into true long-distance missions with enhanced wireless signal reception, superior anti-interference security, and centimeter-level positioning accuracy.
The SAT45 UAV Antenna Transmission System represents a paradigm shift in ground station architecture, consolidating multiple RF subsystems into one rapidly deployable platform. Its intelligent antenna switching algorithm continuously monitors signal quality in real-time, automatically selecting the optimal antenna configuration to maintain the strongest possible connection as the aircraft maneuvers across the operational area. This autonomous optimization eliminates manual intervention while maximizing link stability — a critical capability for professional missions where communication integrity directly impacts mission success and operational safety.
The SAT45 UAV Antenna Transmission System is the essential range-extension component for Fixed-wing Platforms conducting extended corridor inspections, Multi-rotor Drones performing large-area mapping, and any mission requiring Long Range UAV Data Link connectivity.

UAV Antenna Transmission System Advanced System Architecture
1. Triple-Antenna Intelligent Switching System
The SAT45 UAV Antenna Transmission System integrates three distinct antenna systems into a unified base station architecture. The aircraft continuously monitors signal strength with the base station in real-time, and the intelligent switching algorithm automatically transitions between antennas to maintain the strongest possible connection throughout the mission profile. When operating through the high-gain directional antenna, the system achieves the maximum 28-mile transmission range at speeds up to 70 Mbps. In MIMO configuration within 6.2 miles, the full 70 Mbps throughput is available for bandwidth-intensive applications such as 4K video streaming and high-rate telemetry. This intelligent antenna management ensures that operators always benefit from the optimal link configuration without manual intervention or technical expertise.
2. Dual-Antenna High-Precision Tracking
The SAT45 UAV Antenna Transmission System achieves highly precise antenna tracking through a dual-antenna architecture that combines the benefits of directional and omnidirectional reception. The omnidirectional antenna provides continuous signal acquisition regardless of aircraft orientation, ensuring that the tracking system never loses lock even during aggressive maneuvers or rapid heading changes. Simultaneously, the directional antenna focuses RF energy into a high-gain beam aimed precisely at the aircraft, maximizing signal strength and data throughput. This dual-antenna approach delivers the reliability of omnidirectional coverage with the performance of directional gain — a combination that is essential for maintaining stable connectivity across the full 28-mile operational envelope.
3. Centimeter-Level Positioning with Dual RTK Modules
The SAT45 features built-in dual RTK (Real-Time Kinematic) positioning modules that calculate the relative position between the base station and the aircraft with centimeter-level accuracy. By obtaining the aircraft’s precise location through the RTK correction network and combining this with the base station’s known coordinates, the system can determine the exact pointing vector required for optimal antenna alignment. This capability is particularly valuable in complex operational environments such as dense vegetation, urban canyons, and mountainous terrain where standard GPS positioning may introduce errors that degrade tracking accuracy. The centimeter-level precision ensures that the high-gain directional antenna maintains optimal alignment even when the aircraft operates at low altitudes or in GPS-challenged environments.
4. Long-Duration Dual-Battery Power System
The SAT45 is equipped with a built-in dual battery architecture capable of delivering up to 15 hours of continuous operation — sufficient for multiple sorties or extended persistent surveillance missions without recharging. The innovative 30-second quick-release battery design enables rapid field replacement, allowing operators to maintain continuous coverage through battery rotation without system shutdown. This hot-swappable power architecture eliminates operational downtime during critical missions such as emergency response, border security, and infrastructure monitoring where uninterrupted link availability is mission-critical.
5. Rapid Deployment for Mobile Operations
The SAT45 UAV Antenna Transmission System features a lightweight, man-portable design that can be quickly attached to mobile platforms including vehicles, boats, and rapid-response units near operational front lines. The quick setup and takedown capability supports highly mobile operations where the ground station must relocate frequently to maintain optimal geometry with the aircraft or to follow the progression of dynamic mission profiles. This portability transforms the SAT45 from a fixed infrastructure component into a tactical asset that adapts to evolving operational requirements — whether mounted on a survey vehicle traversing pipeline corridors, deployed on a maritime patrol vessel, or positioned at a forward observation post.
