SAOCOM SYSTEM OVERVIEW• Mission Main Drivers :

• Soil Moisture

• agriculture, fishing and forestry,

• weather and climate, hydrology and oceanography,

• emergencies,

• environment and natural resources of land and sea,

• urban areas, cartography, geology, mining and territorial planning,

• Health

• 2 satellites carryingL‐Band (1,275GHz) SAR Instruments

• Launch datesSAOCOM‐1A: 07‐October‐2018SAOCOM‐1B: Q1 2020



“QP” swaths can be acquired in quad polarization “DP” swaths can be acquired in dual polarization (either HH‐HV or VH‐VV) or single polarization (either

HH or VV) TWCP can be acquired in Compact polarization with reduced duty cycle 63 Science data acquisition modalities
