| Abstract: |
| According to the characteristics of narrowband and long duration of c
ommunication and TT&C signals, the realizable frequency
measurement precision of the signals in engineering is analysed,and the feasibi
lity 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 satellit
e orbit altitudes are computed according to 5km localization precision requireme
nt.The
conclusion is useful for argumentation and analysis of localization precision in
dexes in single satellite passive localization system. |
