After preparing the map and setting up the beacons, it's time to evaluate the positioning accuracy.
If there are any issues during navigation, please make sure to record and report them.
To test the positioning accuracy:
- Move around the location and make sure that the blue dot on the map shows your correct position.
- The expected average position error for correctly set up beacons is 3-3.5 meters. If the positional error is above this level, please report it.
- Report any positioning issues, such as point drift, jumps, or level estimation errors.
- Check the visibility of each beacon on your map using the app's debugging mode.
a. The beacon should appear in debugging mode.
b. The signal from the beacon should be above -80dBm from 1.5-2 meters.
c. The beacon's battery should not be low or zero. The battery should be replaced every 3-6 months depending on the beacon's power consumption. Choose the maintenance cycle according to your beacon power settings.
To report your issues, record logs over your location:
- Record routes that are longer than 100 meters or last longer than 30 seconds.
- Provide ground truth data by recording logs over a polyline (link).
- Walk through:
a. Expected areas of navigation (corridors, halls, etc.).
b. Problematic areas.
c. The outer contour of the location - a test for correct beacon placement.
To better understand the situation on your end, we usually ask for ground truth data, such as recording logs with checkpoints. With this data, our experts can find the best suitable settings for your location.
