Long baseline rtk using a secondary base receiver a non-continuous data link and a wireless internet connectivity

Abstract

The system and method for long baseline RTK survey are disclosed. The system includes a primary base station (PBS), a secondary base station (SBS), a primary data link between the PBS and the SBS, and a secondary data link between the SBS and a rover. The PBS, the SBS, and the rover are equipped with satellite antennas for satellite navigational purposes, and with the wireless Internet data accesses devices (WIDAD). The long baseline vector between the PBS and the rover is established by combining the primary baseline vector between the SBS and the PBS and the secondary baseline vector between the SBS and the rover. The PBS is placed in a position with a known location. The PBS wirelessly downloads its logged set of data into the Internet server using the (PBS-WIDAD). The SBS determines its precise position coordinates by accessing wirelessly the PBS logged data on the Internet server using the (SBS-WIDAD). The rover determine its position coordinates in real time by accessing SBS directly using the (Rover-WIDAD), or determines its coordinates using the batch delayed delivery method by wirelessly accessing the SBS position coordinates published on the Internet server.
