GPS and Cellular Connectivity

The Savi Locate Sensor is a low-cost, high performance tracking device designed to monitor worldwide intermodal shipments. Interior sensitive and accurate antennas use GPS technology to keep tabs on your cargo from either outside or inside most shipping containers. When GPS satellites are not in view, cell tower triangulation can provide an approximate location, allowing sensors to report in from almost any region of the globe.

Software Integration and Alerting

Savi Locate sensors are integrated with Savi Visibility (in-transit visibility software) to provide end-to-end supply chain monitoring and tracking. When exceptions to pre-defined threshold conditions occurs, sensors send status updates and alerts via cellular networks to Savi Visibility. Sensors are programmed to send updates at varying intervals depending on motion and location to optimize battery life.

Flexibility of OTA Updates

Customers enjoy the flexibility of Savi’s OTA (over-the-air) sensor management capabilities. This enables Savi to change configuration parameters and update configuration on demand. Configurations can be programmed by Savi before shipment or over-the-air once the sensor is deployed in the field.

Affordable and Durable

The low cost of the sensor allows it to be economically feasible as a single use device when return logistics are not an option. The ruggedness of the sensor allows it to be reused many times over if desired. Weatherproof sensors can be attached to the outside of a shipping container, placed within shipping cartons, or affixed to a pallet or asset using double sided automotive tape, screws, nylon wire ties or an optional magnetic bracket.
