2. Last Position Retention:

You can continue to the output the last position in the event of losing GNSS fix.
Default: Disabled

Applications: Asset Tracking, Vehicle Tracking

3. Magnetic Variation:

This option outputs degree of magnetic variation & magnetic heading, which is useful for navigation and determining direction.
Default: Disabled

Applications: Vehicle Tracking

4. Geo-fencing:

Allows you to set a radius value around a target position, and informs the user if the receiver is inside or outside this predefined boundary.
Default: Disabled

Applications: Pet Tracking, Personal Tracking, Security

5. Distance Calculation:

You can calculate direct distance between current location and other points. This calculation is done by the module itself and can decrease load on the users MCU.
Default :Disabled
