Does the work need vertical precision as well as horizontal? Can it absorb a pause in corrections?
Made for scheduled work that can absorb a pause
RTK Core is single-source network RTK with 3D precision wherever the network reaches. RTK Premium adds redundancy and a horizontal fallback beyond it.
< 1.5 cm horizontal, < 2.5 cm vertical
Instant fix
Best effort
Response < 4 h, business hours
Typical users are engineering crews and precision agriculture operations.
Made for work where horizontal precision is enough
RTK Access is PPP-RTK, horizontal only. If the work needs vertical, it needs the network: that’s RTK Core.
3–7 cm horizontal
Fix in under 1 minute
Best effort
Response 24 h, business hours
Typical users are utilities field teams, light robotics and consumer automation.
Marine, separate offer
Made for work on the water
RTK Seas combines coastal network RTK, nearshore PPP-RTK and offshore PPP in one service, on one account and one invoice.
2–10 cm 3D, by distance from shore
99% availability
Response 2 h, business hours
Typical users are hydrographic surveyors, dynamic positioning operators, and coastal and offshore contractors.
On RTK Premium the levels also work as a fallback chain: when a correction source drops, the service moves to the next network, then down to PPP-RTK, which is horizontal only, so the rover stays productive instead of dropping to standalone. None of the four services needs a base station of your own. Response times run in business hours, 09:00 CET to 17:00 ET.

After its first RTK supplier collapsed, Coptrz put Premium Positioning RTK in every demo kit and has run it for the last five or six years.

The argoBridgePilot turns vessel height, the measurement standard GNSS handles worst, into a safety-critical warning.
IoT SIMs work across multiple operators, so GNSS devices aren’t tied to one network.
