CHIRANJIB KAR

System Engineer | DRDO-ITR

System Engineer at DRDO-ITR — mostly busy building desktop applications and writing Python automations to take the boring bits off the team's plate. Currently learning the ropes of NAS server infrastructure, and running side-quests on LLM-based datasets with Ollama. Designing neon-soaked websites everyone actually wants to use by night — easy on the eyes, hard to forget.

  • Ship offline Python desktop apps for the team — UIs for AGC analysis, coverage plotting, time sync, network ops, frame parsing. Packaged with Nuitka so they run on air-gapped Windows machines with no installer and zero dependencies.
  • Study and decode telemetry file formats — IRIG 106 Chapter 10, MIL-STD-1553, PCM and more — turning that knowledge into HILS (Hardware-in-the-Loop) replay tools and decommutation utilities.
  • Manage the Manthan NAS infrastructure — HPE DL380 Gen10 boxes running RHEL 7.9 in fully air-gapped racks. LVM-partitioned 87 TB arrays, Samba shares across four static IPs with group-based access control. Basically running our own private "cloud" across the office.
  • Side quest into AI / ML — exploring local LLMs via Ollama and other open-source models, prototyping offline-friendly tooling that could one day live on-prem next to the ground-station stack. No data ever leaves the building.
  • Drive the team's "neon cyberpunk" design language across every tool — programmatic icons, custom dialogs, typewriter splashes, dark-mode everything. Engineers actually want to open these apps.

FRAME EXTRACTOR

Telemetry Frame Range Investigator · NeonCircuit v5

Desktop tool that parses telemetry exports from PDF and TXT, pulls frame and word number ranges, generates investigation reports, and exports CSVs. Shipped 1200+ lines of PyQt6 with 10 documented fixes co-reported with a teammate — tightened parser, themed NeonConfirmBox dialogs, progressive button states, sorted-unique word caching.

TIME SYNC

CDT / ATD Receiver · Sync · Relay

UDP listener on port 7000 that parses 27-byte timing packets at 20 Hz — ATD (Absolute Time Data) + CDT (Count Down Time with D/H/U status flags). Displays both in color-coded panels (RED countdown, YELLOW hold, GREEN count-up), captures Lift Off on transitions, syncs PC clock to ATD via SetSystemTime (IST-aware), and relays packets to other LAN PCs not on the timing department's whitelist. Zero external deps, 6.5 MB PyInstaller exe.

DRDO Network Command Center · 6 Tabs

All-in-one LAN admin console — IPv4 config with duplicate-IP collision warnings, ON/OFF adapter toggles, ping (single or continuous), netstat connection viewer, port lookup, and a Traffic Monitor that polls netstat -ano every 500 ms with Hz-based color coding (green 1Hz, orange 5Hz, red 15Hz suspicious) plus per-adapter byte rates via PowerShell. Programmatic LAN-topology icon, custom canvas dialogs, toast notifications, typewriter dev credit. Zero external deps.

Multi-Station AGC Signal Analyzer · 1520 LOC

Tkinter app that parses 10 predefined station formats (BHTM, FTM, GRS-1/3, HGTM, KATM, MGTM-D/N, PATM-2, SBTM) + Custom mode, auto-detects AGC and time columns, and plots in three modes — Single, Multiplot (≤4 params), Subplots (2–8). Universal regex time parser, Lift Off Time (LOT) input that puts T-0 at launch (pre-launch negative, post-launch positive), click-place data cursors, scroll-zoom, drag-pan, stats panel (Min/Max/Avg/Std), 200 DPI PNG export. Accepts .txt / .csv / .xlsx.
