GeoBee30
NTRIP and GNSS Reference Station Solution
Share RTK corrections
over the internet.
Broadcast data from your base station or receive corrections for your rover using the David30 GNSS receiver and NTRIP modem. Operate over Ethernet or a SIM connection without a static IP address.

Multi-GNSS tracking
Multi-constellation support in the David30 receiver.
Two operating modes
Server mode broadcasts corrections; Client mode receives them.
Wired internet
Primary network connection for the reference station.
Cellular connectivity
Mobile network backup for the Ethernet connection.
Internal storage
Storage for data collection; 32 GB option available.
System integration
Serial communications with different field systems.
One system.
Two different roles.
Configure GeoBee30 as a reference station broadcasting corrections or as a GNSS rover receiving data from an NTRIP service.
Server: broadcast corrections
Send David30 correction data to rover receivers through an NTRIP Caster. Use it for temporary base or permanent reference-station installations.
Client: receive corrections
Connect to Tersus NTRIP Caster or compatible CORS services. Use the received corrections to operate David30 as a rover receiver.
Connect GNSS data
to the network.
The TR600 NTRIP modem handles data communications between the GNSS receiver and the internet. Ethernet and cellular options allow corrections to be sent or received without a static IP address.

Choose the connection
communications infrastructure.
Bring survey data onto the network with Ethernet as the primary connection and 2G/3G/4G backup. Remote access simplifies station operation.
Generate GNSS data
Install the antenna and David30 receiver at your reference point and configure the station position.
Connect to an NTRIP service
Enter the caster details, user account and broadcast or reception settings.
Monitor data flow
Check connection status and correction data to operate your field systems.
From reference station
to field application.
GeoBee30 can serve different GNSS workflows that require correction data transmission.
Surveying and monitoring
Data communications for permanent reference stations, topographic surveys and deformation monitoring.
Agriculture and machine control
Provide GNSS data and RTK corrections for the positioning workflows of compatible systems.
UAV and mobile mapping
Integration with NTRIP-connected systems, subject to receiver and data-format compatibility.
Essential equipment
for installation.
