Orbit and Launcher

BRITE-AUSTRIA (TUGSAT-1) and UniBRITE will be launched by the Indian Space Research Organization (ISRO) from Sriharikota, near Cheney in India. The launch campaign is scheduled for March/April 2012. A Sun-Synchrounous Polar Dawn-Dusk Low Earth Orbit (LEO) with a height of about 800km was selected.

With such an injection into space the satellites trajectory will occur above the night-daylight line (terminator) of the Earth. One of ISRO’s rocket series is called Polar Satellite Launch Vehicle (PSLV) of which 17 have been launched thus far with a very high level of success. BRITE-AUSTRIA (TUGSAT-1) and UniBRITE will be part of the same PSLV launch campaign.

The launch services for the Polish and Canadian BRITE satellites remain to be negociated. Alternative launch services and different orbit parameters are in discussion, driven partly by financial and schedule considerations
