Über ESA Sentinel
The Sentinel App is a gateway to knowing the Sentinel satellites. It lets users track the satellites in real-time, discover their key elements, read the latest news and learn more about their products.
Users can, among other things, explore detailed 3D models of the satellites, see the last and next time they have been and will be over the user's location, move the satellites to the time of the last data transmission and smoothly move them back to their current location over the 3D globe. Notifications can also be set to be warned when the satellites are flying by.
ESA is developing a series of next-generation Earth observation missions, on behalf of the joint ESA/European Commission initiative Copernicus (previously GMES - Global Monitoring for Environment and Security).
The goal of the program is to replace current and older Earth observation missions, such as ERS and Envisat, which have reached or are close to reaching the end of their operational life span. This will ensure a continuity of data so that there are no gaps in ongoing studies.
Each mission will focus on a different aspect of Earth observation, such as Atmospheric, Oceanic or Land monitoring, and the data will be of use in many applications.
