Abstract :
Cm-level high accuracy real-time GPS positioning system is realized nation wide in Japan based on networked Real Time Kinematics GPS (RTK-GPS), and has been commercially operated by Mitsubishi Electric Co. named PAStrade, Positioning Augmentation Services, since September 2003. Also we have recently devised more convenient method at submeter or decimeter accuracy using low cost and compact code-ranging GPS receiver utilizing correction data fed from PAS system. Both of these methods will reduce time and cost significantly to produce precise satellite imagery based on Ground Control Point (GCP), as well as to update maps in geo-centric coordinate, which is necessary to use satellite imagery operationally with GPS
