RFD - the flagship product of the Australian company RFDesign
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 RFD - system telemetrii i komunikacji dalekiego zasięgu.

SOFTWARE OPERATION / 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.
