%X Gravity anomaly data are commonly used in the gravity aided inertial navigation simulations.The study on the ability of the gravity gradient to aid an inertial navigation system,however,is lacking.Simulations of multiple routes in the same area with SITAN algorithm have been conducted based on the gravity anomaly and vertical gradient of gravity data.Statistical analysis indicates that the initial localization and matching aided navigation results are better from the vertical gradient of gravity data than t...
