Description
Summary:New Zealand has a network of approximately 190 Continuously Operating Reference Stations (CORS) operated by GeoNet, is a project housed within GNS Science. The GeoNet continuous GNSS network (cGNSS) includes the 37 stations that make up the Land Information New Zealand (LINZ) PositioNZ network. These stations are run in partnership by the two agencies. The New Zealand CORS stations make a significant contribution to New Zealand's geospatial infrastructure and to international geodesy. Further, the CORS stations have been used to identify more than 25 slow-slip events (SSEs) associated with the Hikurangi subduction zone, play an important role in volcano monitoring and have the potential to identify tsunamigenic earthquakes. This paper will discuss how the two networks were established, how they have evolved since the first stations were established in 1995 and the significant contribution of the late John Beavan.
