July 24, 2024 ACs. Combining products from individual ACs to produce robust operational products. Evaluating the combined products for performance and consistency. Disseminating official IGS combined products through an operational framework. Coordinating changes, developments, and improvements within the contributing ACs to use the latest models and standards. Evaluating the suitability of new ACs that wish to be recognized by the IGS. The ACC is responsible for establishing the detailed specifications for IGS products, while working closely with ACs and the IGS Reference Frame Coordinator. Additionally, the ACC works closely with the ACs in the generation of other IGS analysis products, including the content of the IGS ACC website (https://igs.org/acc/). The new NASA/GA+ ACC will undertake a phased approach to ensure a smooth and thorough transition towards a fully multi-GNSS IGS, enhancing the accuracy and reliability of future GNSS products, while working towards achieving the IGS strategic goal of “multi-GNSS Technical Excellence.”
