However, these nonlinear simultaneous equations include external factors, such as clock errors and multipath, which induce position estimation errors. Although this measurement error due to external factors is difficult to predict with statistical and physical models, it is necessary to predict this error in order to improve positioning accuracy. In this study, we consider the feed-forward neural network (FFNN) that learns GNSS measurement data collected using multiple base stations to estimate the pseudo-range error. GNSS measurement data collected in multiple environments are likely to accurately represent the pseudo-range error that depends on the surrounding environment. Correct the pseudo-range error with the correction value estimated by the FFNN and evaluate the positioning result. This paper shows the effectiveness of pseudo-range correction using neural networks trained on multiple base stations.","subitem_description_language":"en","subitem_description_type":"Abstract"}]},"item_1_description_25":{"attribute_name":"フォーマット","attribute_value_mlt":[{"subitem_description":"application/pdf","subitem_description_type":"Other"}]},"item_1_identifier_registration":{"attribute_name":"ID登録","attribute_value_mlt":[{"subitem_identifier_reg_text":"10.14988/0002000050","subitem_identifier_reg_type":"JaLC"}]},"item_1_publisher_15":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"同志社大学ハリス理化学研究所","subitem_publisher_language":"ja"}]},"item_1_publisher_16":{"attribute_name":"出版者（英）","attribute_value_mlt":[{"subitem_publisher":"Harris
