## Why It Matters
Zhuhai-1 01 represents a compact, dual-purpose satellite platform combining Earth observation capability with amateur radio functionality. As a 55 kg microsatellite, it illustrates the trend toward smaller, lower-cost spacecraft that can deliver operational remote-sensing functions while supporting secondary payloads or communications experiments such as amateur radio. Operated and manufactured by Zhuhai Orbita Control Engineering Co. Ltd., the satellite contributes to China’s portfolio of commercial and technical small-satellite activity and demonstrates the use of microsatellites for mixed missions. Its launch on a Long March 4B from Jiuquan in mid‑2017 places it within a wave of modern satellite deployments where nations and private entities increasingly rely on agile, lower-mass platforms to expand observation coverage, test technologies, and provide niche services without the expense of larger spacecraft.

## Notable For
- Being a dual-role platform: Earth observation satellite and amateur radio satellite in a single microsatellite.  
- Small form factor: mass of 55 kg, consistent with the microsatellite class.  
- Chinese-built and -operated: manufactured and operated by Zhuhai Orbita Control Engineering Co. Ltd.  
- Launched on 2017-06-15 by a Long March 4B from Jiuquan Launch Complex 43/94.  
- Holds multiple standard identifiers: COSPAR 2017-034D and SCN 42761.
