Your Geofence might be drawn too close to the cart path, leaving insufficient space for carts to safely stop and allow players to exit. This will not only create logistical challenges but also lead to frequent geofence breaches—instances where the system incorrectly flagged a cart as entering restricted grass. These breaches were not due to rule violations but rather a combination of physical layout and environmental interference.
The original geofence boundary was set so tightly against the cart path that even minor deviations in GPS signal could trigger a breach. This can become especially problematic when carts were parked under tree canopies, a common occurrence on many golf courses. The dense foliage disrupted the GPS signal, causing what is known as GPS drift—a temporary inaccuracy in the cart’s reported location. Instead of showing the cart as stationary, the system would occasionally display it as having moved a few yards into the restricted area, resulting in a false breach alert.
GPS signals travel from satellites to the tag on the cart through the atmosphere. When these signals pass through dense tree canopies, they can be scattered, reflected, or delayed. This phenomenon is particularly noticeable in areas with heavy foliage, such as under large trees near cart paths or greens. The result is a momentary "jump" in the GPS location, which the geofencing system interprets as movement into a restricted zone.
This issue is not unique to any one course or system—it’s a occurrence in GPS-based tracking. The key to mitigating it lies in drawing geofences with a buffer zone that accounts for natural signal variability. By increasing the distance between the cart path and the restricted area, the system gains a margin of error that absorbs minor GPS drift without triggering false alerts.
To address the issue, we suggest repositioning your Geofence boundaries further away from the cart path, creating a wider buffer zone between the path and the restricted grass. This will accommodate the natural GPS drift that occurs when carts park under trees or in areas with signal interference.
The updated geofence now provides ample space for carts to stop safely, allowing players to exit without risk of triggering a breach. More importantly, the added buffer acts as a safety net for GPS signal fluctuations. Even if a cart’s location temporarily shifts due to foliage interference, the system will no longer interpret this as a violation, significantly reducing false alerts.
After the adjustment, we advise you to monitor the area over the next few days. This follow-up period allows for real-world testing under various conditions—different times of day, weather patterns, and cart usage levels. The goal is to confirm that the revised geofence effectively prevents breaches while still maintaining the intended course protection.
It’s important to note that geofencing is not a one-time setup. Environmental factors such as tree growth, changes in cart usage patterns, or even seasonal foliage changes can impact GPS signal quality over time. Regular reviews and minor adjustments—when needed—ensure that the system remains both effective and reliable.
To help all course operators avoid similar issues, here are key recommendations for maintaining high-performing geofences:
Always leave a minimum buffer of 5–10 feet between cart paths and restricted zones. This buffer accounts for GPS drift and ensures that carts can stop safely without triggering alerts.
Identify areas with heavy tree cover, tall shrubs, or other signal-blocking features. These locations are more prone to GPS drift. Consider adjusting geofences in such areas or using alternative placement strategies.
Monitor geofence performance during busy rounds or high-traffic periods. This helps identify whether the system is handling real-world conditions effectively.
The TrackMap feature in the Tagmarshal dashboard provides detailed visualizations of cart movements and breach events. Use this tool to spot patterns, validate adjustments, and make data-driven decisions.
If you notice recurring breaches in areas where carts are parked safely, reach out to the Tagmarshal support team or customer success team. They can analyze breach logs, assess signal conditions, and recommend targeted adjustments. Alternatively, please have a look at our training material on adjusting and improving your Geofences and settings.
Geofencing is a powerful tool for course management, but its success depends on smart design and ongoing attention. With the right buffer zones, regular monitoring, and timely support, every course can achieve a balance between turf protection and player convenience.
