HEAD-2A/B or Hede-2A/B is a Chinese commercial satellite by HEAD Aerospace to track ships receiving their AIS (Automated Identification System) signals.

The three-axis stabilized satellites are built by SAST (Shanghai Academy of Spaceflight Technology) and feature a high-performance AIS-receiver capable of processing 2 million AIS short messages and identifying 60000 ships per day.

HEAD-2A/B also serves as a prototype for the Skywalker constellation, which is to be a commercial small satellite-based constellation supporting multiple applications.

TY 16 (Tianyi 16) and TY 17 (Tianyi 17) are a pair of commercial earth observation nanosatellites developed by Spacety Aerospace Co. at the Changsha Gaoxinqu Tianyi Research Institute, Hunan.

These are medium-resolution remote sensing satellites to carry out satellite data applications such as disaster emergency monitoring, maritime applications, agricultural remote sensing services, and polar environmental monitoring.

Tianqi (also transcribed Tiange) is a series of small Chinese experimental LEO comsats by Guodian Gaoke for IoT communications, which also carry a camera for educational purposes.

Guodian Gaoke plans to operate an IoT constellation operation. The "Apocalypse Constellation" provides users with much-needed data collection and transmission services for terrestrial network coverage blind areas, which are widely used in marine, environmental protection, meteorological, forestry, geological, emergency, rescue, and smart city industries to enhance China's global data network coverage and application capabilities are of strategic importance.
