Abstract: A system and method for improving accuracy of a mobile delivery device traversing a route. The system includes a mobile delivery device, a geolocation circuit and an inertial navigation system in communication with the mobile device, and a processor configured to compare accuracy indicators to thresholds to determine when to switch sensing the position of the mobile delivery device between the geolocation circuit and the inertial navigation system.

Abstract: In one aspect, a system for analyzing a route traveled by an item carrier is disclosed. The system comprises a memory circuit and a hardware processor. The memory circuit is configured to store location data points and acceleration data points received from sensors. The hardware processor is configured to receive the location and the acceleration data points from the sensors, store the location and acceleration data points in the memory circuit, and filter the stored location data points to remove a subset of location data points that represent or indicate scatter. The hardware processor is configured to identify the route traveled by the item carrier, filter the stored acceleration data points, identify a state of the item carrier for each of the filtered acceleration data points based on an analysis of the filtered acceleration data points, and verify the identified state of the item carrier.

Abstract: A system and method for determining delivery points associated with particular addresses. In some embodiments, mobile devices can record the geo-location that an item carrier is at when making a delivery of an item. An address association server can receive these locations, organize the recorded geo-locations into clusters, and then calculate accurate delivery points based upon those clusters for a specific address.
