NJUST II CubSat Starts Working in ISS!


        At 13:25pm on May 25th, Beijing time, the NJUST II CubSat developed by the micro-nano satellite team of NJUST, was catapulted via the international space station (ISS) and began to work officially. At 17:41pm, amateur radio enthusiasts in Japan received the downlink signal of NJUST II for the first time. At 19:13pm, the satellite passed over Nanjing for the first time, and the Nanjing ground station conducted uplink and downlink two-way communication with it, and its status was good.

        NJUST II micro-nano satellite is a dual-CubSat independently developed by NJUST, which adopts the international CubeSat design standard and weighs 2.3kg. It is equipped with MEMS-based micro-nano satellite sensors and executive components independently designed by our university, as well as satellite management and attitude control computer based on the embedded system, communication transceiver, power supply system and its micro-strip antenna.

        On April 18th, this satellite, after being developed for more than 4 years, along with the other 27 CubSats for the international QB50 project, was launched on the Cosmic 5 rocket/Cygnus cargo spacecraft to the ISS.

        On the ISS, in addition to low-thermal atmospheric detection mission, “NJUST II” also carries out on-orbit demonstration of the new nano-satellite platform, feasibility of COTS devices in space applications, deployable windsurfing technology and zero momentum control and other technologies of micro-nano satellites.

        “NJUST II” is a sub-project of the flagship Project QB50 under the EU's Seventh Framework Agreement. The QB50 Project was initiated by the top international scientific research institution and universities around the world were invited to participate in the 90-300 km atmospheric exploration program, and planned to launch 50 micro-satellites. In April 2012, NJUST officially joined the Project after passing the expert evaluation of the EU.

        NJUST is one of the earlier universities that developed CubSat in China, so far, 4 small satellites have been launched in less than two years. The successful launch of the 4 satellites including NJUST II marks a new level of our comprehensive strength in the field of micro-nano satellite research and development, and enables us to compete with the world's high-level universities in the international space field. It is of great practical and far-reaching historical significance to our university’s the talent training for space engineering, space science research, construction of aerospace discipline platform and international exchange and cooperation.
