ESA's two European Remote Sensing (ERS) satellites, ERS-1 and –2, were launched into the same orbit in 1991 and 1995 respectively. Their payloads included a synthetic aperture imaging radar, radar altimeter and instruments to measure ocean surface temperature and wind fields.
ERS-2 added an additional sensor for atmospheric ozone monitoring. The two satellites acquired a combined data set extending over two decades.
This application is a gateway to knowing what the mission is about, how it works and what the elements of the space and ground segment that makes this mission unique are.
it includes also a dedicated section that allows one to discover and visualize optical measurements over our planet
Features:
- Description of the ERS missions: space and ground segment
- Large selection of photos and videos on a wide range of topics related to ERS missions
- Striking ERS 3D models with explanations of the different platform and payload elements
- World map with orbit position of the satellite
- Satellite visibility over selected ground stations and local position
- Impressive visualization of ERS measurements over the Earth with vertical profiles and with acquisition strip over the earth
- Access to several geophysical parameters measured by the satellite
…and much more
In the 3D environment:
- swipe/pinch to rotate/zoom the satellite model
- triple touch to reset position
