Latitude Determination and Error Analysis for Stationary SINS in Unknow-Position Condition

Sensors, 2020
The initial geographic latitude information is the key to the self-alignment of the strapdown inertial navigation system (SINS), but how to determine the latitude when the latitude cannot be obtained directly or in a short time?
