This information applies to Geode GNS3M, Geode GNS3H, Spire, and Archer 4 with GNSS expansion.

Juniper Systems GNSS receivers—Geode GNS3M, Geode GNS3H, Spire, and Archer 4 with GNSS expansion—are compatible with the Iowa Department of Transportation's Real Time Network (IaRTN) RTK network.

To connect a Juniper receiver to IaRTN RTK network, use one of the following software options:

  • Juniper Connect — Juniper Systems software utility that connects your GNSS receiver to a third-party mapping software, such ESRI Field Maps.

  • Uinta — Juniper Systems mapping and data collection software

After you've downloaded and installed either Juniper Connect or Uinta on your mobile device, complete the following steps.


Step 1Create an account with the Iowa DOT RTN network.

Create your account on the official IaRTN website: https://iowadot.gov/consultants-contractors/design/iowa-real-time-network


Step 2Connect your GNSS receiver to your mobile device.

Using the software you've selected (Uinta or Juniper Connect), connect your GNSS receiver to your mobile device.

For instructions on connecting your GNSS receiver, see


Step 3Set up the RTK connection profile.

Set up the RTK connection profile for IaRTN in Juniper Connect or Uinta.

Use the following information:

Note: If the IP address does not work, verify the address with IaRTN or your network administrator.

  • Mount point—Download and select the mount point appropriate for your location. If you are unsure which mount point to select, refer to the IaRTN mount point descriptions: https://iowadot.gov/media/1388/download?inline
