Global navigation satellite system (GNSS) positioning, including the global positioning system (GPS), is susceptible to multipath effects in urban areas and between tall buildings, which degrade positioning accuracy. In this study, to address this issue, we supplement GNSS positioning with information obtained through communication with LTE base stations, utilizing it as features for position estimation.Using this information, we propose a method that employs a neural network (NN).The proposed method builds long short-term memory (LSTM)-based NN model with a parallel structure.In this model, GNSS positioning information and LTE signal information are combined and input into LSTM with different structures.Features obtained from multiple information sources are used in a complementary manner to improve the accuracy of position estimation.Furthermore, the positioning accuracy of test data is evaluated to confirm the effectiveness of the proposed method.This evaluation considers positioning at unknown locations different from those used during training. |
