RTK with external UHF radio is troublesome:

  • A lot of cables to manage
  • Recharge batteries every day
  • Rover must be in line of sight
  • Don't forget a second tripod for the antenna

If you're working within cellular coverage. Use YouCORS NTRIP caster service.

NTRIP caster map

We have NTRIP casters all over the world, so you don't need to worry about your RTK base station's data traveling too far to reach your rovers. This means less delay and more accuracy for your moving rovers, whether they are RTK drones or tractors. It also helps if you need high rate RTK survey.

NTRIP caster software

YouCORS uses a custom-built NTRIP caster that we call YCCaster. It's a modern and lightweight caster that can handle a lot of RTK connections even on a low-end server.

We also offer YCCaster as a standalone software for Linux, MacOS and Windows. The free version of the caster can support up to 20 connections from base stations and rovers at the same time. You can find out more about our caster on its page.

RTK base and rover setup

NTRIP protocol is compatible with most GNSS receiver manufacturers. The basic principle of setting up a base station and rovers for our casters is the same, but the details may vary.

In this video, you will learn how to set up Trimble R12/R12 receivers and Trimble Access 2022 for RTK mode with Mark White from Duncan-Parnell Geospatial.
