In scientific research exploration, emergency rescue operations, and specialized communication support scenarios, continuous and stable communication relay capability is the core and critical factor for mission execution. The most significant limitation of conventional UAV relays lies in their restricted flight endurance; with an operational duration of only a few dozen minutes, they can only perform brief signal fill-in operations, failing to meet the requirements for long-duration, all-weather, uninterrupted high-altitude network deployment, thereby severely limiting operational efficiency and the effectiveness of mission implementation.

    To truly achieve routine high-altitude communication, the key does not lie in flying high, but rather in “staying airborne for an extended period, maintaining stable connectivity, and ensuring uninterrupted communication.”

Weize has been dedicated to the field of tethered aerial communications for eight years, focusing on addressing industry pain points such as short flight ranges, unstable signal transmission, and low safety levels in aerial continuous communication scenarios. As part of this major upgrade, Weize has completed the customized tethered relay modification for the DJI FC100 drone, centering its efforts on achieving long-duration flight endurance and uninterrupted relay capabilities to deliver a high-stability all-weather, round-the-clock high-altitude communication relay solution.

📡 The core value of tethered relay: Addressing the industry’s most significant pain point – limited battery life.

Traditional UAV relays rely on onboard batteries for power supply, offering a flight duration of only a few dozen minutes, which makes them inadequate for continuous surveillance operations. In contrast, the Weize tethered relay system leverages its advantage of wired continuous power supply to completely revolutionize traditional operation paradigms; its core strengths lie in long-duration endurance and sustained relay capabilities, enabling precise adaptation to three critical operational scenarios:

Scientific research and experimental scenarios: Supports all-weather, multi-time-period continuous operation, enables long-duration stable relay transmission of data, and meets the persistent communication requirements for various long-distance scientific surveys and low-altitude experiments.

Military special operations scenarios: enabling 24/7 fixed-point airborne relay services, establishing long-term and stable high-altitude communication links, overcoming the limitations of ground-based communications, and ensuring uninterrupted communication throughout the entire duration of special missions.

Emergency rescue scenario: Following damage to ground-based communication facilities caused by a disaster, the aircraft can rapidly take off and remain airborne for an extended period to restore network connectivity, thereby continuously maintaining communication channels for rescue command, video transmission, and personnel-to-person two-way communication.

Over eight years of dedicated expertise in the fixed-wing relay domain, we have accumulated a vast repository of long-duration airborne and field-based network deployment test cases; all battery endurance and relay performance metrics are verified by real-world footage, ensuring our solutions are mature, stable in performance, and fully capable of withstanding rigorous practical testing.

✨ Synergistic Enabling: The FC100 platform maximizes the release of Zhongjixuhang’s competitive advantages

The core logic of this solution is as follows: centered around fixed-wing long-duration continuous flight technology and utilizing the DJI FC100 heavy-lift drone as a premium carrier, it leverages the platform’s exceptional stability and high payload capacity to fully enable uninterrupted relay capabilities and address all limitations inherent in traditional relay systems:

Core Breakthrough | Infinite Range Relay: By abandoning traditional battery-powered configurations and leveraging a tethered wired continuous power supply system, this solution enables 24-hour uninterrupted high-altitude relay monitoring, thereby addressing the range limitation challenge at its root.

Capability Upgrade | All-encompassing stable networking: ensures stable high-altitude hovering posture, avoids terrain obstructions, significantly expands relay signal coverage range, and guarantees continuous, uninterrupted signal throughout the entire transmission path.

Maximized Performance | High-Power Continuous Relay: The FC100 offers ample payload margin, enabling the deployment of high-power relay equipment, supporting simultaneous access for multiple terminals, and providing long-term, stable support for large-scale network deployment tasks.

All-weather operation | Continuous monitoring in complex environments: The platform features strong wind and interference resistance; when paired with a proven tethered system, it can maintain stable mid-flight performance and reliable signal transmission even in harsh environmental conditions.

💡 Three major customized modifications – strengthening long-duration continuous flight capability and ensuring a robust safety barrier.

All modifications and optimizations are centered around the core design objectives of “extending flight range, ensuring stable relay operations, and enabling safe, continuous operation,” with targeted upgrades to the hardware architecture to maximize the aerial endurance capabilities of the tethered system:

1. Customized top-end structural modifications to ensure the stable operation of long-distance relay equipment.

Special structural modifications have been implemented on the top surface of the FC100 chassis, along with the custom fabrication of a dedicated relay equipment mounting base, ensuring precise compatibility with the customer’s relay system. The equipment is securely fastened and features an evenly distributed center of gravity, effectively eliminating any equipment vibration or displacement during prolonged hovering operations; this ensures stable relay signal transmission throughout the entire process without interfering with continuous network deployment operations.

2. Breakthrough integration of airborne modules enhances continuous endurance capabilities.

A groundbreaking industry breakthrough! By abandoning traditional external-mounted tethered module designs, this solution directly integrates the core power supply module for the tethered relay system directly into the original factory battery frame of the aircraft. This results in a more compact aircraft structure and smoother flight attitude, effectively mitigating power fluctuations caused by wind interference from external equipment, ensuring continuous and stable power supply for the tethered mission duration, and providing comprehensive reliability for all-weather relay operations.

3. Comprehensive optimization of cables to eliminate potential risks related to battery life and relay operations

The system features newly designed battery and tethered power supply as well as signal transmission lines, eliminating all redundant cables and ensuring organized, concealed cabling layouts. This approach completely eliminates the risks of cable tangling, wear, or loosening during prolonged operations.thereby ensuring reliable continuous power supply while preventing relay disconnections or signal latency caused by line interference, and comprehensively enhancing the feasibility of extended-range relay operations.

The DJI FC100 series tethered drone relay modification solution addresses three core pain points: short aerial flight duration, inability to maintain continuous surveillance, and unstable signal transmission. Leveraging eight years of accumulated tethered drone technology expertise combined with customized hardware modifications, this solution delivers professional-grade high-altitude relay capabilities featuring unlimited flight range, 24-hour airborne operation, wide-area coverage, and highly stable data transmission.

In the future, Weize Remotely Controlled Systems will continue to deepen its research and development in long-duration remotely controlled aerial operations, iteratively optimize compatibility solutions for multiple aircraft models, and provide more professional and practical all-weather high-altitude communication support services for scientific research, emergency response, and specialized industries.

   This solution utilizes the Weize tethered ground-based power supply unit G40PRO combined with the airborne module WF36.
