1. A vehicle-mounted device, comprising: an inertial measurement unit (IMU) comprising six acceleration or velocity measuring devices; a receiver configured to receive satellite-sourced positioning signals; at least one camera each positioned to obtain images of an area exterior of the vehicle; a control system coupled to said IMU, said receiver and said at least one camera, said control system being configured to re-calibrate said six acceleration or velocity measuring devices using signals obtained by said receiver; and a communication system coupled to said control system and that communicates the images obtained by said at least one camera or information about objects in the images obtained by said at least one camera to a location separate and apart from the vehicle, wherein said control system includes a processor and is configured to provide a location of said at least one camera based on data from said IMU corrected based on data from said receiver and positioning correction data derived from satellite-sourced positioning signals and to provide a direction in which said at least one camera is imaging based on data from said IMU corrected based on data from said receiver.
