Attitude and position determination using a star mapper on thesmall-satellite platform PoSAT-1,

摘要

Abstract: On September 1, 1993 Portugal had its first small satellite called PoSAT-1 launched on the Arianespace Ariane 4 launcher from Kourou, French Guiana, and placed into an 820 Km polar and sunsynchronous orbit. This launch culminates nearly 18 months work, including the projection of an experimental low cost star mapper in this satellite category. This paper describes an overall view of the system concept, where special efforts were dedicated in the use of commercially available components in compliance with typical constraints for small satellites. !6
