Jiaming chart machine can't find the stars.

What the subject wants to ask is why Jiaming Haitu can't find the satellite signal? The weather is bad.

1. Because the satellite is beyond the earth, the signal can only reach the ground through the atmosphere, so the weather will affect it, such as clouds and magnetic fields.

2. Based on the above analysis, Jiaming chart machine can't find the satellite signal because the bad weather affects the signal transmission.
