    "abstract": "Universal Preprocessing GPS SMS Communication Unit (UPCU) was developed as a\npart of the UWI microtracking system. A GSM cellular Short Messaging Service is\nthe main method of delivering tracking information to the central base station.\n  The information includes asset ID, longitude, latitude, altitude, speed and\ndirection as well as the time the message was sent. The design of the unit is\nimplemented as a bi-directional SMS system.",
