ACQUIRING FIX
Bucharest · The studio of Miluță Flueraș
Where coordinates meet light.
One studio, four frequencies. We build software that keeps GNSS signals honest to the centimetre, photograph the loudest stages in Romania, and ship the tools in between — open-source signal analysis, processing pipelines, and a festival app born in the photo pit. Precision and perception, in the same pair of hands. This is where science becomes art.
Act I — Photography
Official photographer on Romania’s biggest stages — Electric Castle, ARTmania, Rockstadt Extreme Fest, DefCamp, Balkanik Festival — and co-founder of the Stage Photo Association. Director of “Insight: An Eye on Bucharest’s Art Galleries”. Commercial work for Toyota Romania, McCANN, BrandFusion, Global Records, Greenpeace and F64.
Act II — Geodesy engineering
The day job, for the record: our founder serves as Head of Geodesy at Romania’s National Center for Cartography, coordinating ROMPOS — the national GNSS reference-station network — and representing Romania as a EUPOS voting member since 2018. That work belongs to the institution.
Shutter Symphony is a different thing. Everything below — the entire GeoVeil ecosystem — was designed, written and operated by one engineer, on his own time, his own servers, his own dime: eight independent instruments for GNSS defence and quality, built outside any state institution and offered back to the field.

IGeoVeil Live
geoveil.ro · api.geoveil.ro/v2
Interference intelligence across 83 NovAtel OEM7 reference stations — ~28 million RF telemetry samples a day. Six-level PSD threat grading calibrated on 57,874 real events, a seven-indicator spoofing engine that separates jamming from meaconing, sweep detection with MHz/s drift tracking, VADASE displacement alerts, and dual ML forecasting — LightGBM (AUC 0.981) beside an LSTM — predicting the next 24 hours per station and band.
SeptoVeil
SK01–SK10 · Septentrio PolaRx5e network
RF threat intelligence that refuses to trust hardware flags: raw baseband I/Q pulled off every receiver and pushed through its own 60 MHz FFT at 2-second cadence, every detection threshold tunable live. Events are cross-correlated against the ROMPOS network and the national spectrum regulator, Galileo OSNMA authentication is watched for spoofing, and a calibrated LightGBM on 31 engineered features forecasts the next hour — per station, per band, with expected frequency and bandwidth.
GeoVeil RTKNMA
CORS integrity · anti-spoofing · zero extra hardware
Every station's own RTCM stream replayed as a rover against a 0 km virtual reference: 88 streams verified at 1 Hz to ~6 mm. Per-satellite C/N₀ read raw from the RTCM bits (DF403) before any firmware can smooth it, four weighted detectors fused into one spoofing score, and automatic regional escalation when ≥3 stations within 100 km flag inside 120 seconds. Virtual rovers at 10/20/30 km prove customer-grade accuracy continuously. Production false-positive rate: zero.
GeoVeil RINEX
geoveil-rinex.eu · v2.0.7
Upload RINEX 2.x/3.x for automated processing through Anubis QC, gnss-tec ionosphere analysis, and multipath detection. Auto-merges hourly files, fetches IGS data, generates comprehensive PDF reports.
GeoVeil Batch
batch.geoveil-rinex.eu
The geoveil-cn0 engine at network scale: hundreds of RINEX files per session fan out over a Celery + Redis worker fleet with live WebSocket progress, MongoDB + MinIO storage, and folder-watch ingestion. Network-wide quality assessment, temporal trends, and automated reporting across entire station inventories.
geoveil-cn0
PyPI · open source · MIT · Rust core
Python library with a Rust core (PyO3): a full day of 1 Hz observations — 86,400 epochs — scored in ~3 seconds. Composite 0–100 quality score and three independent detectors: jamming (Stanford drop-rate, >6 dB in <3 s), spoofing (C/N₀ uniformity), interference (ITU-R M.1902-1). Six constellations, RINEX 2/3/4 + Hatanaka, zero-dependency wheels. In production across 60+ ROMPOS stations — the panel above speaks its language.
geoveil-mp
PyPI · open source
Multipath analysis from RINEX observations. MP1/MP2 combinations, cycle slip detection, satellite visibility metrics for station environment assessment.
georeper.app
georeper.app
Geodetic reference point finder for field surveyors. Search, locate, and navigate to nearby control points with real-time distance calculation and detailed point information.
Act III — Software
Beyond geodesy, we design and ship product software end to end — backends, pipelines, and apps. The newest one comes straight from two decades in the photo pit.
GigGrid
Plan the show. Run the show.
A festival companion with two faces. Fans see every stage on one live timeline — favourites, reminders, fully offline when the network dies in the crowd. Crews run the same grid from the other side: deployments, check-in verification, timed cues for pyro and lights, and AI-powered schedule import from any URL or file.
Built by someone who has watched over national-grade signals — and stood in the pit when the lights went down.
Act IV — Record
Degrees, mandates, certifications and the rooms where the work was presented. In writing.
