Abstract:	We have developed and released the new Real Time Kinematic (RTK) GPS positioning platform system using networking technology. This system performs high accuracy RTK processing by using the observation data transmitted from GPS receiver it's connected by network (TCP-IP communication). It realizes unitary management GPS receiver information and connection by using Application Program Interface (API) for integration to various applications. We have also established brand new Application Service Providers (ASP) for RTK positioning with new RTK-GPS technology using Japanese nation wide GPS network named GEONET that established by GSI (Geographical Survey Institute). This service realized to provide centimeter accuracy RTK positioning using Virtual Reference Station (VRS) and our network based GPS receiver unit (NetSurv), and it realizes easy to use RTK for Surveyor in all over Japan. This paper describes the concept of our Server based RTK platform and specialized GPS receiver unit, then explain Japanese Real Time GPS data streaming infrastructure which established by GSI and operate by JAS, then finally explain our unique ASP based RTK processing system by using all of techniques and infrastructure which explained the above.
