Inside YouCORS

See the stream. Find the connection. Know what happened.

Open a base session to check incoming traffic, inspect individual rover connections, and review events when equipment needs attention.

Is the base sending data?

Check observed throughput and spot gaps in the session history.

Which devices are connected?

Inspect each rover’s received data, connection duration and latest reported status.

What happened before the call?

Review connection events and previous sessions for the same base.

Built around your working day

Start with one base. Bring the rest of your fleet.

A local survey team, equipment moving between sites, or a change of caster: start with the setup you already have.

One base. Several rovers.

Publish your base stream and give each rover its own credentials. Use an internet connection where a radio link is impractical.

Set up your first connection

Several sites. One equipment fleet.

Organize base streams by project and manage access for survey rovers and compatible machinery as they move between jobs.

Moving from another caster?

Test one base and one rover before moving the fleet. Check your streams, device settings and access with your own equipment.

Your streams. Your access rules.

Keep the mountpoint list focused on your team.

Use your private caster for your own base streams. Give them recognizable names so operators can find the right source for the job.

  • Organize streams by site, project or farm.
  • Create separate NTRIP credentials for each device.
  • Change one device’s credentials without changing everyone else’s.

Looking for a replacement caster, jake_g described a UK fleet moving between job sites. After choosing YouCORS, the user reported that the fleet was working well and highlighted seeing only their own mountpoints.

Setup and outcome reported by jake_g in two public posts. Figures describe that user’s fleet, not a plan limit.

Chosen for an easier first setup.

After trying several NTRIP casters, Noel Burton described YouCORS as the easiest to set up and shared a video showing his Reach RS2 configuration.

Multi-base operations · Nearest Base

One connection name for a group of bases

Give a rover one group name for several bases. As it sends its position, Nearest Base selects the closest eligible connected base; the connection name stays the same.

Requires periodic GGA from the rover, valid base coordinates and correction streams compatible with your receiver.

After a source change, check the rover’s RTK status. Switching does not guarantee an uninterrupted RTK fix or immediate recovery if a base disconnects.

Included with Pro, Enterprise and the trial. Requires a supported dedicated instance.

Read the Nearest Base setup guide
Two base streams in one nearest group. A rover sends its GGA position and receives corrections from the selected base.
Conceptual example from the setup guide. Selection depends on the rover’s position and the group’s connected bases.

Pricing

Choose a plan for your equipment

Start with the number of base streams and device credentials you need. Choose Nearest Base for groups of bases, or Relay to receive an external stream.

The 3-day trial includes both Nearest Base and Relay, regardless of the plan you choose afterward.

A mount point identifies a base stream. A client is an NTRIP login for receiving corrections. These limits count the mount points and client credentials created in your account.

Test YouCORS with your own equipment

Start small. Confirm that your base and receiver work together before connecting the rest of your fleet or choosing a plan.

  • 1. Connect one base.
  • 2. Connect a rover or machine.
  • 3. Check correction delivery and RTK status.

Before you connect your equipment

Does YouCORS provide the RTK base stations?

YouCORS hosts the private NTRIP infrastructure that distributes your correction streams. You supply the base stations and compatible rovers, or an authorized external NTRIP source using Relay on an eligible plan.

Can we move from another NTRIP caster?

Start with a trial and one base/rover pair. Configure the YouCORS host, port, mount point and credentials on those devices, then verify correction delivery and RTK status. Once tested, move the remaining equipment in stages. Discuss your setup with us if you need help planning the change.

Can we move a base station between job sites?

Yes. Set up the base at the new site, verify its position and reconnect its stream. For Nearest Base, check the coordinates used by the group and reconnect affected bases after changing them.

What does our equipment need to support?

Your base must be able to publish an NTRIP correction stream, and your rover must be able to receive it over the internet and use its correction format. Nearest Base also requires periodic NMEA GGA position messages from the rover.

Does Nearest Base guarantee a continuous RTK fix?

Nearest Base selects a connected base stream; it does not create a virtual reference station or combine corrections. A receiver may need to re-establish its RTK solution after a change. Selection depends on position updates and available group members.

What should we test during the free trial?

Connect a base, configure a rover, confirm that correction data is arriving and check RTK status on your equipment. The 3-day trial includes Nearest Base and Relay, so you can evaluate your actual field setup before choosing a plan.
