Evaluation of EPOS-RT for Real-time Deformation Monitoring

Abstract

With the development of the EPOS-RT software system at GFZ, various tests have been performed to target some high precision applications such as real-time network deformation monitoring and that of based on real-time PPP (Precise Point Positioning). The paper provides an overview of the main features of the EPOS-RT software and focuses on the software performance assessment. The case studies of real-time detection of the well controlled station motion, using a network with stations separated by distances between 123 Km and 482 Km, show kinematic position accuracy at 7 mm in horizontal components and better than 2.5 cm in vertical component. Results from analysing real earthquake dynamics have demonstrated some unique features of the system and its capability of attaining mm accuracy in real time.
