Meteosat 7

 1997-049B


Eumetsat/Darmstadt's Meteostat Transition Programme Satellite (MTP, or Meteosat 7) uses the same design as MOP. It is built by Aerospatiale/Cannes and has a launch mass of 689 kg, BOL 490 kg, dry 316 kg. The satellite is a cylinder 2.10m diameter and 3.06m high, spin stabilized.

Radiometer cover ejection gave dV of 0.023 m/s; if radiometer cover is 1 kg, conservation of momentum says it gets an 11 m/s dV and could change its orbit by a few hundred km.

Launch by Ariane in 1997 Sep 2. The satellite was moved to cover the Indian Ocean in 2006 for the IODC (Indian Ocean Data Coverage) mission previously handled by Meteosat-5 and 6. It will be retired in 2017.
