Study on joint passive localization using time difference of arrival and frequency difference of arrival to improve the accuracy of four-satellite localization

In order to reduce the influence of time-difference-of-arrival measurement error on localization accuracy of time-difference-of-arrival-based four-satellite localization, we first introduce the frequency-difference-of-arrival information to the existing four-satellite time-difference-of-arrival loca...
