On May 10, two TY-SPACE PST3S-K4 star trackers embarked on a space journey on Tianzhou-6 with the “Dalian-1(LIANLI) satellite”. This time, the PST3S-K4 star tracker will provide on-orbit attitude determination service for the “Lianli” satellite. The 12U ultra-light and ultra-small multi-spectral remote sensing satellite has a mass of only 17kg, and the main load is a high-resolution multi-spectral camera. It was designed and developed by the Dalian University of Technology. Its main on-orbit task is to verify high-resolution remote sensing imaging. The domestically produced high-reliability OpenHarmony operating system, and a series of innovative technologies such as advanced satellite components and ultra-light deployers based on 3D printing technology.
TY-SPACE PST3S-K4 star tracker realizes the in-orbit deployment of the hood through the pop-up design, the installation height is only 35mm, lightweight, small volume, and envelope, and is professionally used in ultra-small space vehicles such as micro-nano satellites and cube stars.
