Orbital Sciences Corp. has been awarded a $9 million contract to install a vehicle management system for tracking the fleet of buses operated by Metropolitan Nashville Public Schools, Orbital announced July 23.

Orbital’s Transportation Managements Systems division will install its OrbCAD system, an integrated software system that uses satellite-delivered positioning information to track vehicles along prescheduled routes. The system also will provide two-way voice communications and video cameras.

Installations at the organization’s control center and on the fleet of 685 school buses and administrative vehicles are scheduled to be completed in three phases over a 36-month period.
