NTRIP RTK Corrections for Australian and New Zealand Precision Farming
Agricultural GPS corrections built for the paddock
VKLink is an Australian NTRIP RTK corrections network built around the way precision farming machinery is actually used in the paddock, by a precision farming technician who has been in those paddocks. Modern correction streams are often designed around surveying, mining, construction and high-end GNSS receivers. That is not always ideal for precision agriculture equipment, especially older displays, guidance receivers and modems working in poor mobile coverage.
Our aim is simple: reliable RTK corrections, lower data use, and compatibility with the agricultural GPS equipment farmers already own.
What makes the VKLink network different?
We charge per concurrent connection, not per user.
If you only need one machine connected at a time, you should not have to pay as though every machine is working at the same time.
Our network uses Australian and New Zealand reference stations with added VKLink stations where needed.
It supports GDA2020 as the normal Australian datum and NZGD2000 as the New Zealand datum.
Where older equipment or your farm mapping requires it, GDA94, ITRF2008, ITRF2014 and WGS84 streams are also available.
NTRIP correction formats for agricultural GPS
We support multiple RTK correction formats, including:
Reduced-message RTCM 3 for most receivers (our flagship)
RTCM 3 MSM for newer multi-constellation receivers
RTCM MSM3, 4, 5 and 6 for older receivers
RTCM 2.3 for older equipment
CMR and CMR+ for Trimble and compatible agricultural receivers
This matters because agricultural GPS equipment varies wildly. Some receivers are new and can use modern MSM streams. Others are older and only work properly with GPS/GLONASS or CMR-style corrections. Our network is designed to serve both.
Lower data use in rural areas
Many correction streams include everything a survey receiver might want. That can mean more satellite constellations, more messages, and more data than an agricultural receiver needs, or in many cases can handle.
We provide agriculture-focused streams that reduce unnecessary correction data where possible. That can help in marginal mobile coverage and can reduce the load on older displays and receivers.
Automatic NTRIP reference station selection
When you connect to an AUTO mount point, our network uses your receiver’s position to select a suitable nearby reference station. As you move, the system can move your connection to a better base while keeping the correction format you requested.
You can also connect directly to a specific reference station if you prefer.
As a side effect, your user portal gives you a de facto vehicle tracking interface. You can see where your machine is, how fast it is going, and the direction it is travelling.
Precision agriculture receiver compatibility
Our network has been built with real agricultural equipment in mind, including older Trimble, Case IH, New Holland and other receivers that can be fussy about correction formats and station messages.
Receivers known to work on our system:
Trimble: AG-252, AG-262, AG-372, AG-392, NAV-900, FM-1000, FM-750, and XCN-2050 (FM1000+ app).
Case IH and New Holland: AG252, AG262, AG372, AG392, NAV900, AFS Vector Pro, PLM Cygnus.
John Deere: Starfire.
Raven: RS1, 600s, and 700s.
Topcon: AGI-4.
AGCO: AG-382, and AG-482.
Ag Leader: Geosteer.
We support those options and more without needing separate networks for each one.
Precision farming RTK coverage
Our network utilises the CORS network with additional reference points. At this time, we have over 650 reference points across Australia with thousands of correction streams.
