The new Long March 11 (CZ-11) launch vehicle was launched for its maiden flight on 25 September at 01:41 UTC from Jiuquan with four satellites on board. Three of those are planned to have 2 m, 70 cm and 2.4 GHz downlinks. The 70 cm downlink frequencies have been published by BD5RV.

TW-1A (TianWang 1A, SECM-1), a 2U Cubesat TW-1B (TianWang 1B, NJUST-2), a 2U Cubesat TW-1C (TianWang 1B, NJFA-1), a 3U Cubesat.

The TW-1 satellites will test formation flying, evaluate a SDR payload, and test a GPS/Beidou receiver, AIS receiver, ADS-B receiver and a video camera.

The TW-1 satellites are in polar orbits, 470 x 485 km, 97.3 degrees inclination. Their IDs are in the object range 40925 to 40928 (i.e. 2015-051A to 2015-051D).
