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: | During the indicated period, the GRAS receiver onboard Metop-A will undergo a series of tracking parameter tests aiming at extending the measurements in the ionosphere. During this period, the number of daily occultations from Metop-A as well as the penetration of rising occultations into the mid and lower troposphere might vary more than usual. Periodic outages of 1 orbit will be possible due to patch uplink to the instrument. [Rev. 2] Updated list of affected services. [Rev. 3] End date updated.
