Geomagnetic Observatories are essential for the study of the Earth's magnetic phenomena, they allow the precise and continuous measurement of the geomagnetic field. They are built and operated according to rigorous international standards to ensure the acquisition of high-quality geomagnetic data. Given the nature of Quality Management Systems based on ISO 9001:2015, we consider that their implementation in a Geomagnetic Observatory, can be a valuable tool that allows monitoring the follow-up of international standards and ensuring their correct operation, thus guaranteeing high quality geomagnetic data.</p> <p>Some of the main advantages of implementing a Quality Management System and obtaining an ISO 9001:2015 certification include setting clear objectives, systematically analyzing risks that could affect both functionality and data quality, fostering a culture of continuous improvement, promoting of context analysis through a Strengths, Weaknesses, Opportunities, and Threats analysis; and strategic planning based on this knowledge. In addition, involving the senior management of the institution responsible can help raise awareness of the operation characteristics and needs. It also facilitates the continuous monitoring of user’s requirements and satisfaction, as well as the correct documentation of all procedures carried out for its operation.</p> <p>This study presents the registered experience in the implementation of a Quality Management System in the only Magnetic Observatory in Mexico: Teoloyucan. It details the operation of the observatory, including data acquisition platforms, transmission, reduction, management, and data publication. It also describes the Quality Management System implementation process in the data deployment procedures, highlighting its advantages, disadvantages, and challenges during its adoption.
