Heaviest satellite launched by Cabinet Satellite Intelligence Center (CSIC) into space at 1,600 kg
Designed for earth observation (Optical Imaging), IGS Optical 6 is a government satellite operated by Cabinet Satellite Intelligence Center (CSIC) (Japan).
A sun-synchronous LEO satellite, it was launched into space using H2A as the launch vehicle from Tanegashima Space Center on 26 February 2018. IGS Optical 6 was constructed by Mitsubishi Electric (Japan).
Designated with COSPAR ID 2018-021A and NORAD ID 43223, IGS Optical 6 is designed to operate in space for a lifetime of 5 years. It has a launch mass of 1,600 kg.
Taking 95 minutes to orbit the Earth, the satellite's perigee, which is the point of the orbit closest to the Earth's center of mass, is 485km while its apogee, which is the point of the orbit farthest from the Earth's center of mass, is 499km. The eccentricity of the orbit is 1.02E-03 and it orbits at an inclination of 97 degrees to the equatorial plane of the Earth.
Heaviest satellite launched by Japan into space at 5,857 kg
A commercial satellite, JCSat 17 is operated by Sky Perfect JSAT Corporation of Japan for the purpose of communications.
Constructed by Lockheed Martin Commercial Space Systems (USA), it was launched into space using Ariane 5 as the launch vehicle from Guiana Space Center on 18 February 2020. JCSat 17 orbits around the Earth as a GEO satellite.
Designated with COSPAR ID 2020-013A and NORAD ID 45245, JCSat 17 is designed to operate in space for a lifetime of 15 years. It has a launch mass of 5,857 kg.
With an orbital eccentricity of 3.20E-04, the satellite's perigee, which is the point of the orbit closest to the Earth's center of mass, is 35,773km while its apogee, which is the point of the orbit farthest from the Earth's center of mass, is 35,800km. It takes 1,436 minutes to orbit the Earth.
JCSat 17 orbits along the longitude of 136 degrees at an inclination of 7 degrees.
Operated by University of Tokyo and NESTRA of Japan, Hodoyoshi-3 is a government satellite launched for the purpose of technology development.
A sun-synchronous LEO satellite, it was launched into space using Dnepr as the launch vehicle from Dombarovsky Air Base on 19 June 2014. Hodoyoshi-3 was constructed by University of Tokyo (Japan).
Hodoyoshi-3 has a launch mass of 60 kg and orbits around the Earth with the COSPAR ID 2014-033F and NORAD ID 40015.
With an orbital eccentricity of 3.78E-03, the satellite's perigee, which is the point of the orbit closest to the Earth's center of mass, is 613km while its apogee, which is the point of the orbit farthest from the Earth's center of mass, is 666km. It takes 98 minutes to orbit the Earth.
With generated usable power of 50 watts, Hodoyoshi-3 orbits at an inclination of 98 degrees to the equatorial plane of the Earth.
