What is the 3m3u camera:
The 3m3u camera is designed for small CubeSat platforms, specifically the 6U CubeSat configuration. It is a compact, low-resolution camera suitable for high temporal resolution and large-scale satellite network scenarios. The camera supports both pushbroom and staring video modes，which is an ideal for advanced satellite imaging and observation tasks.
