On the 24th of March 2009, The Cabinet passed a resolution granting NARIT permission to proceed with plans to construct a Regional Observatory for the Public in each of the following five provinces: Nakhon Ratchasima, Chachoengsao, Songkhla, Khon Kaen, and Phitsanulok. 

As of 2024,four of these locations have been opened to the public—Nakhon Ratchasima, Chachoengsao, Songkhla and Khon Kaen. The other in Phitsanulok, are currently under construction. 

All five observatories in this project are under the royal patronage of Her Royal Highness Princess Maha Chakri Sirindhorn, who generously bestowed upon each the name “Regional Observatory for the Public in Honor of the King’s 7th Cycle Birthday” followed by the name of the province in which it is located.
