In this paper, we explore the use of wireless mesh networks (WMN) for the purpose of exchanging GPS raw data within GPS stations in a WMN to support real-time in-network processing of low-cost single-frequency GPS devices. A proof of concept deployment with a small number of GPS stations was studied. This experiment validates the feasibility of using WMN to enable real-time in-network processing in a dense GPS network for deformation monitoring. The experimental results demonstrated a significant reduction in station location errors when differential epoch-by-epoch processing method is used and provides real-time relative location between stations in the network.
