Blog Article

Aiming to advance the coning algorithm performance of strapdown inertial navigation systems, a new half-compressed coning correction structure is presented.The half-compressed lamps algorithm structure is analytically proven to be equivalent to the traditional compressed structure under coning environments.The half-compressed algorithm coefficients allow direct configuration from traditional compressed algorithm coefficients.A type of algorithm error model is defined for coning algorithm Nutritional Yeast performance evaluation under maneuver environment conditions.Like previous uncompressed algorithms, the half-compressed algorithm has improved maneuver accuracy and retained coning accuracy compared with its corresponding compressed algorithm.

Compared with prior uncompressed algorithms, the formula for the new algorithm coefficients is simpler.
