The satellite reached its final orbit on 3rd April and is since then positioned on its assigned 35 days repeat cycle, 30 minutes ahead of ERS-2; both satellite being controlled to overfly the same ground track, within ý1 Km. Following the successful completion of the satellite and instrument activation, the SODAP Review (Switch On and Data Acquisition Phase) was held 17 April at ESOC, Darmstadt, Germany. All instruments were fully activated by mid April, except SCIAMACHY for which, the Elevation Scanning Mirror cover was opened by mid June.
The calibration activities have been initiated right after the instrument activations, with round orbit data recorded on board and dumped over the PDS Kiruna (Sweden) station as well as real time ASAR and MERIS data received at the Matera (Italy) station. This scenario permits to recover the full global mission data.
All instrument modes have been tried out and very stable performances have been observed with all of them. Most of the instrument processors, installed in the Payload Data Segment, have been already updated to reflect the specific characteristics observed early on in orbit and to prepare for the product release, which will follow the calibration review.

First (out of four) ASAR panel deployment completed successfully at 03h30 AM. The other 3 deployments will be performed on Sunday and Monday.

Envisat altitude raised by 3.5 km, to let it drift until it reaches its planned position 30 minutes ahead ERS-2. The drift phase will take 33 days to complete, after which Envisat altitude will be lowered again.

Each Payload Data Segment (PDS) facility has been upgraded by the PDS prime and subcontractors to version 3, making them compatible with the on board Solid State recorder, the latest satellite to Ground interface, and the latest version of computer platform hardware and operating system.

Over the last two weeks the Envisat flight model went successfully through all mechanical vibration tests at ESTEC. The test results have convinced Arianespace that Envisat is now qualified to the Ariane 5 launch environment. The successful completion of these tests, during the end of August, was not only a milestone for the Envisat project, but also for the large hydraulic shaker Hydra, as Envisat was its first customer. Hydra is the biggest satellite shaker in Europe and the newest facility facility at ESA's test centre at ESTEC.
