1. Description
The Industrial Tracker is a general purpose
tracker, designed for GPS tracking on
various applications: bicycles, cars or pets.
It is equipped with GPS and 3-axis
accelerometer, that provides a much more
cost-effective way for service providers to
deploy this for tracking applications than to
use GPRS network.

3. Operation
3.1 Shipping Mode
When industrial trackers leave the factory, they are put into shipping mode, where the sensor is
hibernating without functionality to prevent radioactivity and minimize battery usage. Devices
are delivered in this mode.
3.2 User Mode
This mode is active when the device is in normal
operating mode. To enter user mode from shipping
mode, the user shall place a magnet near the hall
sensor for at least 10 seconds. LED will light
continuous for 3 seconds indicating it is awake.
There are two behaviors in user mode: stationary and
moving.
3.2.1 Stationary Mode
1. Wake up every 15 minutes, and turn on GPS.
2. Analyze satellite status 5 seconds:
a. If the number of satellites is less than 3, and the signal strength is lower than 20, it
will turn off GPS and do LoRa uplink immediately.
b. Or continuous positioning for 60 seconds, and then turn off the GPS and do LoRa
uplink.
3. Set timer for the next round.
4. Enter moving mode when g-sensor is triggered.
a. Trigger condition: continuous triggering over 3 seconds.
3.2.2 Moving Mode
1. LoRa uplinks every minute.
2. Turn on GPS every 5 minutes, and analyze satellites status 10 seconds:
a. If the number of satellites is less than 3, and the signal strength is lower than 20, it
will turn off GPS immediately.
b. Or continuous positioning for 60 seconds, and then stop the GPS.
c. If the GPS position is fixed, the device will never close GPS until entering the
stationary mode.
3. Enter stationary mode when the device is not moving over 30 seconds (g-sensor is not
triggered).

unsigned value α, range 0-7;
position accuracy estimate in m = 2α+2 (max).
The value 7 represents an accuracy estimate of worse than 256m.
Note: If there is no GNSS fix (see sensor status), the Lat and Lon fields contain the last values reported by the
GNSS receiver. If there has never been a GNSS fix acquired, the values may both be 0.
