Configuration explained

This section contains additional information and examples.

The CANedge1 GNSS supports up to four circular geofences with configurable radiuses1. When enabled, the device continuously calculates if the current position is inside or outside each of the configured fences. See GnssGeofence signals for more information on the generated output.

Note

Calculating the result of geofences on the device allows for the signal to be used as Control Signal.

Examples

Four geofences are configured as illustrated below.

The geofence state for each of the 3 positions are:
