Technologies - Custom Software Defined Radios (SDR) from 10 kHz to 6 GHz and Beyond
Software Defined Radio (SDR) technology enables flexible and reconfigurable wireless communication systems by implementing most signal processing
functions in software rather than dedicated hardware.
Acies designs and manufactures custom SDR receivers, transmitters and transceivers covering frequencies from ELF and HF up to VHF, UHF and microwave
bands including L, S and X bands. Our solutions combine high-performance RF frontends with FPGA and embedded processing to support demanding aerospace,
industrial and scientific applications.
Applications
Our SDR technologies can be employed in a wide range of applications:- Satellite communications;
- GNSS signal acquisition and analysis;
- Telemetry, Tracking and Command (TT&C);
- Earth observation payloads;
- Spectrum monitoring and signal intelligence;
- Industrial wireless systems;
- Scientific instrumentation;
- Experimental and educational platforms.
You can find this example on github. In order to execute it, youd need GNU radio and an ADALM-Pluto. It can be easily modified fpt other SDR. Tested on Manjaro/GNU/Linux.
Flexible architecture
Our SDR solutions are based on a modular architecture that allows:- custom RF frontends;
- FPGA-based digital signal processing;
- real-time embedded software;
- GNU Radio integration;
- support for multiple communication standards;
- rapid prototyping and custom waveform implementation.
Example: GPS L1 receiver
As an example of our SDR capabilities, we developed a GPS L1 frontend including a custom-designed antenna and signal processing chain.The receiver can be tested using commercially available SDR hardware such as HackRF One or Analog Devices ADALM-Pluto and open-source tools including GNU Radio and Gqrx.
The complete project is available on GitHub and can be adapted to other SDR platforms for experimentation and further development.
We design and manufacture custom receivers, transmitters, transceivers, form ELF to VHF, UHF, microwaves (L, S, X bands). Here an example of a GPS L1 frontend, with custom designed antenna, seen with HackRF One and Gqrx.
Signal analysis
The SDR processing chain provides real-time visualization of received signals and spectrum characteristics, enabling:- frequency-domain analysis;
- noise floor estimation;
- signal-to-noise ratio evaluation;
- carrier detection;
- demodulation and audio recovery.
Here is what you see when executing the flow graph. Needless to say, you can hear your favorite station using loudspeakers or headphones.
