The ground segment for the ESA M4 Ariel exoplanet space mission is introduced. The ground segment encompasses the framework necessary to support the development of the Ariel mission to launch, in-flight operations and calibration, data processing pipeline and data handling, including user support. The structure of the ground segment and assumed responsibilities between ESA and the Ariel mission consortium is explained, along with their interfaces. The operational phases for the mission are introduced, including the early commissioning/verification phases, the science operations and the calibration strategy. The smooth transition of the ground segment through the various pre/post launch mission phases to nominal operations will be paramount in guaranteeing the success, scientific return and impact of the Ariel mission. The expected science data products are defined and a representative data processing pipeline is presented.

介绍了ESA M4艾里尔系外行星太空任务的地面部分。地面部分包括支持Ariel任务发展所需的框架，该任务包括发射，飞行中的操作和校准，数据处理管道和数据处理，包括用户支持。ESA和Ariel之间地面部分的结构和承担的责任解释了任务联盟及其接口。介绍了任务的操作阶段，包括早期的调试/验证阶段，科学操作和校准策略。地面部分从发射前/发射后各个阶段到标称作战的平稳过渡，对于保证Ariel任务的成功，科学回报和影响至关重要。定义了预期的科学数据产品，并提出了具有代表性的数据处理管道。
