Abstract
Recognising the importance of improving the regional geodetic framework in the Asia-Pacific region, the Asia-Pacific Reference Frame (APREF) project call for participation was released in March 2010. The APREF project is a joint initiative of the Permanent Committee for GIS Infrastructure of the Asia-Pacific (PCGIAP) and the International Association of Geodesy (IAG). Currently, GNSS data from a Continuously Operating Reference Station (CORS) network of approximately 290 stations, contributed by 28 countries, is now available and processed by three Analysis Centres (ACs). The contributions of the ACs are combined into a weekly solution in SINEX format using the CATREF software. Three kinds of APREF products are available, rapid daily solutions which are produced using IGS rapid products, final daily solutions which are produced using IGS final products, and the weekly combined solutions. The core product of the APREF is the weekly solution; it provides a reliable time-series of the regional reference frame in the International Terrestrial Reference Frame (ITRF) and a quality assessment of the performance of participating Asia-Pacific GNSS CORS stations. In this presentation, we update the progress of the APREF project and perspectives towards a regional focus for cooperation in the definition, realisation and densification of the ITRF in the Asia-Pacific.
