Abstract

VEGETATION is one payload on the earth-observation satellite SPOT 4, launch-scheduled in 1992. It is developed, assembled and tested by AEROSPATIALE, under CNES contract. [ts objectives are : - primarily : an operational world-scale survey of the evolution of vegetation (forecasting of agricultural yields and environmental studies). - secondarily : the observation of oceanic areas. Field of view is ± 50,5°C (2000 km on ground), with observation frequency of less than 2 days at equator. The system, equipped with its own telemetry channels and on-board computers, will send coded data according 2 types of observation : - world wide observation : recording, then time-tagged transmission, with a nadir resolution of 1,165km x 1,165 km or (in an exclusive sense)4,66 km x 4,66km (agglomeration of 16 pixels). - regional observation real-time transmission, with a nadir resolution of 1,165km.
