The Tersus GeoBee30 is a dedicated and cost- effective solution to transmit or receive Ntrip
corrections. With Tersus Ntrip Caster Service, Ntrip
Modem and David30 GNSS Receiver, the
GeoBee30 opens the possibility for users to
transmit Real Time Kinematic (RTK) corrections via
Internet (Ethernet or 2G/3G/4G) in a simple, userfriendly
way, just using a SIM card or Ethernet
cable without any need of a static IP. GeoBee30
can also work as GNSS Rover to receive RTK
corrections from Tersus Ntrip Caster or any CORS
service.

Ntrip server mode: use David30 GNSS receiver to
create a base station. This temporary base or CORS
are for surveying, agriculture, UAV, machine
control, and etc. It is also ideal for deformation
monitoring. Tersus GNSS Inc. provides Ntrip Caster
to transfer data.

Ntrip client mode: connect David30 or other
Tersus GNSS receivers to Tersus Ntrip Caster or any
Ntrip/CORS service. David30 is mainly used for
surveying, and also used as a GNSS sensor in
various applications, such as mobile mapping, machine control, precision agriculture, and etc.
