迄今为止，国际地球自转和参考系服务（IERS）的产品，如国际陆地参考系（ITRF）、国际天体参考系（ICRF）和地球定向参数（EOP），都是独立组合的，既没有进行技术内组合，也没有进行技术间组合，包括完整的方差-协方差信息。为了克服目前的IERS产品一代的这一缺陷，IERS在2001年1月实施了一种新的结构。这包括新的IERS联合研究中心（CRC）和IERS分析协调员（AC）。他负责IERS产品的长期和内部一致性。为了达到最高的精度和一致性，必须对多个空间大地测量技术共同的所有参数进行完全严格的组合。自2001年以来，IERS AC发起并协调了许多不同的项目和活动，以实现这一总体目标。现在，近三年的成果为最新的联合试点项目（CPP）奠定了理论和实践基础。该项目将在常规基础上准备生成联合IERS产品。
Until today the products of the International Earth Rotation and Reference Systems Service (IERS), like International Terrestrial Reference Frame (ITRF), International Celestial Reference Frame (ICRF) and Earth Orientation Parameters (EOP), are combined independently, neither intra-technique nor inter-technique combinations, including the full variance-covariance information are performed. To overcome this deficiencies in the present IERS product generation the IERS implemented a new structure in January 2001. This includes the new IERS Combination Research Centres (CRC) and the IERS Analysis Coordinator (AC). He is responsible for the long-term and internal consistency of the IERS products. To achieve the highest accuracy and consistency, it is crucial to proceed towards a fully rigorous combination of all the parameters common to more than one space geodetic technique. Since 2001 the IERS AC initiated and coordinated many different projects and campaigns towards this overall goal. Now the results of the last three years build the theoretical and practical base for the latest project, the Combination Pilot Project (CPP). This project will prepare the generation of a combined IERS product on a routine basis.
