Envisat was launched in 2002 with 10 instruments aboard and at eight tons is the largest civilian earth observation mission.
Esa earth observation satellites.
Weather observation and forecasting goes geostationary operational environmental satellite 17 satellites 2 in operation goes 16.
The aim is to see how satellite data can be used for example to map changes around transport networks commercial ports and heavy industry such as oil refineries.
Envisat was esa s successor to ers.
Polar operational environmental satellites.
The last satellites spot 6 and spot 7 will assure data continuity through to 2024.
Earth observation satellites vary according to the type of orbit they have the payload they carry and from the point of view of imaging instruments the spatial resolution spectral characteristics and swath width of the sensors.
More advanced imaging radar radar altimeter and temperature measuring radiometer instruments extend ers data sets.
The envisat satellite carried an ambitious and innovative payload that ensured the continuity of the data measurements from the ers satellites.
The spot from french satellite pour l observation de la terre constellation has been supplying high resolution wide area optical imagery since 1986.
All of the spot satellites provide imagery in panchromatic and multispectral bands with a swath of 60km.
All these parameters are designed at the beginning of the mission definition depending on the application the satellite mission is targeting.
