Asset tracking system

A system, comprising:

• a transport structure configured to carry items;
• a tracking device coupled to the transport structure, the tracking device including
• a processor,
• a short-range communication module operatively connected to the processor,
• a satellite navigation module operatively connected to the processor,
• a mobile communication module operatively connected to the processor,
• a battery configured to supply sufficient energy to power the tracking device when the battery is at least at a minimum temperature,
• a temperature sensor operatively connected to the processor configured to measure temperature, and
• memory operatively connected to the processor;
• wherein the tracking device is configured to store data in the memory when the temperature measured by the temperature sensor is at or below the minimum temperature;
• and
• wherein the tracking device is configured to communicate the data stored in the memory when the temperature measured by the temperature sensor is greater than the minimum temperature.

A system, comprising:

• a pallet configured to carry items, wherein the pallet includes opposing decks separated by a spacer structure that includes a spacer support;
• a tracking device attached to the spacer support of the pallet, the tracking device including
• a processor,
• a short-range communication module operatively connected to the processor,
• a satellite navigation module operatively connected to the processor, and
• a mobile communication module operatively connected to the processor;
• wherein the tracking device is configured to determine the location of the pallet using the short-range communication module when the tracking device is within a storage facility;
• wherein the tracking device is configured to determine the location of the pallet using the satellite navigation module when the tracking device is outside of the storage facility;
• and
• wherein the processor is configured to use the mobile communication module to at least in part determine the location of the pallet when the tracking device is outside of the storage facility and the satellite navigation module is unable to solely determine the location of the pallet.

A system, comprising:

• a transport structure configured to carry items;
• a tracking device coupled to the transport structure, the tracking device including
• a processor,
• a short-range communication module operatively connected to the processor,
• a satellite navigation module operatively connected to the processor, and
• a mobile communication module operatively connected to the processor;
• wherein the tracking device is configured to determine the location of the transport structure using the short-range communication module when the tracking device is within a storage facility;
• wherein the tracking device is configured to determine the location of the transport structure using the satellite navigation module when the tracking device is outside of the storage facility;
• wherein the processor is configured to use the mobile communication module to at least in part determine the location of the transport structure when the tracking device is outside of the storage facility and the satellite navigation module is unable to solely determine the location of the transport structure;
• and
• a content sensor attached to the transport structure, wherein the content sensor is configured to measure a load carried by the transport structure;
• wherein the content sensor is configured to determine when the transport structure is empty;
• and
• wherein the tracking device is configured to conserve power when the content sensor signals that the transport structure is empty.
