custom firmware - advanced

1. One-Sentence:
   Applications: Security, Wearables, etc.
   • Output customized sentence in Binary or ASCI mode, or simplify NMEA output to reduce MCU load.
   • Other customizations available per customer’s requirement or algorithms.
   • Default: NMEA
2. 2. Last Position Retention:
   Applications: Asset Tracking, Vehicle Tracking
   • You can continue to the output the last position in the event of losing GNSS fix.
   • Default: Disabled
3. Magnetic Variation:
   Applications: Vehicle Tracking
   • This option outputs degree of magnetic variation & magnetic heading, which is useful for navigation and determining direction.
   • Default: Disabled
4. Geo-fencing:
   Applications: Pet Tracking, Personal Tracking, Security
   • 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
5. Distance Calculation:
   Applications : Aviation
   • 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
6. Navigation mode:
   Applications: Vehicle Tracking, Personal Tracking, UAV
   You can choose different configurations based on your application e.g. :
   • Vehicle
   • Pedestrian
   • Aircraft
   • Air balloon
