To mitigate the technical risks for selected missions associated with the different sorts of lidar, ESA has undertaken critical technology developments, from the transmitter to the receiver and covering both components and sub-systems development and characterization. Over the last four decades satellites have been radically improving the accuracy of weather forecasts by providing unique and indispensable input data to numerical computation models. In this calculation the spin of the Probe and the asymmetric gain pattern of the transmitting escorts was taken into.
This paper describes the Sentinel-1 missionprovides an overview of the mission requirements, and presents some of the key user driven information products, the crucial requirements for operational sustainable services being continuity of data supply, frequent revisit, geographical coverage and timeliness.

The Sentinel-1 mission is an imaging synthetic aperture radar SAR mission at C-band deed to supply all-weather day-and-night imagery to a of operational Earth observation based services.
The Joliet of the habitability of Jupiter's icy moons is considered of high priority in the roadmaps of the main space agencies, including the decadal survey and esa 's cosmic vision plan. The objective of the Swarm mission is to provide the best-ever survey of the geomagnetic field and its temporal evolution using a constellation of three identical satellites.
Accordingly, ESA maintains long-standing partnerships with other space agencies and relevant institutions worldwide. The Sentinel missions provide accurate, timely, long term and uninterrupted data to provide key information services, improving the way the environment is managed, and helping to mitigate the effects of climate change. These cover applications such as: - monitoring sea ice zones and the arctic environment, - surveillance of marine environment, - monitoring land surface motion risks, - mapping of land surfaces: forest, water and soil, agriculture, - mapping in support of humanitarian aid in crisis situations.
In running its Earth observation programmes, ESA responds to societal needs and challenges as well as to requirements resulting from political priorities, such as the United Nations' Sustainable Development. All of these activities can only be carried out in international cooperation. The setup of the Swarm ground segment and the contents of the data products will be addressed.
