Information on Today's Maneuver
Date/Time(UTC) Message Issued:
12 July 2007, 1600 UTC
Satellite(s) Involved:
MetOp-2/A
Instrument(s) Involved:
All instruments
Product(s) Involved/Affected:
All Products/questionable earth locations
Date/Time(UTC) of Initial Implementation:
12 July 2007, Time 1448 UTC
Details/Specifics of Change:
Eumetsat performed an In-plane maneuver today at 1448 UTC. This should occur in the level 1B pass with the orbit identifier of ...B037778.SV. We expect approximately 17 minutes of data at the end of this pass to be earth located with pre-maneuver data. The following passes beginning with ... B0377879.SV to be earth located using post maneuver data. Since the accuracy of this earth location is uncertain, it will be marked questionable for the first 600 minutes following the maneuver. We plan to monitor the passes and update the earth locations as soon as possible, if needed.
Eumetsat has provided the following information on instruments with operations affected by the maneuver:
