Abstract

The paper discusses the on-board navigation system, which is the part of an Advanced Surface Movement Guidance and Control System (A-SMGCS), intended for use on-board of airport vehicles. The structure of the complex is offered, its basic characteristics are considered. The technique of simulation and hardware-in-the-loop modeling is given, in accordance with which the numerical investigation of system’s properties using the developed software is performed. Several scenarios of modeling are considered. One of the scenarios includes initial operation of satellite navigation system (SNS) operating in differential mode and the gap of SNS when the system continues to work in autonomous mode - by complex processing of information from the strapdown inertial navigation system (SINS) based on micro-mechanical gyroscopes and accelerometers, on-board odometer and a magnetic compass. The accuracy of navigational maintenance needed to meet the requirements of Doc 9830 AN/452 ICAO is estimated. The results are given in the form of estimation error of basic parameters and their standard deviation.

Keywords:
