I need RTK bridging support

TerraStar offers two options for users relying on RTK corrections and looking for a seamless positioning experience with maximum coverage. TerraStar’s RTK ASSIST and RTK ASSIST PRO provide reliable and accurate position bridging during RTK outages and can offer an independent PPP solution if you start up outside of your RTK coverage. Additionally, bridging corrections are delivered via L-Band satellite, meaning you can rely on an independent source of corrections if your internet connection or radio goes out.

RTK ASSIST

  • Maintains 5 centimetre-level positioning for RTK correction outages up to 20 minutes
  • Seamlessly bridges corrections during brief RTK outages from tree lines, buildings, or low cellular bandwidth

RTK ASSIST PRO

  • Supports 3 centimetre-level positioning for lengthy or indefinite RTK outages
  • Enables independent PPP services for high accuracy solutions outside of areas with existing RTK infrastructure, network coverage or base stations
  • Seamlessly operates in the background throughout large project areas where dropped signals or lost base station lines are frequent hazards
