Solar and Anomalous Cosmic Rays in the Magnetosphere - Orcas Experiment on Board the Brazilian Satellite Saci-l

A satellite experiment "Observacoes de Raios Cósmicos Anomalos e Solares na Magnetósfera - ORCAS" is being developed to monitor the charged particle environment in the inner magnetosphere and will be deployed on board the Brazilian micro-satellite SACI-l in 1998. The satellite's minimum life time of 18 months is expected to span both quiet and active periods of solar activity and defines the scientific objectives. The satellite will orbit at - 700 Km in sun synchronous mode and spins at - 10 RPM. This experiment is a collaborative effort of scientists working at INPE and UNICAMP of Brazil, RIKEN and University of Tamagawa (UT) of Japan and Naval Research Laboratory (NRL) of USA.
