GS. — A ground-station log

Frontier work · decodes in progress

Reading signals nobody has read yet

Five downlinks we are actively pulling apart from this station. Each one reached a point where the public tooling stops, and the rest had to come from the bytes themselves. This is the working face, not a finished archive. Each card opens its own decode.

  1. GGAK-E · L2 decode preview
    GGAK-E · L2 Decoded and validated

    Reading a weather satellite's radiation monitor

    Elektro-L2 · 1693 MHz

    A byte-level decode of Russia's GGAK-E space-weather telemetry, validated channel by channel against the published SINP data.

  2. GGAK-E · L5 decode preview
    GGAK-E · L5 Decoded from our own dish · instruments read

    The first one we caught ourselves

    Elektro-L5 · 1693 MHz

    The L2 work read someone else's recording. This time we received the sibling satellite on our own dish, decoded it twice over on independent chains, and read through to the instruments inside: both particle detectors' energy-sweep spectra, off our own antenna.

  3. FY-4A LRIT decode preview
    FY-4A LRIT Waveform solved · decoder validated · SNR-limited

    A Chinese geo downlink, measured from scratch

    FengYun-4A · 1697 MHz

    Built from the air after the bird switched its symbol rate and the public tools stopped locking it. We measured the real waveform and proved the decoder on a reference recording. The wall now is signal strength, not the code: the 60 cm dish is too small to pull the image.

  4. GK-2A ADD decode preview
    GK-2A ADD Decoded · 13 products + schedule

    An undocumented weather-chart channel

    GEO-KOMPSAT-2A · 1692 MHz

    The Korean LRIT downlink carries a second data channel of KMA charts alongside the imagery. Decoded from one overnight recording, with the daily operation plan in plain text.

  5. GK-2A · scale law decode preview
    GK-2A · scale law Measured · scale-invariant

    Storm clouds with no typical size

    GEO-KOMPSAT-2A · 10.3 micron

    From one thermal-infrared band, decoded here, tropical storm clouds over the Pacific warm pool show no characteristic size: a power-law temperature spectrum and a power-law cluster-size distribution, both steady for hours and reproducing across days.
