YUsend-QB50 (QB50 CA01)

YUsend-QB50 is a 2U-CubeSat for technology development and upper atmosphere science. It is developed and built at the York University, Toronto.

YUsend-QB50 will be one of the satellites in the QB50 constellation of CubeSats being coordinated by the Von Karman Institute. The spacecraft will carry the FIDEX QB50 instruments as well as elements developed and tested in the YUsend lab in the Centre for Earth and Space Science (CRESS). Proposing an UHF 9k6 AFSK transceiver. The spacecraft will also carry a GAMANET radio.

It is a part of the QB50 constellation to gather science data in the upper layers of the troposphere in the altitude range from 350 km down to 200 km. The QB50 project, which demonstrates the possibility of launching a network of 50 CubeSats built by Universities Teams all over the world to perform first-class science in the largely unexplored lower thermosphere.

It carries the FIPEX (Flux-Φ-Probe Experiment) of TU Dresden as the primary payload for the QB50 project, which is able to distinguish and measure the time-resolved behaviour of atomic and molecular oxygen as a key parameter of the lower thermosphere.

The satellite was to be launched with the bulk of the QB50 constellation to the ISS in 2017, from where they will be deployed. The in-orbit lifetime of YUsend-QB50 was to about 3 months, from deployment to de-orbit. YUsend-QB50 was not completed in time for launch.
