BRITE-Constellation is an ongoing space mission carrying out two-band photometry in wide fields with a constellation of six (presently, three operational) BRIght Target Explorer (BRITE) nanosatellites.

In March 2005 a program for improving the infrastructure of Austrian Universities was established by the Austrian Ministry of Science and Technology, to which the University of Vienna submitted a proposal for UniBRITE (PI: Werner W. Weiss), which was accepted in October 2005 and UniBRITE was ordered at SFL.

Following an initiative by Slavek Rucinski, Aleksander Schwarzenberg-Czerny (CAMK) was able to obtain funding for two Polish BRITE satellites at the end of 2009.

Following that, the Canadian Space Agency (CSA) finally funded BRITE-Toronto and BRITE-Montréal (PI: Anthony Moffat, University of Montréal) in 2011.

Due to problems with the attitude control system (ACS), observations with UniBRITE were suspended in August 2019, more than six years after its launch.
