IET Radar, Sonar &Navigation, Volume 19, Issue 1, January/December 2025.This work explores underwater TMA by incorporating time delay and Doppler frequency measurements along with angle data, eliminating the need for own‐ship manoeuvre and improving estimation accuracy in presence of non‐Gaussian sensor noise. Furthermore, since the own‐ship's position is inherently uncertain due to navigation errors, this work addresses ...

Decrease in Accuracy of a Rotational SINS Caused by its Rotary Table's Errors
International Journal of Advanced Robotic Systems, 2014 We call a strapdown inertial navigation system (SINS) that uses the rotation auto-compensation technique (which is a common method to reduce the effect of the bias errors of inertial components) a ‘rotational SINS’. In a rotational SINS, the rotary table
