1. An aircraft landing guidance support system comprising:
a correction GPS mobile station including a GPS receiver and an RTK-GPS receiver; and
an information processing equipment including a display unit, the information processing equipment configured to process, moment to moment, a GPS signal and an RTK-GPS signal received by the correction GPS mobile station, wherein
the GPS receiver and the RTK-GPS receiver are installed on an aircraft, and a position of the GPS receiver and the RTK-GPS receiver change with the position of the aircraft,
the RTK-GPS signal includes difference information between a geoid height correction coordination of a base position and known GPS coordinates of the base position, the geoid height correction coordination being obtained by performing a geoid height correction at coordination of the base position and by correcting installation altitude information for an installation position at which a correction GPS reference station and a landing ground point is set when the correction GPS reference station or the landing ground point is set high above a ground surface, the landing ground point being set as a position for a reliable landing, and wherein
the information processing equipment is configured to:
record landing route data containing landing route information;
record current position information data containing, as altitude information of the correction
GPS mobile station, information being obtained by correcting an altitude of the correction GPS mobile station based on the difference information included in the RTK-GPS signal, wherein the altitude of the correction GPS mobile station is calculated based on the GPS signal which the correction GPS mobile station has received; and
display the landing route data and the current position information on the display unit of the information processing equipment.
