2005-024A
SJ-7 carried space environment detectors. Expected life span was three years. The satellite is also called Tansuo-2 and so may be related to Tansuo-1 (SW-1).
Phillip Clark was the first to note in public that the satellite made small orbit adjustments, raising and lowering the orbit by 10 km or so, staying in the 550-580 km altitude regime. The eccentricity varied while the orbital period remained relatively stable.
SJ-7 may have been a Shanghai satellite. The satellite was used as a target satellite in 2013 and 2014.
