Web-Spectrum: Web-Based Spectrum Analyzer and GPS Signal Analyzer with RTL-SDR Support

Over on GitHub we've recently seen a new open source program release called "web-spectrum". Web-spectrum is a multi-purpose browser-based tool. One interesting feature is that it allows you to view the GNSS spectrum (via a connected RTL-SDR or SDRplay with an appropriate antenna), decode it to a position, and also analyze the signal for jamming. It uses gnss-sdr or Gypsum as the backend GNSS processing tool.

The tool can also be used as a real-time spectrum analyzer, and for this, it supports RTL-SDR and SDRplay as well as the tinySDR Ultra spectrum analyzer.

Finally, in addition to GPS decoding, it also supports ADS-B and ISM band decoding.
