Everything you need to know about RTK
From GNSS basics to configuring tractor terminals and troubleshooting in the field.
Basics
What is RTK and how GNSS positioning works
What RTK is and how it works: GNSS satellites, base station and rover, RTK FIX and FLOAT status, and why a base station network gives centimetre accuracy.
NTRIP and RTCM – how RTK corrections travel
How RTK corrections travel over the internet: NTRIP caster, mountpoint and sourcetable, sending GGA, NTRIP v1/v2 and the RTCM 3 MSM messages of our bases.
Getting started
Connecting to RTK.ba via NTRIP – step by step
NTRIP setup step by step: host rtk.ba, port 2101, mountpoint AUTO, username and password – what goes where and how to confirm that you have RTK FIX.
Tractor auto-steer RTK – John Deere, Fendt, CNH
RTK for tractor auto-steer via NTRIP: what your receiver needs and where to set it up on McCormick, John Deere, Fendt, Case IH, New Holland, Claas.
RTK for survey rovers, drones and apps
NTRIP setup for survey rovers (CHC, Stonex, Emlid), u-blox F9P modules, DJI RTK drones and Android apps – where to enter your RTK.ba connection details.
Advanced
What RTK accuracy depends on
What RTK accuracy depends on: distance to the base, sky view, multipath, antenna, ionosphere and age of corrections – and what to do for a stable FIX.
Coordinate systems – WGS84, ETRS89 and projections
Why GNSS coordinates differ from cadastral ones: WGS84, ETRS89 and national projections, and how to set up the transformation in a controller or GIS.
Support
No RTK FIX? Troubleshooting NTRIP connections
No RTK FIX or can’t connect? The most common symptoms (401, timeout, stuck in FLOAT, no GGA) and what to check, in order – with a fix for each one.
User panel – account, subscriptions and support
The RTK.ba user panel: connection and base overview, NTRIP details to copy, subscription and expiry, invoices, support tickets, Telegram alerts and 2FA.
RTK/GNSS glossary
Glossary of RTK and GNSS terms: AB line, age of corrections, baseline, caster, GGA, mountpoint, MSM, PDOP, RTCM, VRS and other terms seen in terminals.
