SETTING OF MARINE STRAPDOWN INERTIAL NAVIGATION SYSTEM (SDINS)

摘要

FIELD: instrument making.SUBSTANCE: claimed marine strapdown inertial navigation system decreases the initial setting errors under conditions of heaving without increase in the time of availability. Claimed setting is implemented by the use of corrections to the accelerometers signals generated from the data on angular velocities, angular accelerations and the distance between the SDINS centre and the vessel heaving centre.EFFECT: higher response.5 dwg
