RFD868ux Telemetry System Kit Modem
RFD – to flagowy produkt australijskiej firmy
RFD is a long-range telemetry and communication system. The RFD system consists of RFD modems, a set of antennas and the cables necessary to connect the modules to other systems.
At the heart of each system are RFD modems, which are high-performance radio modems operating in the ISM (Industrial, Scientific and Medical) band. They are designed for long-range communications applications requiring best-in-class radio link performance. One of the modems is always part of the GCS (Ground Control Station), while the other is part of the project with which communication is required, such as an unmanned aerial vehicle.
For more on RFD modems, their differences and applications, see our authoritative article.
RFD TXMOD 868ux module
Designed to work with control instruments that accept JR transmission modules. The device has a built-in WiFi module, which allows configuration and transmission of telemetry data to a computer or mobile device. JR modules are plugged into control apparatuses with JR sockets (Frsky Taranis, JR, Frsky Horus), establishing a connection between the apparatus and the unmanned aircraft transmitting PPM and Mavlink telemetry at the same time.

Software support / GCS
The software solution is an open source program called “SiK.” It has been re-implemented to fit the new processor architecture available on the 32-bit ARM processor core. The boot loader and interface are available for further development and firmware updates of the modem via the serial port. Most parameters can be configured via AT commands, such as baud rate (air / uart), frequency band, power levels. Integrated RFD868 radio configuration support is provided by APM Planner.
