Satellite developed by the Chinese Academy of Sciences (CAS) for pursuing sustainable development. It is expected to provide advanced, open and shared data resources for monitoring and evaluating the sustainable development index representing the interaction between human and nature, in particular providing support for Sustainable Development Goals (SDGs) of the UN 2030 Agenda for Sustainable Development. The satellite has three payloads including thermal infrared, low light level and multispectral imagers, with 300 km wide data acquisition swath capability. It can achieve global coverage within 11 days.
Sun-Synchronous OrbitThe Quasi-Zenith Satellite System (QZSS) is a three-satellite regional time transfer system and the satellite-based augmentation system for the GPS that would be receivable within Japan. The primary purpose of QZSS is to increase the availability of GPS in Japan's numerous urban canyons, where only satellites at very high elevation can be seen. A secondary function is performance enhancement, increasing the accuracy and reliability of GPS derived navigation solutions. QZS-1R is a replacement satellite for QZS-1 which was launched in 2010.
