Information about position signals and virtual fences

GNSS and Coverage

• Interference: GNSS signals can be weakened by roofs, mountains, and dense forests. Inside buildings, the signal may be completely lost.
• Not the same as mobile coverage: The collar uses GNSS for positioning, not mobile networks. You can have good mobile coverage but still have poor GNSS reception.
• Slow updates after signal loss: If the collar has been without GNSS for a while (e.g., inside the barn), it may take time before it gets an accurate position again. The collar will wait to activate the virtual fence until it receives a good GNSS signal. The dots on the map will turn green once the fence has been activated.

How GNSS affects the fence

No mobile coverage required: The fence works as long as the collar has power and a GNSS signal.

Temporary pause with weak signal: If the GNSS signal becomes too weak, the fence is temporarily paused to avoid giving animals sound signals or shocks in the wrong place. It will automatically reactivate once the position is stable enough.

Optimal placement of the fence

Monil's collar uses GNSS from multiple systems, such as GPS, Galileo, GLONASS, and BeiDou, to ensure the best possible GNSS coverage. For optimal accuracy:

• Avoid placing fences near tall buildings, mountain slopes, or dense forests (keep at least a 10-meter distance).
• If distance is not possible, use exclusion zones with a good margin around obstacles to avoid incorrect positioning.
