A Method for Land Vehicle Gravity Anomaly Measurement Combining an Inertial Navigation System, Odometer, and Geo-Information System

Land vehicle gravity anomaly measurement relies heavily on global navigation satellite system (GNSS).However, when gravity measurement is carried out in special environments such as forests, valleys and tunnels, GNSS observation quality will inevitably decline, which directly affects the accuracy of gravity anomaly measurement.From the point of vie
