Multi-polarimetric and multi-temporal capabilities
enable many civilian and advanced defence applications. The sensor
can acquire images of the earth in ScanSAR mode (large coverage
with a medium to coarse spatial resolution) or in Stripmap mode
(medium coverage with a fine resolution) or Spotlight mode (small
coverage with metric resolution).
Imaging Capacity
Each satellite can acquire, daily:
- Up to 75 SPOTLIGHT images
- Up to 375 STRIPMAP or 150 SCANSAR images
The complete constellation can acquire a daily total of 1800 images
- 1500 Wide Field
- 300 Narrow Field
- 560 GB/day
Interferometric capability
- One of the best performances of COSMO-SkyMed system is the capability to carry out very accurate measurements based on phase signal (Interferometry) by using indifferently the satellites of the constellation. This guarantees a huge choice in terms of time intervals for change detection and coherence analysis (starting from 1 day intervals) and at the same time provides unprecedented revisit for applications based on the collection of a long time series of images.
Polarmetric products

The system can satisfy a User Request in the case of the first
level of SAR standard products in as little as 72 hours for the
system working in routine mode, 36 hours for the crisis mode and
18 hours for the very urgent mode
Main applications
Maritime Domain Awareness: Maritime awareness (MDA) and Maritime Safety monitoring are supported by frequently collected low spatial resolution ScanSAR modes. Retrieval of information (e.g. ship position, oil slick detection) is carried out in near-real time (less than ½ hour from satellite pass). A fully integrated and automated service chain is implemented at the receiving terminal location (either fixed or mobile).
Defense and Intelligence: The frequent revisit of the constellation, when coupled with the very high resolution (Spotlight mode) opens a completely new area of applications for defense & intelligence. Applications. Very accurate change detection in and around sensitive targets (industrial plants, borders) can be completed with unprecedented time revisit and area coverage. Multi-satellite interferometric configuration allows for coherence analysis (activity maps and disturbed terrain analysis).
Thematic Mapping: The combination of very short term (a few days) change detection and coherence analysis can be used for thematic mapping and environmental monitoring (forestry, agriculture), allowing for large region mapping of areas where collecting optical images is limited by cloud coverage.
Emergency Response: The constellation is a key tool for emergency response activities. The system can rapidly provide information for early damage assessment. In some cases (e.g.: flood mapping) information can be retrieved and provided to users in near-real time.
Land stability analysis: Long term interferometric time series and state of the art processing technology (DIFSAR, Persistent Scatterers analysis) provide information for Land stability analysis such as urban subsidence, infrastructure monitoring – railways and pipeline – landslide and volcano monitoring. The Cosmo SkyMed system can provide accuracy up to few millimetres on intervals as long as months or a year.
