ZDPS 1 [Zhejiang University]
The Zhejiang University's ZDPS 1 (Zheda Pixing) series of picosatellites were the first Chinese picosatellites.
The ZDPS-1 and 1A satellites were built as 15 cm × 15 cm × 15 cm cubes with a weight of 2.5 kg for ZDPS-1 and a weight of 3.5 kg for ZDPS-1A-01 and ZDPS-1A-02 each.
Their purpose is to demonstrate pico-satellite technologies:
- an Universal S-Band (USB) TTC system
- an active tri-axial stabilizing attitude control
- a CMOS camera for panoramic Earth imaging
ZDPS-1 was launched as a piggy-back payload in 2007, but was apparently not successful.
ZDPS-1A-01 and ZDPS-1A-02 were both jointly launched in 2010 as piggy-back payloads and were the first pico-satellites that have been launched successfully in China. After two years successful in-orbit operation, main components of ZDPS-1A still work well.
