Satellite Conjunction Risk Analysis
Analysis PipelineA pipeline for analyzing close approach risk between satellites in low Earth orbit, using public TLE data. Works with ~10,000 satellites and produces summary statistics for high-risk pairs.
Most of this started because I needed it for my research. Some of it became its own thing.
A few things I built:
A pipeline for analyzing close approach risk between satellites in low Earth orbit, using public TLE data. Works with ~10,000 satellites and produces summary statistics for high-risk pairs.
A modular pipeline for extracting relative photometry from ground-based CCD images — calibration, alignment, WCS-based source matching, aperture photometry, and light curve output.
Compares SQM-L sky brightness readings from the field against NASA VIIRS satellite data. Maps local variation and puts ground-truth measurements alongside satellite-derived estimates.
A searchable database of model parameters for polluted white dwarf systems. Look up stars by name, filter by model choices, and inspect fit results directly in the browser.
I write code that I'll still understand in six months, and that someone else could pick up without a walkthrough.
My GitHub has the satellite and photometry projects above, plus Stellarium scripts I use for public nights, this site, and a few other things. Most repos have a README that explains what the code does and why I wrote it.
