Optical Signal Conversion Unit «ASTRALEXPRESS» (Optical RX + VTX Rush Max Solo 5.8G 2.5W + RX 2.4G + Foxeer Lollipop 5.8G)

We offer the Astral Express brand ground control unit for professional use in drone systems and signal relay. The device is designed as part of the Ground Relay Stations category and is intended for reliable and secure control of unmanned aerial vehicles via a fiber optic reel. The unit converts an optical signal into a comprehensive solution for control and video transmission, combining an Optical RX, a VTX Rush Max Solo 5.8G 2.5W video transmitter, a 2.4G receiver, and a Foxeer Lollipop 5.8G video camera/antenna.

Advantages and Capabilities

The main advantages of using a fiber optic connection are: interference immunity, high protection against EW and SIGINT systems, stable operation in complex conditions, and support for operation at distances up to 30 km. The unit allows operation in two modes: control and video can be transmitted via fiber optic cable or radio channel, depending on the task and operating conditions.
The device is equipped with a built-in ELRS 2.4 GHz receiver for receiving control signals and also supports direct connection from equipment via cable, ensuring a maximally reliable and confidential communication channel.

Functional Capabilities:

• Two operating modes: fiber optic channel and radio channel for video and command transmission;
• Support for RCA connectors for image transmission, adding flexibility when connecting external displays or recorders;
• Built-in ELRS 2.4 GHz receiver or cable control for enhanced security and compatibility with pilot equipment;
• Compatibility with Foxeer Lollipop 5.8G for video signal transmission and with VTX Rush Max Solo 5.8G 2.5W with power and channel switching capability for optimal signal level;
• Support for 1310/1550 nm wavelength for fiber optic channels.
