Object location tracking system based on relative coordinate systems using proximity location information sources

A system for tracking vehicles comprising:

• one or more servers capable of communicating object location information to a group comprising a plurality of users having user IDs, said group having a group ID, said group being one of a plurality of groups each having a corresponding group IDs and user IDs, said object location information relating to a plurality of vehicles having vehicle IDs, said plurality of vehicles being driven by a plurality of drivers carrying tags associated with driver IDs, each vehicle of said plurality of vehicles being associated with a GPS location information source that provides a GPS location and each tag being associated with a proximity location information source that determines proximity of said tag to said GPS location, the one or more servers being configured to:
• define first level administrative privileges to control user membership in said group;
• define second level administrative privileges to control conveyance of said object location information to said group;
• check the first level administrative privileges before associating a user ID with a group ID of said group;
• check the second level administrative privileges before associating a driver ID and a vehicle ID with the group ID of the group;
• provide one or more interfaces for setting at least one of a zone, an event, or an alert;
• receive a request to set a zone;
• receive a request to set an event based upon said zone and said object location information;
• receive a request to set an alert based upon said event, said alert being associated with an access privilege, said request identifying said group as being the recipient of said alert;
• check the second level administrative privileges before setting said zone, said event, and said alert;
• store said zone, said event and said alert in one or more databases;
• receive object IDs and object location information;
• compare said object IDs and said object location information with said zone and said event to determine whether to send said alert to said group;
• and
• cause the alert to be sent to said group based on said access privilege.

A tracking system comprising:

• one or more servers capable of communicating object location information related to a plurality of first mobile objects having first object IDs and a plurality of second fixed or mobile objects having second object IDs, wherein a first object ID of a first mobile object of said plurality of mobile objects is associated with a first location information source that provides a first location corresponding to first coordinates of said first mobile object within a first coordinate system, and wherein a second object ID of a second fixed or mobile object of said plurality of fixed or mobile objects is associated with a second location information source that provides a second location corresponding to second coordinates of said second fixed or mobile object within a second coordinate system, said second coordinates being relative to said first coordinates based on range or proximity, the one or more servers configured to:
• define first level administrative privileges to control membership of users in a group of a plurality of groups, each group having a corresponding group ID;
• define second level administrative privileges to control conveyance of said object location information to said group;
• check the first level administrative privileges before associating a user ID with a group ID of said group;
• check the second level administrative privileges before associating a first object ID and a second object ID with the group ID of said group;
• provide one or more interfaces for setting zone, event, or alert for the group;
• receive a request to set a zone for the group;
• receive a request to set an event for the group based upon said zone and said object location information;
• receive a request to set an alert for the group, said request identifying said group as being the recipient of said alert;
• check the second level administrative privileges before setting the zone, event, or alert;
• store the zone, event and alert in one or more databases;
• receive object IDs and object location information;
• compare object IDs and object location information with the zone and event to determine whether to send said alert;
• and
• cause the alert to be sent to said group.
