IEEE/ICACT20210158 Question.3 Questioner: franklinlu888@outlook.com 2021-02-08 오전 11:06:31	IEEE/ICACT20210158 Answer.3 Answer by Auhor charnon2002@hotmail.com 2021-02-08 오전 11:06:31
Compared with the professional GPS receiver, the accuracy of the smartphone for GPS or GNSS might be limited. However, the positioning of WIFI AP improves the accuracy of positioning. Do you think that improving the distance accuracy from WIFI AP will be easy for the better performance of your positioning system?	We think using Wi-Fi positioning and using GNSS positioning are different solutions, we think Wi-Fi might not help with the accuracy of our solution. Our research focuses on the application of a dual-frequency GNSS chip embedded in smartphones, allowing smartphones with only dual-frequency GNSS observations to be recorded. Our applications can be used where there is no cellular and Wi-Fi signal available.
