Satellite Programme: Sentinel-1
Programme details
Programme description
Two-satellite programme to provide operational continuity to the Envisat ASAR.
ESA programme co-sponsored by the European Commission in the context of the Copernicus programme (formerly: GMES, Global Monitoring for Environment and Security). ESA responsible of development and operations.
The platforms are actively stabilised over 3 axes.
The design life time is 7.25 years.
The satellites are launched at a short time interval in order to fly in constellation for larger swath, interferometry and redundancy. Dawn-dusk orbit at 6:00. 180° dephasing between the two satellites.

Data circulation
The global data are downlinked in real-time to a network of ground stations and, when ready, the European Data Relay Satellite system (EDRS).
Selected data (limited areas or low-resolution mode) can be stored onboard.
Data are processed at the Payload Data Ground Segment (PDGS), a distributed system common to other Sentinel satellites of the GMES framework.
