Associated space launch
IRS-P4 (Indian Remote Sensing Satellite) or Oceansat is the first indian satellite primarily built for Ocean applications. Kitsat (Korean Institute of Technology Satellite 3), renamed on orbit as Uribyol 3, was the first Korean satellite in true sense and was launched by an Indian PSLV-G (2) rocket in May 1999.
IRS P4 (OCEANSAT 1) was lifted into orbit during the mission ‘PSLV | IRS-P4 & Uribyol-3’, on board a PSLV space rocket.
The launch took place on May 26, 1999, 6:22 a.m. from Satish Dhawan Space Centre First Launch Pad.
