More Software Defined Radio Projects Using DragonOS

DragonOS, a Debian-based Linux distribution specially packaged for software-defined radio functionality, broke into the waves during the onset of various pandemic lockdowns last year. Since then, [Aaron], the creator of the operating system, has been busy adding features to the distribution as well as making many videos that showcase its capabilities and also act as instructions for people who may want to learn about software-defined radio. The latest is a video about using this software to detect radio signals in certain ranges.

This build uses two RTL-SDR devices paired with the DragonOS software suite to automatically detect active frequencies within a specified frequency range that also exceed the threshold measured above the average noise floor. The video covers the software configuration and its use to detect these signals, but also the influxdb and Grafana configuration which also provide logging functions. Using this configuration, many receivers, both local and over the Internet, can be configured to dump all identified frequencies, powers and timestamps to DragonOS.

[Aaron] has also assisted developers with the development of the SDR4space.lite application which includes GPS support, so he hopes that in a future video the user will be able to easily associate location with identified frequencies. Projects like these also serve as a reminder that getting into software-defined radio is as simple as purchasing a $ 10 USB radio receiver and setting up free software to do whatever you can imagine, such as tracking ships and planes in real time .

One day it may be possible to digitally sample signals directly from the antenna while maintaining a high dynamic range.

What does software defined radio mean? A Software Defined Radio System (SDR) is a radio communication system that uses software to process various signals (modulation, demodulation, decoding, etc.) instead of the traditional hardware components that are typically created for these dedicated tasks.

What are the advantages of software defined radio?

One of the main advantages of SDR technology is that it can be configured to exactly meet the user’s requirements – minor changes to the software can make the radio exactly match the requirements.

What is Software Defined Radio in cognitive radio?

Software-defined Radio & Cognitive Radio SDR is an implementation of a wireless platform whose functionality is based almost entirely on executable software, unlike conventional wireless devices where both digital signal processing and digital communication algorithms are implemented using integrated circuits.

What is cognitive radio engine?

From Wikipedia, the free encyclopedia. Cognitive Radio (CR) is a radio that can be dynamically programmed and configured to take advantage of the best wireless channels nearby to avoid user interference and congestion.

What is software defined and ultra wideband radio?

Summary: This paper proposes a software defined radio receiver (SDR) architecture for ultra wideband (UWB) applications. Both data transmission and UWB positioning functions are implemented on a single hardware platform and using appropriate demodulation and positioning algorithms.

What is the difference between a traditional radio and a software defined radio SDR?

Software defined radio differs from traditional radio in several ways. The biggest difference is in the method of RF detection and demodulation. SDR uses a quadrature sampling detector (QSD), which splits the incoming waveform into in-phase signals or (I) and a quadrature signal (Q).

How does a SDR work?

The value of the SDR is determined daily by the IMF on the basis of the constant currency amounts of the currencies in the SDR basket and the daily market rates between the currencies in the SDR basket. SDRs are allocated only to IMF members who choose to participate in the SDR Department.

What is SDR radio?

Software Defined Radio is a radio in which the characteristics of the carrier frequency, signal bandwidth, modulation, and network access are defined by software. Modern SDR also implements all the necessary cryptography, forward error correction coding, and voice, video or data source coding in the software.
