VNREDSat-1 was launched into space on May 7, 2013, making Vietnam one of the 25 countries in the world that satellite observe the earth separately at that time. The satellite is responsible for providing high-resolution data images to serve the management and monitoring of natural resources, the environment, disaster prevention…
Designed to operate for about 5 years, but VNREDSat-1 works beyond design time. Therefore, according to the Institute of Space Technology, from the end of 2021 (after more than 8 years of operation), the satellite encountered a serious technical error related to the hardware of the operating and control data storage system. This technical error exceeds the self-healing ability, causing the system to temporarily stop operating and exploiting from November 9, 2021 to March 25, 2022.
Vietnamese experts assess that the system can continue to be exploited well in the near future. French experts (where the satellite is manufactured) also said that, after nearly 9 years of operation, the images obtained by VNREDSat-1 satellite still ensure quality and efficiency for use in economic development applications. society, ensuring national defense and security.
Instead of working with a satellite manufacturer, which costs a lot of money and time, the staff at the Center for Control and Operation of Small Satellites, the Institute of Space Technology, and Vietnamese experts have restored completely restore the system control servers and bring back the VNREDSat-1 satellite to take pictures.
