The CrossCheck GSM mobile communicator is a tightly integrated device that combines a Global Positioning System (GPS) receiver, Global System for Mobile Communications (GSM) technology and IQEvent Engine (IQEE) firmware in a single module. In addition, the size and power consumption of the GPS components are significantly reduced through the use of Trimble's new FirstGPS technology. The move to this single, wireless, positioning and communications unit brings increased reliability as well as a reduction in cost and installation time to operators.
Trimble's CrossCheck GSM operates over the standard wireless GSM network. It sends GPS data and messages from the mobile unit to a base station running Trimble's FleetVision® software. The CrossCheck GSM can be used in a standalone mode or interfaced to external accessories and sensors to operate as part of an on-board system. These include a Mobile Data Terminal (MDT) that forms the interface with the driver enabling the exchange of messages, the generation of manual event reports and an (optional) telephone handset (hands-free or handheld) for voice communications. Because of the CrossCheck GSM's flexibility, it can be adapted to virtually all fleet applications from armored car transport to limousine service and from utility fleets to construction equipment.
The system's IQEE firmware supports intelligent, automated monitoring and reporting of vehicle activity and status. An alert report, for example, automatically sends the vehicle's location and status to the operations center when specific events occur. This status report can cause the operations center to respond by remotely activating the vehicle's security systems, such as door locks, ignition lockout, sirens, lights or take other appropriate actions.
