CBERS-4 (China Brazil Earth Resources Satellite - 4, also known as ZY-01-4 or ZY-1 FM4) is a joint Brazil-China land-resource and environmental monitoring satellite launched on 2014-12-07.[1][2] It flies a sun-synchronous orbit at approximately 778 km altitude with a 10:30 local solar time.[3] The satellite carries five instruments: MUXCAM, PANMUX, WFI-2, IRMSS-2, and a Data Collection System (DCS).[2] CEOS records CBERS-4 as operational extended with EOL December 2025, while WMO OSCAR recorded it as operational with EOL at least 2026 as of a 2026 update.[2][3] Applications include land-cover change monitoring, deforestation tracking, inland water mapping, and agricultural land analysis; the Brazil Data Cube ingests CBERS-4 imagery as input data for national-scale time-series analysis.[4] INPE operates the mission; CRESDA is the Chinese co-lead agency.[2]
