| Abstract: | According to the characteristics of narrowband and long duration of communication and TT&C signals, the realizable frequency measurement precision of the signals in engineering is analysed,and the feasibility of realizing high precision localization of communication and TT&C signals on single satellite platform with frequency localization method is demonstrated. Furthermore, the demand of signal duration, carrier frequency,frequency measurement error and satellite orbit altitudes are computed according to 5km localization precision requirement.The conclusion is useful for argumentation and analysis of localization precision indexes in single satellite passive localization system. |
