Disclamer:

I am not an expert! I have tried to make this document as accurate as possible but there may still be inaccuracies, I have cited sources where possible. If you think I have made an error please open an issue on the github repo with what I have done wrong

NOAA 15

NOAA 15: Downlinks: APT (Automatic Picture Transmission) Frequency Modulation SymbolRate Status 137.620MHz Analog N/A On Notes: APT Channel A: AVHRR channel 2 APT Channel B: AVHRRR channel 4 DSB (Direct Sounder Broadcast) Frequency Modulation SymbolRate Status 137.350MHz BPSK TODO On Notes: All HIRS and SEM channels + some satellite telemetry Instruments: AVHRR/3 (Advanced very-high-resolution radiometer) Status Degraded Channels light wavelenghts: Channel 1 Visible Green-Red (0.58 - 0.68 µm) Channel 2 Near IR (0.725 - 1.00 µm) Channel 3 Near IR (1.58 - 1.64 µm) Channel 4 Mid IR (3.55 - 3.93 µm) Channel 5 Far IR (10.3 - 11.3 µm) Channel 6 Far IR (11.5 - 12.5 µm) From space.oscar.wmo.int Notes: HIRS/3 (High resolution Infrared Radiation Sounder) Status Ok Channels light wavelenghts: Channel 1 Far IR (14.95 µm) Channel 2 Far IR (14.71 µm) Channel 3 Far IR (14.49 µm) Channel 4 Far IR (14.22 µm) Channel 5 Far IR (13.97 µm) Channel 6 Far IR (13.64 µm) Channel 7 Far IR (13.35 µm) Channel 8 Far IR (12.47 µm) Channel 9 Far IR (11.11 µm) Channel 10 Far IR (9.71 µm) Channel 11 Far IR (7.33 µm) Channel 12 Far IR (6.52 µm) Channel 13 Mid IR (4.57 µm) Channel 14 Mid IR (4.52 µm) Channel 15 Mid IR (4.47 µm) Channel 16 Mid IR (4.45 µm) Channel 17 Mid IR (4.13 µm) Channel 18 Mid IR (4.00 µm) Channel 19 Mid IR (3.76 µm) Channel 20 Visible Red (0.69 µm) From space.oscar.wmo.int Notes: SEM Status Ok I can't be bothered to do this one see SEM/MEPED and SEM/TED Notes: Notes: NOAA 15 is the only active POES satellites that has the older HIRS/3 instead of HIRS/4 Log: 2023-08-28 The AVHRR scan motor appears to be stuck, corrupting the main image data. The MIRP (onboard computer) does not seem capable of using this data and makes an unsyncable APT signal
