AT03821 GPS Tracker - Wing Configuration

In this configuration, the GPS Tracker board has no on-board processor or related components mounted, and is designed to be attached to a SAM D20 Xplained Pro board on the EXT1 and EXT2 headers. The USB cable must be plugged into the SAM D20 Xplained Pro to correctly power the main processor. If not inserted, the application will not run correctly. GPS and GSM antennas should be attached to the two connectors on the board and placed with a clear line of sight to the sky to ensure best possible signal reception. A full-sized SIM card should be inserted into the SIM receptacle with the board unpowered.

Once all the hardware is configured according to Hardware Setup, the code can be loaded into the device. On startup, the system will initialize all hardware and begin listening for UI events and new GPS or GSM data. The GPS Tracker can be configured to send alert SMS messages to one or more recipients each time the tracker enters or exits a rectangular set of GPS coordinates. Every minute, the Geofence service will check the current GPS location and compare it against the set of stored coordinates. If the tracker exits or enters the Geofence area, alert messages will be sent to the list of phone numbers read from the inserted SD Card.

This GPS Tracker design provides a complete solution for applications like logging positional tracking of people and assets in real time, tracking for theft prevention, historical logging for navigation, and other related operation that employs the service of GPS.
