X-Sat is the name of an earth observation and experimental satellite from the Center for Research in Satellite Technologies in Singapore .

purpose

X-Sat is used to demonstrate CREST's microsatellite technology. The company is a joint venture between Nanyang Technological University and DSO National Laboratories Singapore .

The main tasks of X-Sat are:

  • Earth observation and imaging for environmental applications as well as forest fire and redness monitoring with a 10 meter multispectral resolution instrument (three spectral bands in the visible and near infrared) as the primary payload.
  • Satellite-based data acquisition and distribution and transmission of messages via mobile terminals.

There are also two secondary payloads on board:

  • The Parallel Processing Unit : For experimenting with COTS electronics and FPGAs in order to perform reliable imaging algorithmic functions (image selection, classification, compression) in space.
  • The DLR GPS payload: A GPS receiver made available by the German Aerospace Center for experiments on board.

Start contract

The launch contract between ISRO and NTU for the launch of a satellite with piggy-back function was signed on January 24, 2003.

begin

The launch of X-Sat was made on 20 April 2011, a PSLV - carrier rocket from the Satish Dhawan Space Center along with Resourcesat-2 and Youthsat into a sun-synchronous orbit .
