The CrossCheck® GPRS 1900 Mobile unit is a key component of Trimble's Telvisant Fleet Management System. The unit is a powerful, versatile tool for determining and communicating a vehicle's location and status to the Telvisant Mobile Resource Management platform via a wireless GPRS communication network.

The CrossCheck GPRS unit integrates a GPS receiver, a General packet Radio Service (GPRS) wireless communication system, and computing power in a single, compact enclosure.

• The unit can be used as a standalone device to determine and communicate current vehicle status, including position, speed and direction.
• It can also be interfaced with external accessories and sensors as part of an on-board system to monitor vehicle status and to activate vehicle security peripherals such as ignition lockout or audible alarms.
• The unit can automatically report arrival or departure from defined Job Site or Home Site locations. It also allows various asset utilization calculations such as time spent and distance traveled on job.

The unit mounts conveniently in the vehicle and requires no operator access or involvement.

The EchoLDX™ Messaging Terminal, an optional in-cab accessory, displays and stores text messages received from a dispatcher and enables the operator to send a predefined response message to the dispatcher.
