态度确定和控制系统（ADC）被认为是航天器中最关键的子系统之一，必须仔细校准和监视，以确保许多新兴的小卫星任务具有大型的众多星座。目前，可以容纳许多ADC子系统的管理方法。自2013年首次发布以来，地球观察只有一小部分ADC工程师和卫星运营商负责整个星座的性能。在当今的大小旨在最大程度地减少对人类的需求，但是在需要的情况下，它们旨在使敏捷的决策能够分享从校准和监视ADCS子系统的启用。
The Attitude Determination and Control System (ADCS) is considered one of the most critical subsystems of a spacecraft, and must be carefully calibrated and monitored to ensure mission success. Many emerging small satellite missions feature large constellations, creating a need for new design philosophies and operational approaches to accommodate the management of many ADCS subsystems simultaneously. Planet currently operates approximately 190 Dove Cubesats for Earth Observation, with only a small team of ADCS engineers and satellite operators responsible for the performance of the entire constellation. Since Planet’s first launches in 2013, on-orbit data and diverse experiences have contributed to the evolution of techniques and tools to support a fleet of this size. Today, Planet’s ADCS engineers and operators rely on automated systems to enable on-orbit calibration, nominal operations, performance monitoring, and anomaly detection. The systems are intended to minimize the need for humans-in-the-loop, but where it is required they are designed to enable agile decision making. This paper shares techniques, insights and lessons learned from calibrating and monitoring ADCS subsystems at scale.
