working on my weather Visualizer project and the real-time alert system flipped the screen to Tornado Warning...
unexpected, but nice to know it works.
(lower banner had not yet caught up to the alert)
#wxtwitter#tornado
This is kinda cool.
Added capability for the Airspace Visualizer to display various satellite constellations... Starlink, Iridium, GNSS/GPS, anything for which you can acquire the TLE data.
Here's a Starlink snapshot...
Pre-release!
Airspace Visualizer is now on GitHub โ ADS-B + VDL2 + AI assistant.
- LInux (Windows w/minor tweaks)
- Real-time aircraft display
- Semantic RAG + chat
- Geospatial overlays
- Built for local data feeds

Early, rough, and ready for you
This is a fun project I'm finishing up... it's called RadarScope.
RadarScope takes #ADSB data from #dump1090 and #ACARS data from #dumpvdl2 and displays it on a vintage green scope display.
It correlates and embeds the ADS-B and ACARS messages for use by #AI.
Surface features
Yesterday I shared a CUDA-based FFT utility using cuFFT on the CPU and power spectrum calculation on the GPU.
Not happy with CPU % utilization so I moved all of the FFT/PSD pipeline to the GPU.
CPU % declined dramatically and GPU % increased only slightly (as expected).
Airspace visualizer app update: CLOSE! finishing touches to make data feed reliable.
API to fetch local geographic data when user lat/long is entered - working with OpenStreetMap
AI chatbot - working for ADS-B and VDL2 data, sample queries below
You'll need a ADS-B decoder
along the way to building a CUDA-based #Iridium burst detector I wrote this CUDA FFT utility. just pipe an IQ stream to it on the command line. adjustable frequency markers, center freq, sample rate, etc.
some Iridium bursts received by #Airspy R2
CUDA-based FFT visualizer example showing 3 instances running simultaneously. FFT size = 65536. Best of all, nvtop showing total GPU utilization of only 6% so plenty of compute headroom remaining for other stuff. I've compiled and tested with FFT sizes up to 1M
#SDR#DSP#FFT
CUDA-based FFT visualizer continued. same IQ stream as before: cf32 #Iridium bursts on the #Airspy R2
this version adds Y-axis labels, dynamic range control, and reference level control.
as you can see in the video I need to dial in the reference level control so we don't clip
Update: Due to feedback, I'm renaming the project!
What started as โRadarScopeโ has evolved into something broader: a cross-platform, AI-assisted airspace awareness tool that integrates โ๏ธ ADS-B, ๐ก ACARS, and (soon) ๐ข AIS for maritime interests.
New name reveal soon. Thanks
Easy #SDRsharp on #Ubuntu 22.04
Get current SDR# from airspy.com/download and unzip
Get a Wine 7.0 AppImage github.com/mmtrt/WINE_Appโฆ and save to sdrsharp-x86 directory
sudo apt install libfuse*
sudo chmod a+x *Image
./wine-stable_7.0.1-x86_64.AppImage SDRSharp.exe
Got the Iridium ACARS feed going on Ubuntu 22.04 using an Airspy SDR and RTLSDR L-band patch antenna which play together quite well.
A few aggravations making the scripts work but good result in the end.
Next up is Inmarsat.
Thanks to @thebaldgeek for his help today.
