Configuration explained
This section contains additional information and examples.
The CANedge3 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.
Four fences (1-4) and 3 positions (A, B, C)
The geofence state for each of the 3 positions are:
