All the satellites have been successfully put into orbit around at an altitude of 550 km. After that the rocket's fourth stage will be shut down.
Around 46 minutes after the launch of the sixth satellite, the fourth stage will be restarted when it is in a lower altitude of 523.9 km.
The engine will be in operational for four seconds and would go up to an altitude of 524 km before the stage is cut-off.

The PSLV rocket is a four stage/engine rocket powered by solid and liquid fuel alternatively.
Out of the six satellites, the 400 kg earth observation satellite called TeLEOS-1 is the main passenger for the PSLV rocket and hence the mission is called TeLEOS mission by ISRO.
TeLEOS-1 is Singapore's first commercial earth observation satellite designed and developed by ST Electronics.
The other five co-passenger satellites are VELOX-C1 (123 kg), VELOX-II (13 kg), Kent Ridge-1 (78 kg), Galassia (3.4 kg) and Athenoxat-1.
These satellites would help the city-state gather information on disaster monitoring and urban planning.
Today's mission is last rocket launch mission for ISRO in 2015.
