TY 16 (Tianyi 16) and TY 17 (Tianyi 17) are a pair of commercial earth obseervation nanosatellites developed by Spacety Aerospace Co. at the Changsha Gaoxinqu Tianyi Research Institute, Hunan.
These are medium-resolution remote sensing satellites to carry out satellite data applications such as disaster emergency monitoring, marine maritime applications, agricultural remote sensing services, polar environmental monitoring.
The satellites were built to the 6U CubeSat form factor.
Both were orbited together on a multi-satellite launch on a Kuaizhou-1A rocket in December 2019.
