What is "x-sat"

X-Sat is a microsatellite developed and built by the Nanyang Technological University (NTU) in collaboration with Defence Science Organisation (DSO) Singapore. The satellite was launched by ISRO's PSLV-C16 on 20 April 2011 from Satish Dhawan Space Centre FLP in Sriharikota, India. The satellite was launched along with Indian ResourceSat-2 and Indo-Russian YouthSat.

The objective of the X-SAT mission is to demonstrate technology in support of high-resolution imaging capabilities and to analyse and implement onboard parallel-processing algorithms, thereby demonstrating improved mission achievements for generally downlink-limited small satellite imaging missions.
