Hey, there are so many options! Don't panic, choose GK-2A LRIT.
From AI:
LRIT (Low Rate Information Transfer) imagery: relatively low resolution. Typically, its spatial resolution may be in the range of kilometers, for example, commonly around 1.1 kilometers. This means that each pixel in the image represents a larger area on the ground, and it has limited ability to display fine details.
HRIT (High Rate Information Transfer) Cloud Map: High resolution. Its spatial resolution is typically several hundred meters or higher, such as 0.5 kilometers. The high resolution allows the cloud map to clearly display the shape, structure, and subtle features of clouds, providing more detailed information for meteorological analysis and forecasting.
RTL devices can only receive LRIT; HRIT requires larger antennas and wider bandwidth, which we will be able to provide later.

Wow, so many things are coming up! Don't panic at this point; it means the decoder is running and starting to process the signal. It will automatically track and decode the signal once it detects one.
The only thing we need to pay attention to is here.
If there's a signal, this has already responded, and the constellation map will change its form.
The satellite performs remote sensing every 10 minutes, and then takes about 3 minutes to download the LRIT cloud map. The SNR (signal-to-noise ratio) must be stable throughout this process; otherwise, gray lines and black blocks may appear (even if the computer's performance is not sufficient).
This is what happens when there is a delay or unstable signal.
