Abstract
Abstract A spread spectrum rf communication system relays mission signals from a base computer to each of a plurality of vehicle controllers (VCONs) that are positioned in the passenger compartments of respective vehicles on a test track. The VCONs are coupled to the operating controls of the vehicles for moving the controls in response to mission signals from the base station. Also, the VCONs communicate status reports via the communication system to the base station, so that the base station coordinates the control of the vehicles.
