Latest Patents
One of Bender's latest patents is the "Sun-referenced safe-hold control for momentum biased satellites." This system employs a safe-hold processor that responds to sun sensors to detect attitude errors of solar wings. The processor provides independent control logic to rotate the solar wings, ensuring sunlight is maintained on them to sustain solar power in safe-hold mode. Additionally, it controls the momentum wheel to achieve a passively stable nutational state, enhancing spacecraft health through active control of solar wings.
Another notable patent is the "Spacecraft acquisition of sun pointing." This system and method enable a three-axis stabilized spacecraft to acquire sun pointing by slewing solar wings until the sun is detected. It determines an initial sun vector and performs rotations to align the instantaneous sun vector with a preferred final sun vector. The method optimizes the time required for achieving the desired thermal attitude and maintaining Earth lock.
