Zusammenfassung:	A freight tracking system uses a tracking device hidden in the taillight of a vehicle and a remote device located somewhere else on the vehicle. The remote device determines the position of the vehicle using information received from global navigation system satellites and communicates this wirelessly to the tracking device using a mesh network. The tracking device comprises a 9-axis IMU (inertial measurement unit) that uses a fusion filter and a calculation involving digital quaternions to determine inertial information. The vehicle position is compared to geographic boundary information to determine if the vehicle might have gone outside of geographic boundaries. If so, a geofencing alarm is triggered. The device has a tampering detector to ensure that the device is not opened. The alarms, vehicle position, and time information can be communicated to an internet-connected database using a cellular wireless device.
