The  general  structure  of  the  pedestrian  navigation  system  (PNS)  is  presented.  PNS  assessment  task  assigned  by  the adopted models of inertial navigation system (INS) and pedestrian errors is being set up. Information processing algorithm of  a  pedestrian  navigation  system  is  considered  that  implements  the  integration  of  inertial  sensors  measurements  and updating  information  from  an  external  source  as  a  biomechanical  motion  model.  Results  of  simulation  modeling  are presented.  It  is  demonstrated  that,  within  the  limits  of  the  adopted  models  of  sensor  errors  and  pedestrian  motion,  the accuracy of determining the current coordinates fits into pedestrian navigation systems requirements. The directions for future  research  are  determined:  practical  accuracy  assessment  of  the  system  based  on  the  real  pedestrian  movement data in different conditions, improvement of models and algorithms for measurement data processing.
