Objectives and Applications
The primary mission of H3 and H4 is Earth observation by using various optical sensors. H3 has two different cameras which are low- and mid-resolution with a GSD (Ground Sampling Distance) of 250 m and 40 m; on the other hand, H4 has one relatively high-resolution camera with a GSD of 6-10 m. Furthermore, the satellites have various secondary mission instruments, for example, wide-angle mini cameras, hosted payload boxes, technology demonstration module and materials, UHF data receiving system for a Store and Forward mission, in order to provide opportunities for rapid new technology demonstration on orbit and low-cost commercial usage like advertisement in space.
