GF -1 and GF-2
GF -1 include 4 identical satellites. It mainly applies in land resource investigation, mineral resource management, atmospheric and water environment quality monitoring and natural disaster emergency response and monitoring. GF-2 is a follow-on mission of the GF-1. It provides high accuracy, geographical mapping, land and resource surveying, environment change monitoring, etc.
