OEM Data Delivery introduces the ST-950 service tracker with GPS and radio communications. The system was developed for tracking equipment activity at utility construction sites, and during service calls, so that power take-off credits can be obtained quickly for fuel used at the worksite, as opposed to on-highway. The ST-950 also generates a wide range of customized data logs, including machine hours, equipment location, and idling vs. work.
