Subsystem: | HRPT
Subject: | general-announcement
Impact: | data-unavailable
Detail: | HRPT switching zone drift. Risk of interruption. The Metop-A satellite is currently in drifting orbit. As a consequence the geographical zones, defined to control the switching times of the satellite HRPT system, are drifting westwards at a rate of 0.02 degree per day. Users near the borders of switching zones might experience small changes in their acquisition times of the HRPT signal. On-board timings will be updated approximately every 8 months to compensate for the drift geolocation. A dedicated announcement will be issued in advance of each of these updates.

Detail: | Software Release of GRAS PPF. Changes to the GRAS Level 1 product algorithms. The algorithm changes include technical improvements and bug fixes, as well as support to the changed data formats of the auxiliary files provided by the Radio Occultation Support Network (RSN). This message refers to the second phase of the deployment which will use the changed RSN auxiliary files (after a first phase planned to take place on 04 February 2020). [Rev. 2] The second phase of the deployment will no longer take place on 12 February 2020, it is postponed to a future date. [Rev. 3] The second phase of the deployment using the changed RSN auxiliary files is further postponed to 7th April 2020. [Rev 4]: The deployment is postponed to a future date.
