An Innovative High-Precision Scheme for a GPS/MEMS-SINS Ultra-Tight Integrated System

open access: yesSensors, 2019
The Doppler-assisted error provided by a low-precision microelectromechanical system (MEMS) strapdown inertial navigation system (SINS) increases rapidly. Therefore, the bandwidth of the tracking loop for a global positioning system (GPS)/MEMS-SINS ultra-
