Abstract	The design and test results of the attitude and orbit control system (AOCS) of the small satellite TET 1 as an example of a cost effective but still robust and reliable AOCS platform for small satellites is presented in this paper. The AOCS of TET-1 is fully three-axis stabilized while particular attention is paid to the implementation of robust and fault tolerant design. The redundancy management concept and robust control algorithms are presented. Furthermore the fault detection, isolation and recovery (FDIR) mechanism, which are implemented in various functional levels, are shown. Finally the paper presents the test strategy and results for verifying the proposed fault tolerant design.
