Real-Time Kinematic (RTK) Troubleshooting Guide

1. Summary

A real-time kinematic (RTK) network sends error corrections from a known point to your GPS unit, ensuring precise location accuracy. These corrections depend on:

• A strong cellular data signal.
• A clear view of the sky.

For the best results, connect your GPS unit to an RTK stream sourced nearby. RTK licenses and compatible equipment are required. If credentials or RTK stream details are needed, contact the Locusview Help Desk Team.

This guide provides troubleshooting steps for resolving RTK connection issues using the Locusview Mobile App.

2. Prerequisites

• RTK license and compatible GPS equipment.
• RTK credentials:
  • Address (provided by Locusview Help Desk).
  • Port.
  • Username (case-sensitive).
  • Password (case-sensitive).
• A strong cellular data signal.
• Clear skies and an unobstructed view for GPS.
• Device-specific location settings:
  • Samsung Tablets: Location services must be on, and Google Maps must be active.
  • iPads: Location services must be enabled in Settings.

3. Step-by-Step Instructions

Step 1: Verify RTK Credentials

1. Open the Locusview Mobile App.
2. Navigate to the RTK Device Setup screen.

3. Check that the following credentials are entered correctly:

   • Address: Input exactly as provided without spaces.
   • Port: Enter the number exactly as provided.
   • Username: Ensure it is entered correctly (case-sensitive).
   • Password: Ensure it is entered correctly (case-sensitive).

   Important: Avoid adding extra spaces, especially at the end of the fields.

Step 2: Ensure GPS and Location Services Are Active

• For Samsung Tablets:
  1. Confirm Location Services are turned on.
  2. Open the Google Maps app:
     • If the location shows a map of the United States, tap the bullseye icon in the bottom right to enable precise location.
     • Confirm that the device zooms in on the current location.
• For iPads:
  1. Go to Settings on the iPad.
  2. Enable Location Services for the Locusview app.

Step 3: Connect to the RTK Server

1. In the RTK Device Setup screen, select Connect to Server.
2. Wait for confirmation of a successful connection.

Step 4: Select and Save the Correct RTK Stream

1. From the Stream List, select the appropriate RTK stream:
   • If Automatic Selection is available, prioritize it.
   • If not, select the stream that corresponds to the closest city or state. If you can't select a city, choose one of the VRS streams.
2. Tap Save to apply your stream selection.

Step 5: Verify RTK Connection Status

1. Return to the map screen in the Locusview app.
2. Check the status bar to confirm the RTK connection is active.

4. Troubleshooting Tips

• If the RTK connection fails:
  • Verify the Address, Port, Username, and Password for typos.
  • Ensure the device has a stable internet connection.
  • Make sure the correct RTK stream is selected and saved.
• If location services are not functioning properly:
  • For Samsung Tablets: Check that Google Maps is active and precise location is enabled.
  • For iPads: Ensure Location is turned on in Settings.
• If no RTK stream is listed:
  • Confirm that the RTK license is active.
  • Contact the Locusview Help Desk for additional assistance.

5. Additional Notes and Best Practices

• Always use Automatic Selection or State-based streams if available.
• Choose the closest city/state stream when automatic options are not available.
• Clear skies are required for optimal RTK accuracy.
• Ensure all credentials (Address, Port, Username, Password) are entered exactly as provided by the Locusview Help Desk.
