Real-Time In-Network Single Frequency GPS Processing for Deformation Monitoring

In this paper, the authors 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.
