- Abstract
With the aim to provide more performing and affordable space systems, the CNES and EADS Astrium have developed in partnership the Myriade multimission platform. This flexible vehicle has been extensively used within EADS Astrium to support the development of many 100 Kg satellite systems based on AstroSat 100, in-house declination of the original Myriade development. Six satellites based on AstroSat 100 have been already launched and are performing extremely well in orbit, four of them being currently under extended operation phase. Up to now, the AstroSat 100 bus has been used for 13 satellites under EADS Astrium prime-contractor ship, 7 satellites being in development for French MoD as well as for several export customers such as Algeria and Chile. This extensive utilization makes of the AstroSat100 product line a true success story. Among the latest EADS Astrium successes are certainly the contracts award of both the Algerian Alsat-2A/2B satellites and the Chilean SSOT satellite. These successes have been made possible thanks to both AstroSat 100 flight proven bus (cumulating more than 25 years in-orbit operation) together with NAOMI Earth observation optical payload. based on the breakthrough SiC technology developed by Astrium. The next launch of an AstroSat 100/NAOMI high resolution satellite (Alsat-2A) is scheduled mid-2009 on PSLV Indian launcher. The satellite, entirely designed and developed within EADS Toulouse premises will bring to Algeria high quality pictures with a 2.5m resolution in panchromatic mode and a 10m resolution in four bands multispectral mode. More recently, an enhanced configuration allowed EADS Astrium to propose to Chile a cost effective high resolution system with a panchromatic resolution of 1.45m and multispectral resolution of 5.8 m (4 bands). This version is planned to be launched in the first quarter of 2010. These outstanding performances within a 115 Kg launch mass set a new standard for high resolution Earth observation small satellites. The paper describes the Astrosat 100 product line and the latest achievements in term of high resolution optical Earth observation satellite applications developed for Algeria and Chile.
