| Dear ROM SAF GTS User HRPT switching zone drift. The Metop-A satellite is currently in drifting orbit. Pls see the message from Eumetsat below. Issued : 2020-01-30 17:46 UTC Kind regards The ROM SAF Team Type: Planned Maintenance Ann Nr: 5596 Rev: 1 Start Time: 2020-01-29 00:00:00.0 End Time: 2021-12-31 23:59:00.0 Satellites: Metop-A Subsystem: HRPT Subject: general-announcement Impact: risk-of-degradation Detail: HRPT switching zone drift. The Metop-A satellite is currently in drifting orbit. As a consequence the geographical zones, defined to control the switching times of the satellite’s HRPT system, are drifting westwards at a rate of 0.02° 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.
