Applied Bionics and Biomechanics, Volume 2024, Issue 1, 2024.Step length estimation (SLE) is the core process for pedestrian dead reckoning (PDR) for indoor positioning. Original SLE requires accurate estimations of pedestrian characteristic parameter (PCP) by the linear update, which may cause large distance errors.

Code Optimization for Strapdown Inertial Navigation System Algorithm
, 2018 Inertial navigation systems are in common use for decades due to its advantages. Since INS outputs are usually used for inputs in different control algorithms (depending on applications), INS will induce certain errors and limitations. This chapter deals with optimization of the inertial navigation algorithm against limitations due to the accuracy and ...
