Towards tropospheric delay estimation using GNSS smartphone receiver network

Information on the water vapor distribution of troposphere is useful for weather monitoring and forecast. Water can be estimated from tropospheric delays produced by high-grade Global Navigation Satellite System (GNSS) receivers. This type techniques currently used in data assimilation process Numerical Weather Prediction (NWP) models, especially, limited areas covered these GNSS networks. We consider a new collaborative crowdsourcing-based alternative obtaining meteorology measurements. It relies smartphone receiver network, hence promises to expand use into not high-end In order assess feasibility estimating using such networks, it proposed system architecture that supports estimation network. Next, presented simulator test-bed has been developed emulate representative way performances. The main motivation behind provides controlled environment testing our method.
