Chinese startup Spacety released the first images from Hisea-1, a C-band Synthetic Aperture Radar (SAR) satellite, launched Dec. 22 on China’s new Long March 8 medium-lift rocket.
Three days after launch, Spacety began receiving data from Hisea-1’s SAR payload built by the China Electronics Technology Group. On Dec. 27, Spacety acquired its first batch of SAR imagery including a three-meter-resolution image of Tennessee published in a Dec. 30 news release.
“This is the world’s first miniatured C-band SAR satellite, and also the first commercial SAR in China,” James Zheng, Spacety Luxembourg CEO, told SpaceNews by email.
In recent years, several companies have raised money to build and launch constellations of small SAR satellites. Two have succeeded so far.
Finland’s Iceye operates five X-band SAR satellites. San Francisco-based Capella Space began releasing imagery in October from its first operational satellite, Sequoia, which also operates in X-band.
Spacety plans to build, launch and operate a constellation of 56 small SAR satellites.
