How accurate is the location?

The eShell combines different technologies to provide the location of the goods. GPS technology requires direct exposure to the sky to receive signal from satellites. The signal can cross glass, plastic and thin surfaces, but when the sensor is under solid ceilings it cannot get an accurate location, like in underground parkings, factories, or under a stack of containers. Shellock overcomes this limitation by additionally triangulating the location based on cell-towers and wifi networks available in the area. With this combination of technologies we provide an accurate location under most cases throughout the journey, all along the supply chain.
