Special Acquisition Planning

30 January 1996

The following acquisitions, for both ERS-1 and ERS-2, will be planned over the flooded area in southern France (29 Jan. 1996).

ATSR unavailable

23 January 1996

The Along Track Scanning Radiometer (ATSR-2) which was working remarkably well since launch, ceased normal operations on 22 December 1995 because of a problem with the scanning mirror. A team at the Central Laboratories of the Research Council (CLRC) in the United Kingdom, which developed and funded this UK-provided instrument, is investigating the reasons for the anomaly. CLRS has agreed to keep the media informed of progress in the investigation and of the efforts made to resume the instrument's normal operations.

ERS-2 and ERS-1 flying in tandem

23 January 1996

Since 16 August 1995 and until mid-May 1996, ERS-1 and ERS-2 are being operated simultaneously. This is the first time ever that 2 identical SARs are operating in tandem. The orbits of the two satellites are carefully phased to provide a 1-day revisit interval; this enables collection of (interferometric) SAR image pairs which will be used for the generation of a global Digital Terrain Model (DTMs) set as well as for many other novel applications such as differential interferometry. In this context, ESA has just released an Announcement of Opportunity to the scientific-academic community to evaluate the potential of SAR interferometry (INSAR) and differential INSAR for geo-hazard risk assessment arising from earthquakes, volcanic erruptions, landslides and glacial surges.

ERS-2 instruments

23 January 1996

The radar altimeter and its supporting microwave sounder are fully operational and the new GOME instrument is already producing data of exceptional interest, thus promising to be the best ozone monitoring instrument currently in orbit.

ERS-2 will track down the origins of ozone depletion

23 January 1996

The first scientifically meaningful results derived from the Global Ozone Monitoring Experiment (GOME) onboard its ERS-2 satellite.

PRARE available

23 January 1996

The PRARE entered its operational phase on 1 January 1996 and the PRARE ground station network is being progressively completed. The instrument is fully compliant with its specified performances.

ATSR unavailable

19 January 1996

ATSR-2 remains unavailable.

Yearly ERS manoeuvre history

29 December 1995

ERS manoeuvre history for 1995 is available at ESOC'sNear-Earth Navigation and Geodesy site.

ATSR unavailable

22 December 1995

ATSR switch down due to a scan temperature out of limit.
