custom firmware - advanced

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. 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
Magnetic Variation:
Applications: Vehicle Tracking
- This option outputs degree of magnetic variation & magnetic heading, which is useful for navigation and determining direction.
- Default: Disabled
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
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
Navigation mode:
Applications: Vehicle Tracking, Personal Tracking, UAV
You can choose different configurations based on your application e.g. :
- Vehicle
- Pedestrian
- Aircraft
- Air balloon
