What is ERS?
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.
Latest Mission Operations News
Due to a scheduled maintenance on the OTF infrastructure, access to the ERS and Envisat (A)SAR data collections on the Simple Online Catalogue (SO-Cat) dissemination tool will be unavailable on Thursday 29 August 2019 from 09:00 to 11:30 CEST.
The Precise Orbit files (ERS.ORB.POD) for the entire ERS-1 and ERS-2 mission periods have been reprocessed with up-to-date standards and is now available to users on the ESA dissemination server upon fast registration.
A software maintenance affecting the On-The-Fly (OTF) Third Party Missions (TPM) and ERS / Envisat (A)SAR data dissemination services has been planned for Wednesday.

Using a 25-year record of ESA satellite data, recent research shows that the pace at which Greenland is losing ice is getting faster.
03 December 2014
Lovers of architecture and history can rest easy: the stability of historical buildings can now be monitored in real time by a new technique with its roots in space.

Twenty years of radar coverage from ESA satellites have been used to measure the rapid thinning of Antarctica's Pine Island Glacier - and it's losing more ice than previously thought.
14 March 2012
An ESA-funded project to model sea ice dynamics using archived radar data from the Envisat and ERS missions has released its first validated datasets for the Arctic winters of 2004-11. Mapping sea ice displacement is key for climate research.

Watch the celebration and scientific workshop on the legacy of the two ERS satellite missions. The events were held on 27 September at ESRIN, ESA's centre for Earth observation, in Frascati, Italy.
13 July 2011
These images of Rome and its surroundings were acquired by ERS-1 and ERS-2 during their long service around the globe, providing valuable information to the scientific community for 20 years.
29 April 2009
Envisat and ERS-2, ESA's two veteran Earth missions, have completed a second tandem observation campaign. The technique involved flying the two satellites in precisely coordinated orbits, generating valuable new radar data for modelling Arctic terrain.
