摘要

The observable degree is significant for the airborne Position and Orientation System (POS), and is a key parameter that reflects accuracy and rapidity of filter. The conventional mathematical method based on singular value decomposition cannot analyze the impact mechanism of movement on observable degree, and is impracticable to determine the movement of observable degree improvement. To solve the problem, an instantaneous observable degree model based on movement measurement for airborne POS is proposed to demonstrate the relationship between instantaneous movement and observable degree. The instantaneous observability matrix in the model is established to reduce analytical complexity. Experiment results show that the proposed model is valid to determine how to improve observable degree. (C) 2018 Elsevier Masson SAS. All rights reserved.
