Standalone GNSS Dataset: Open Field, ETFE Polytunnel, and Glass Greenhouse Measurements Alex Schofield (25033309) Migrated from ePrints This dataset supports the study "A comparative study of precise positioning through the use of GNSS in agricultural polytunnels and glass greenhouses." It includes raw and processed GNSS observations collected using both a high-end survey-grade receiver and a mass-market dual-frequency receiver. Static measurements were recorded at 1 Hz over two-hour periods in three environments: open field (baseline), ETFE polytunnel, and Cambridge-style glass greenhouse. The data includes binary .ubx logs, converted .gps files, and CSV exports for analysis. These observations enable assessment of standalone GNSS positioning precision in covered agricultural environments, and support research into RF signal attenuation and structural interference from ETFE and glass frameworks. 2026-09-17T16:04:14Z Dataset Dataset 10.82444/warw.33900328.v1 https://figshare.com/articles/dataset/Standalone_GNSS_Dataset_Open_Field_ETFE_Polytunnel_and_Glass_Greenhouse_Measurements/33900328 CC BY 4.0
