Indeed, the local ties available at the ITRS Center for a certain number of co-location sites are now old by 10 to 20 years. In this respect, we would greatly appreciate the contribution of the national mapping and space agencies investing and operating co-location sites, which constitute the main foundation of the ITRF. More details regarding the local tie survey are available in the ITRF2013 CfP.
