Metop-A was the first satellite subject to an agreement between the United States and Europe that placed NOAA-provided instruments on a European satellite operated by EUMETSAT.
The deep-space scanning maneuver on Metop-A acquired data intended to improve calibration and provide a new baseline for data processing applicable retrospectively to all Metop data.
Metop-A was launched in 2006 on a Soyuz rocket from Kazakhstan.
Metop-C will operate in the same 817-kilometer sun-synchronous orbit with a mid-morning crossing time as Metop-A and Metop-B.
