The Tersus GeoBee is an affordable permanent reference station, for transmitting or receiving NTRIP corrections. When combined with Tersus NTRIP Caster Service, NTRIP Modem, and David30 GNSS Receiver, the GeoBee enables users to easily send Real Time Kinematic (RTK) corrections via Ethernet, 2G/3G/4G connections using just a SIM card, or Ethernet cable, without requiring a static IP. The NTRIP caster service supports multiple bases simultaneously.
