TUGSAT-1 was manufactured by the University of Toronto based on the Generic Nanosatellite Bus, and had a mass at launch of 7 kg (plus another 7 kg for the XPOD separation system). The spacecraft is cube-shaped, with each side measuring 20 cm. The satellite will be used, along with five other spacecraft, to conduct photometric observations of stars with apparent magnitude of greater than 4.0 as seen from Earth. TUGSAT-1 was one of the first two BRITE satellites to be launched, along with the Austro-Canadian UniBRITE-1 spacecraft. Four more satellites, two Canadian and two Polish, were launched at later dates.

The TUGSAT-1 spacecraft was launched through the University of Toronto's Nanosatellite Launch System programme, as part of the NLS-8 launch, along with UniBRITE-1 and AAUSAT3. The NLS-8 launch was subcontracted to the Indian Space Research Organisation (ISRO), who placed the satellites into orbit using a Polar Satellite Launch Vehicle (PSLV) in the PSLV-CA configuration, flying from the First Launch Pad at the Satish Dhawan Space Centre. The NLS spacecraft were secondary payloads on the rocket, whose primary mission was to deploy the Franco-Indian SARAL ocean research satellite. Canada's Sapphire and NEOSSat-1 spacecraft, and the United Kingdom's STRaND-1, were also carried by the same rocket under separate launch contracts. The launch took place at 12:31 UTC on 25 February 2013, and the rocket deployed all of its payloads successfully.
