Auto calibration task is launched on one of these conditions (assume calibration is enabled in configuration):<br>
Auto calibration task is launched on one of these conditions (assume calibration is enabled in configuration):<br>
1. Every time device turns on, it checks whether it was previously calibrated and has calibration stored in flash. If device has no calibration in flash, auto calibration task is started.<br>

2. Device calibration was previously disabled by configuration and now is enabled.<br>
2. Device calibration was previously disabled by configuration and now is enabled. If Full calibration is already stored, it will not be overwritten.<br>
3. SMS “auto_calibrate:set” is received. Note: SMS response is sent after calibration has been acquired.<br>
3. SMS “auto_calibrate:set” is received. Note: SMS response is sent after calibration has been acquired.<br>
This SMS triggers an SMS response to be sent. Response is sent when calibration is acquired. When 1 hour passes without successful calibration, failed SMS response is sent.<br>

4. Calibrated device’s mean axes of set interval differ more than set amount from desired (0,0,1) calibration is considered inaccurate. Calibration is deleted from flash and auto calibration task started.<br>

HDOP and PDOP values are checked before start calibration process. If current HDOP or PDOP values are less than 10, auto calibration will not start.
After auto calibration task has been started, it will go on indefinitely until satisfactory calibration is acquired.<br>
