It is a reference station application to be used as RTK-GNSS in combination with the GNSS calculation application "Civil Surveyor for QZSS" for surveying.
By combining this app with Civil Surveyor for QZSS, RTK positioning with no communication distance limit between the reference station and mobile station can be realized at a significantly lower cost than before for surveying purposes.
(Please use at an appropriate distance according to the purpose of the object to be measured)
To connect this reference station (WEB-RTK Base app) to the mobile station "Civil Surveyor for QZSS" app, a contract to use the WEB-RTK service provided by JPS is required.
