A dish. A satellite. A log.
A one-metre offset dish on a rooftop in Lucknow, pointed thirty degrees up and a hundred and twelve east of true. It listens to a single geostationary weather satellite and writes the pictures down.

Recent plates

Plate II 2026-05-19 · 02:10ZEarly morning IST. Sun terminator falls across the Pacific; dawn over Japan.
-
Plate III 2026-05-19 · 01:30ZSouth Pacific clear; eastern Australia under cloud. The CADU stream held lock for the full slot.
-
Plate IV 2026-05-18 · 13:20ZThe cyclone over the Bay of Bengal is the kind of feature this whole stack exists for.
-
Plate V 2026-05-18 · 13:20ZThe same capture as Plate I, before Sanchez. Greyscale IR brightness, no underlay, no projection compensation. This is what SatDump emits.
The instruments
Each plate is the output of one of three configured chains, run end-to-end without intervention. When a node breaks, the chain stops and the log entry says where. See all three instruments →

| 19 | 2026-05-18 · 17:19Z | GEO-KOMPSAT-2A | No lock | L | — | 0 KiB | 5-second test capture from Pi. No CADU output, deframer NOSYNC, viterbi NOSYNC. Short duration likely insufficient for lock. |
| 18 | 2026-05-18 · 14:39Z | GEO-KOMPSAT-2A | No lock | L | — | 0 KiB | FREQUENCY ERROR: tuned 1691.000 MHz but GK-2A requires 1692.140 MHz (1.14 MHz low). Good signal quality at wrong freq, Viterbi locked but deframer failed. Pi script needs frequency correction. |
