Description
Essaim is a constellation of four 120 kg micro satellites (including one spare) in low earth orbit. They are demonstration models which were supposed to last three years. They fly separated by a few hundreds of kilometers. Missions are designed by the Celar (Centre d'électronique de l'armement) in Bruz, near Rennes and are uploaded from CNES in Toulouse to the constellation. Collected data follows the same path in reverse order.

Famous quotes containing the word description:
“As they are not seen on their way down the streams, it is thought by fishermen that they never return, but waste away and die, clinging to rocks and stumps of trees for an indefinite period; a tragic feature in the scenery of the river bottoms worthy to be remembered with Shakespeare’s description of the sea-floor.”
—Henry David Thoreau (1817–1862)
“To give an accurate description of what has never occurred is not merely the proper occupation of the historian, but the inalienable privilege of any man of parts and culture.”
—Oscar Wilde (1854–1900)
“It is possible—indeed possible even according to the old conception of logic—to give in advance a description of all ‘true’ logical propositions. Hence there can never be surprises in logic.”
—Ludwig Wittgenstein (1889–1951)
