| 抄録(英) | This paper describes the development of RF front-end equipment of a wide band high precision satellite navigation receiver to be able to receive the currently available GPS navigation signal and the GALILEO navigation signal to be developed in Europe in the near future. The receiver to be developed in this project could be used for the application of sensor station and reference station for the global navigation satellite system. The wide band satellite navigation receiver with high precision performance is composed of L-band antenna, RF/IF converters for multi-band navigation signals, and high performance baseband processor. The L-band satellite navigation antenna is able to be received the signals in the range from 1.1GHz to 1.6GHz and from the navigation satellite positioned near the horizon. The navigation signal of GALILEO navigation satellite consists of L1, E5, and E6 band with signal bandwidth more than 20MHz which is wider than GPS signal. Due to the wide band navigation signal, the IF frequency and signal processing speed should be increased. The RF/IF converter has been designed with the single stage downconversion structure, and the IF frequency of 140MHz has been derived from considering the maximum signal bandwidth and the sampling frequency of 112MHz to be used in ADC circuit. The final output of RF/IF converter is a digital IF signal which is generated from signal processing of the AD converter from the IF signal. The developed RF front-end has the C/N0 performance over 40dB-Hz for the -130dBm input signal power and includes the automatic gain control circuits to provide the dynamic range over 40dB. |
