CAST 2000 Satellite Platform

CAST 2000����ƽ̨ Overview

CAST2000 is a compact satellite platform characterized by its high performance, expandability and flexibility. It is fitted with an S-band TT&C sub-system, X-band data transmission sub-system and 3-axis attitude stabilization, and is able to offer highly precise control, large-range sway maneuver, flexible orbit maneuver, highly integrated housekeeping and highly effective power supply.

This platform has already been successfully applied in several Chinese small satellites, including the OceanSat-1A, 1B and Huanjing-A, B satellites, and its performance and reliability have proven to be excellent.
