Zero Signal Dropouts! Skydroid GR02 Relay Receiver, a Premium Solution for UAV Beyond Visual Line-of-Sight Operations.

Terrain-induced signal occlusion amid mountainous areas and site restriction for remote takeoff and landing constitute major bottlenecks constraining UAV BVLOS missions. Signal attenuation may lead to loss of sight control, while interrupted image transmission causes invalid field operations. Such issues undermine operational efficiency substantially and bring about tangible flight safety risks.

To address these longstanding operational challenges, Skydroid unveils its flagship new product - the GR02 Relay Receiver. As a new-generation premium relay receiver engineered to resolve UAV control issues under harsh and complex terrains, it enables extended flight range, reliable flight control and enhanced operational safety for UAV.

Main Heading: Core Functional Highlights, Three Core Capabilities to Resolve Operational Difficulties in Complex Environments

Subheading: Dual-Band & Dual-Mode Coordination Ensures Stable Anti-Interference Signal Transmission

Adopting a coordinated 2.4G & 5.8G dual-band dual-mode design, GR02 supports simultaneous dual-band operation and establishes a dual-channel transmission structure. The master and slave receivers will synchronously receive data and video transmission. 

Integrated with an intelligent frequency allocation mechanism, the master device auto-selects the 5.8G band whereas the slave device defaults to 2.4G, requiring no manual tuning for convenient and efficient operation.

The dual-band coordination architecture efficiently prevents signal contention and electromagnetic interference within intricate electromagnetic surroundings. In sites featuring intensive multi-UAV operations and cluttered radio frequency environment, it maintains unobstructed control links, secures high stability and reliability of data transmission, and fundamentally reduces the occurrence of signal disconnection.

Subheading: Seamless Master-Slave Switchover for Flight Safety Redundancy

GR02 features seamless control switchover between master and slave receivers to build a dual-redundancy flight control system. Operators may manually initiate control transfer via pre-configured channel buttons to accommodate varying control requirements across different operational phases. In case of master receiver signal loss or link disconnection, the system automatically activates the switchover routine and shifts full control to the slave unit without interruption to ongoing missions.

This dual-mode design integrating manual active switching and automatic fault takeover delivers outstanding system redundancy. It maintains continuous controllability of UAVs amid extremely complicated operating conditions, drastically improves flight safety, and fully meets the high-reliability specifications of professional UAV applications.

Subheading：Remote Takeoff & Landing between Point A and Point B to Break Terrain and Operational Radius Limitations

Breaking the conventional constraint that UAVs must return to the takeoff spot for recovery after flight, the GR02 enables cross-site operation with takeoff at Point A and landing at Point B, greatly boosting operational flexibility. This function effectively extends the operational radius and coverage of unmanned vehicles, making it ideal for complex missions requiring traversal across rivers, canyons, mountain ranges and other geographic obstacles.

Operators can launch the UAV at Point A and land it at Point B after crossing barriers for mountain surveying, cross-regional power line inspection and other missions. This capability completely removes terrain constraints, greatly improves the feasibility and efficiency of long-distance cross-terrain operations, and delivers an innovative solution for all kinds of complex field applications.

Main Heading: Robust Hardware Configuration for Harsh Working Conditions

Beyond its superior functional performance, GR02 is equipped with robust hardware and versatile parameter compatibility to cope with diverse complex operational scenarios:

Operating Frequency: 2.4GHz & 5.8GHz

Input Voltage: 7.2V ~ 72V

Interfaces: SBUS/PWM/LAN Port/Data transmission

Operating Temperature: -10°C ~ 60°C

Dimension: 248mm×140mm×20mm

Compatible Remote Controller: Skydroid G-series remote controller

The unit is fitted with abundant ports including power input, data transmission interface, SBUS output, PWM output and SMA antenna connector to facilitate connection with various peripheral devices. During installation, users shall install extension feeder cables, fasten SMA connectors, attach shock-absorbing foam on the bottom and secure external antennas. Such mounting practices effectively mitigate vibration and airflow interference during flight, enabling stable operation under rigorous field environments.

Main Heading: Three-Step Quick Setup to Lower Operation Threshold Significantly

Balancing premium performance and user friendliness, the GR02 features a streamlined software setup procedure that allows rapid deployment without sophisticated professional expertise:

1. Upgrade the remote controller for version compatibility

  Connect the remote controller to a stable network and launch the“Device Helper”. Tap “Update Now” upon the pop-up prompt after program startup. After upgrading, verify both the wireless module and system firmware are on V2 version with identical firmware for master and slave control terminals.

Important Note: Do not disconnect wiring or cut off power during upgrade to avoid permanent equipment damage.

2. Frequency Binding Operation to Establish Device Connection

  Power on the GR02 and wait for 30 seconds, then long-press the binding button until the blue LED2 flashes rapidly. Access the frequency binding page via the device helper on the master remote controller and tap “Start Binding”; solid blue LED indicates successful connection.

3. Master & Slave Configuration to Activate Relay Mode

  Master Setup: In the device assistant of the master transmitter, navigate to “Advanced Options” → “Code: 999” → “Relay Mode”, set the unit as Master, and configure the dedicated channel for control authority switching.

  Slave Setup: Access Relay Mode on the slave transmitter in the same path, select Slave mode, then input the identical MAC address as the master to finalize slave pairing.

In-depth Adaptation to Diverse Scenarios for High-efficiency UAV Operations

Boasting robust signal relaying, anti-interference performance and seamless switchover functions, the GR02 fits a wide spectrum of UAV industrial applications and serves as a core enabler for high-efficiency field missions:

1. Power Line Inspection: It stably transmits inspection videos and data amid mountainous and hilly terrains, enabling operators to spot potential line hazards promptly and safeguard grid operational safety；
