Initializing GPS Accuracy

Ephemeris data is information that the Halo Collar collects from GPS satellites, including their location and timing. This data helps provide accurate GPS readings. The collar aggregates this data over time to continuously improve its tracking precision.

When GPS Initialization Is Needed

The collar may need to re-sync its connection with satellites in the following scenarios:

• When you first take your collar out of the box
• Immediately following a firmware update
• If the collar is turned off for an extended period of time (we recommend that you leave the collar turned on)

If your collar requires GPS initialization:

• The GPS light will blink red once every three seconds
• You will receive an in-app notification
• Your Pet Card will display the following:
  • 
  • 

How to Initialize GPS

To initialize your collar’s GPS:

1. Take your collar outside to an area with an unobstructed view of the sky
   • Avoid heavy tree cover or surrounding buildings
2. Keep the collar outside until the GPS light begins blinking blue, indicating accurate calibration
   • This can take a few minutes, but may take longer in some cases
3. Walk around with the collar during this process
   • This allows you to see the Pet Pin update on the My Map screen
   • Slightly shake the collar to trigger motion sensors

Note:

• The process will still work if the collar remains stationary, but movement helps verify accuracy

After Initialization

• Once the GPS light is blinking blue, the collar has resumed collecting ephemeris data
• The collar is ready for use
• Continued outdoor use and movement will further improve GPS accuracy

Automatic GPS Data Updates

• When plugged in and connected to Wi-Fi, the collar receives satellite position data
• This reduces how often manual GPS initialization is needed
• The collar downloads 2–3 days of advanced satellite data daily

Note:

• Pre-loaded data is not required for GPS functionality
• You may still occasionally receive a GPS initialization notification

If GPS Accuracy Issues Continue

If you are still noticing inaccuracies after initialization:

• Ensure the collar is on the latest firmware
• Check the GPS level on the Pet Card

Expected GPS Behavior:

• Indoors:
  • GPS level should be LOW
  • Collar will not track location
  • Feedback is paused
  • Pet Pin shows last known HIGH GPS location
• Outdoors:
  • GPS level should be HIGH and UPDATING
  • All feedback is active
• Tracking Requirements:
  • Collar must be connected to LTE or Wi-Fi for live updates
  • Even without connection, the collar will still enforce boundaries if GPS is HIGH

Troubleshooting Steps

If GPS remains LOW outdoors:

With collar ON dog:

• Check collar fitment
  • Halo Collar Fitting & Orientation
• Ensure proper positioning for accurate GPS signal
• Adjust GPS signal level settings if needed

With collar OFF dog:

• Take the collar outside and perform a hand test

Additional checks:

• Review collar diagnostics in Collar Settings
• Check the GPS module status
• If you receive a GPS module error, contact customer support
