DEAD-RECKONING SYSTEM OF USING ERROR CORRECTION AND METHOD OF USING THE SAME

摘要

PURPOSE: the dead-reckoning system piercing error correction only carried out with perambulator and compass provides a kind of basis for correcting GPS coordinate value by using information and moving relative to moving direction with real-time measurement. ;CONSTITUTION: the dead-reckoning system piercing error correction only carried out with perambulator and compass includes next step. The GPS receiver unit of GPS signal is received, so that the calculating of GPS coordinate value. About the information of acceleration and moving direction, receives and come acceleration sensor and geomagnetic sensor. Desired orientation and the received information of the GPS receiver unit for generating GPS signal is received with geomagnetic sensor measured about acceleration and moving direction by acceleration transducer and attitude angle, thus by calculate generate actual direction. The attitude angle on basis is corrected as in desired orientation, so that GPS coordinate value be made to be corrected. ;The 2013 of copyright KIPO submissions;[Reference numerals] (AA) starts; (BB) step receives the GPS of GPS signal and calculates the coordinate from GPS receiver; Step (CC) reception carrys out the acceleration of acceleration sensor to calculate the mobile moving direction that receives from geomagnetic sensor; (DD) step generates prediction direction and actual direction calculates attitude angle; (EE) time step calculates instant attitudes vibration angle and compensates for error attitude angle; (FF) step correction prediction direction is based on posture angle compensation GPS location coordinate; (GG) Zi Taijiaodu & Predetermined threshold?
