GNSS-IR Retrieval of Soil Moisture in Sugarcane Plantation Based on Cross-Correlation Satellite Selecillation is selected. Then, based on the interference phase of each satellite obtained by nonlinear least squares fitting, a cross-correlation satellite selection method (CCSSM) is established. The available satellites are selected by setting a reasonable threshold. Finally, three multi-satellite c

Modeling and Performance Evaluation of TomoSAR System Based on Reflected Signal of Beidou NavigationAR and MEO SAR systems have the advantages of shorter revisit period, longer observation time and larger beam coverage area theoretically, there are no satellites in orbit at present. GNSS-TomoSAR, based on the reflected signals of navigation satellites, uses the in-orbit navigation satellite as the

Soil Moisture Inversion Based on Dual-Frequency Signal of QZSS GEO Satellite inversion models were evaluated for L1 C/A and L5 signals, and it is found that the signal quality of L5 is better than that of L1 C/A in QZSS-R soil moisture inversion. For the Topp model, the RMSE (Root Mean Square Error) of L5 and L1 C/A inversion results are 0.0240 cm./cm. and 0.1725 cm./cm.. F

The accuracy of static PPP solutions is at the centimeter level, while it is at the decimeter level for the dynamic PPP solutions. The central stations have better results than those at the boundary of the service areas. For exploring the a
