Research output: Contribution to conferencePaperpeer-review


Recently, GPS has been spreading rapidly for its confidence and usefulness, and now it is used in various situations. But in bad situation, such as in valley between tall buildings, we often cannot see over 3 satellites. We research and evaluate several 2-dimensional positioning to improve the accuracy. In Time Fixed method simulation, we improved the accuracy of positioning.
