Introduction

TT-3 is launched successfully in September, 2015.
TT-3 satellite accomplished cluster flying of “1 main satellite + 5 sub-satellites”. At the same time, it also realized the first domestic on-orbit receiving test of ADS-B signal, the first PhoneSat and FemtoSat on-orbit test, and new generation AIS receiver on-orbit test.  TT-3 has made a breakthrough on-orbit release of the sub-satellites from the main satellite, space ad hoc networks and other key technologies, as well as on-orbit verification of TT&C transponder, infrared camera, sun sensor, micro solid state driver and other components.
