Dr. Peerapong Torteeka, President’s International Fellowship Initiative (PIFI) visiting scientist, conducted an online academic exchange with researchers of the Changchun Institute of Optics, Fine Mechanics and Physics (CIOMP) on July 14.

Dr. Torteeka, engineer of the National Astronomical Observatories of Thailand, leads a team of Thai researchers working on the TSC-Pathfinder, a high-precision optical satellite jointly developed by CIOMP and the National Astronomical Observatories of Thailand.

A CAS alumni majoring in celestial Mechanics and astrometry Engineering, Dr. Torteeka’s current research interests include sensor fusion processing technology, nonlinear parameter estimation and control system engineering.

As a PIFI scientist, he worked in the team of Dr. Xu Wei, Director of the CIOMP Space New Technology Department, between 2022 and 2023 on the Sino-Thailand joint satellite attitude control and component development. Following progress of the project, Dr. Torteeka has returned to Thailand to work with the Thai team.

Dr. Torteeka’s report, "Research on Spacecraft Trajectory Optimization Technology and Its Applications", was a summary of his research work at CIOMP. It systematically introduced the historical background and evolution of spacecraft orbit optimization technology, the theoretical basis of the system, as well as the current research methods and tools, introduced the application methods and key results of swarm UAV algorithm in spacecraft attitude control, and expounded further technical improvement research.

Dr Torteeka talked about his work as a PIFI scholar. It was concluded that as an important part of China’s international academic exchange efforts, PIFI can inspire the participants' scientific research ideas and improves their academic appreciation ability. It is hoped that continuous cooperation in the future will enable both parties to achieve research breakthroughs and improve the international standing of CIOMP.
