DSP-21

 2001-033A

---

DSP-21 launched by Titan 4B-31 with the IUS-16 upper stage. Shortly afterwards, DSP 17 vacated the 103E position and was replaced by DSP 18 which moved there from the 70E position; it seems a reasonable assumption that DSP 21 occupied the prime 70E Indian Ocean position.

DSP 21 carried a sensor to detect space weather related anomalies.

Shiyan

 2004-046A

---

Shiyan-2 was launched by CZ-2C from Xichang. The 300 kg remote sensing satellite was developed by DFH Satellite Co. It is also known as Qianshao 1,

\uni{ 前哨.}{ }

A large piece of debris (2004-046G) was tracked in a 662 x 697 km orbit in Dec 2004 but not subsequently; this may have been an erroneous cataloging.

Shiyan 2 was a scientific experimental microsatellite, 300kg, based on platform CAST2000, developed by DFHSat. It has high precision control systems and rapid slewing capability. The satellite validated the the bus technology for scientific experimental small satellites; 6 new technologies were demonstrated: high precision control, integrated satellite systems, high efficiency battery, multi-function structure, etc It also tested infrared sensors, possibly for the SJ-11 series, and according to Lissov (nasaspaceflight.com) a signals intelligence payload.

On 2007 Jul 4 the satellite's orbit changed slightly, lowering by 2 km. This may represent an end of life maneuver. However it was reported to be operating in 2010.
