Virtual Reference Station – Generic Term “Real Time GPS Network” Describes a network of GPS (GNSS) base stations Each occupying known surveyed point Each streaming data to a server Server has identity on the Internet Users connect to the Internet Users authorized to stream server data Why VRS? GPS error is partly due to baseline distance Error of GPS plus 1ppm – 1 ppm (Part per Million) 1 millimeter of error per kilometer of distance RTK – Real Time Kinematic (1992) Original system - one base, one rover Accuracy dependent on distance to local base VRS – Virtual Reference Station Stay inside the geographic network VRS and How It Works VRS < 10 cm < 10 cm How to Connect? User must get to the Internet WiFi Cellular Modem (internal or external) Cellular Air Card to Router to Repeaters New Product to Access Internet WiFi Ranger Portable, batterypowered mobile wireless N router Capable of automatically connecting to repeaters Internal or External Modem?
