摘要: Global navigation satellite systems (GNSS) signals offer a promising opportunity to perform mesoscale altimetry with worldwide coverage using small satellites. However, unlike the used in classical altimeters, GNSS have smaller bandwidth and lower transmitted power. This paper analyzes achievable height precision of Navigation Satellite System Reflectometry (GNSS-R) altimeters based on Cramer–Rao bound for time-delay estimation. Precision bounds composite GPS L1 L5 Galileo E1, E5, E6 spaceborne mission scenario are assessed, optimum receiver bandwidths which minimize them obtained.
