Verification and validation testing for the parker solar probe guidance and control system

Parker Solar Probe was launched on a 7-year mission to explore the Sun in August 2018. A successful first orbit was preceded and enabled by a rigorous test campaign prior to launch. This paper discusses two of the main portions of that test program used to characterize and verify the performance of the spacecraft’s guidance and control system. An extensive set of stand-alone simulations was designed to demonstrate compliance with performance requirements and explore system behavior in response to a large set of fault c ...

Initial attitude control challenges for the solar probe plus spacecraft

The Solar Probe Plus (SPP) mission plans to launch a spacecraft to explore the Sun in 2018. Attitude control is maintained with a 3-axis stabilized, closed-loop control system. One of the first tasks for this system is acquiring attitude knowledge and establishing attitude control after separation from the launch vehicle. Once control is established, the spacecraft must be moved through a sequence of attitudes to meet power and thermal constraints and reach a powerpositive state. This paper describes the options selected for ...

Sun direction determination for the solar probe plus spacecraft

The Solar Probe Plus (SPP) mission plans to launch a spacecraft to explore the Sun in 2018. This paper presents the process applied in the attitude control flight software for the spacecraft to determine the best Sun direction from Sun sensor data or a vector derived from on-board ephemeris models and the estimated attitude. Self-consistency checks applied to determine validity of these different knowledge sources are explained, with emphasis on processing of solar limb sensor data. Consistency checks between the available d ...
