The Bureau of Products and Standards (BPS) supports GGOS in its goal to obtain consistent products describing the geometry, rotation and gravity field of the Earth, along with its variations in time. The main purpose of the BPS is to keep track of adopted geodetic standards and conventions across all IAG components as a fundamental basis for the generation of consistent geometric and gravimetric products. The work of the BPS is primarily built on the IAG Service activities in the field of data analysis and combinations. The BPS acts as contact and coordinating point regarding homogenization of standards and IAG products. As a key activity the BPS has performed an assessment of the standards and conventions currently adopted and used by the IAG and its components for the processing of geometric and gravimetric observations and as a basis for the generation of IAG products. The results of this BPS inventory were published in the IAG Geodesist's Handbook 2016.

In this contribution we present the role of the BPS and summarize the major findings of its recent activities. Some examples of the product-based BPS inventory on standards and conventions will be highlighted. It will also be discussed how to proceed with the recommendations given in the inventory and how to resolve inconsistencies and gaps in order to improve the consistency of IAG products. This presentation will also give an overview of the contributions of the BPS towards the integration of geometric and gravimetric parameters and the development of new products, required to address important geophysical questions and societal needs.
