Aijiang Technology Congratulates StarSource Space on Successful Orbit Insertion of Solar Arrays Aboard BUPT-4 Satellite

On July 22 at 10:54, the Gravity-1 Y4 carrier rocket completed its maiden offshore launch mission over the East China Sea east of Shanghai. Via a "one rocket, nine satellites" launch configuration, it accurately delivered the BUPT-4 satellite (designated TY49), jointly developed by Tianyi Space and Beijing University of Posts and Telecommunications (BUPT), into its predetermined orbit. All satellite subsystems function normally with stable in-orbit operation, marking a full success of the launch mission.

The solar arrays (solar cell panels) independently developed by Beijing StarSource Space Technology Co., Ltd. were officially deployed for in-orbit power supply during this mission, undertaking full-cycle power generation for the entire satellite. This marks the first time StarSource Space’s solar arrays have provided regular full-life on-orbit power for a satellite, representing an engineering leap for its space power systems from experimental flight verification to routine full-satellite power service. Aijiang Technology extends its sincere congratulations on this milestone achievement.

As the exclusive inspection equipment partner for StarSource Space’s triple-junction gallium arsenide solar cells, Aijiang Technology was responsible for factory quality testing of core battery components used in these solar arrays. Leveraging its aerospace-grade precision inspection capabilities, the firm verified multiple critical performance metrics, enforced rigorous quality standards for key components, and guaranteed reliable delivery and stable orbital operation of these high-efficiency power generation assemblies.
