A Pre-Processed Orbital Parameters Approach for Improving Cubesat Orbit Propagator and Attitude Determination
2016
Transactions of the Japan Society for Aeronautical and Space Sciences
Nanyang Technological University has built and successfully launched the VELOX-PII and VELOX-I cubesats. Both of the satellites carry a low-power consumption in-house-developed attitude determination and control subsystem (ADCS). The ADCS uses an 8-bit microcontroller. However, in-orbit propagation data indicates that the ADCS suffers high orbit propagation error due to the finite word length of the processor. High orbit propagation error could lead to a higher attitude determination error that
