Your Own RTK



Agricultural machine auto-steering requires high accuracy positioning (cm – dm level) high quality GNSS equipment on the tractor/harvester

correction service to improve absolute GNSS accuracy

Corrections may come from a global service provider via geostationary satellites (PPP)

a local GNSS base station via UHF radio link (RTK)

a local or regional GNSS infrastructure via the Internet(RTK, network RTK) – no need for radio repeaters

Internet-based correction dissemination requiresmobile Internet access and relies on the Ntrip protocol

Alberding GmbH offers: Your Own RTK

Your Base Station Alberding GmbH provides GNSS base station hardware and can assist you

with installation, receiver configuration and station coordination

Your Ntrip Caster The Alberding Ntrip Caster software distributes RTK corrections via the Internet

Data conversion allows to support any base station and rover receiver types

User accouts and data streams can be managed through the web interface

Your RTK Service We help you quickly launch your own cm accurate RTK service

Your investment is safe: the infrastructure can be easily expanded at any time



Alberding Ntrip Caster

Main purpose: distribute RTK corrections via the Internet

Designed for mass usage can handle hundreds of base stations and thousands

of simultaneous user connections

Can be installed on a local PC to work in single station mode

central server to operate in multi-station mode

Input data from Ntrip Server, another Ntrip Caster, TCP or UDP port

Available for Linux OS There exists a basic Windows version w/o GUI interface

Available for purchase or as a service provided by Alberding GmbH



Alberding Ntrip Caster advantages

Web interface for system configuration, data and user management and monitoring

Nearest base station auto selection

Map display

Fleet management

User access data export for billing

Support of multiple ports and virtual casters

Different access levels (admin, subadmin, user)

Real-time fleet management

About us Your Own RTK > Fleet management GNSS & GIS solutions


Real-time map display of stations and users



Real-time fleet management – user status table



Real-time export of user information to SQL DB

username Ntrip mountpoint used connection start/stop times position number of SVs DOP correction data age base station ID distance to base station RTK fixing status GSM service provider ID IP address etc.

Allows for complex SQL queries Performance statistics can be easily derived

e.g. ratio of RTK fixed rovers in different geographical regions

Important information for service quality improvement – weak points of service

About us Your Own RTK Data collection

Low-cost GNSS & GIS solutions for fielddata collection

GIS becomes indispensable for the ag market

Ability of GIS to analyse and visualise agricultural environments and workflows is beneficial to those involved in the farming industry


GIS use in agriculture: Land and property management (cadastral data) harvest analysis selection of prospective planting sites in-field data collection determining irrigation requirements company-wide information portal

About us Your Own RTK Data collection > GNSS & GIS in the ag market

Benefits of using GIS in the farming industry


Integrate & collect valuable ground data that cannot be

gathered via satellite

Less paperwork, less double data

entry, less confusion etc.

Collect georeferenced samples & apply statistical processes to the samples

GIS in the ag market
