1. A system for controlling speed of a moving vehicle, comprising:
- a portable relocatable global positioning device in communication with at least three global positioning satellites, wherein the global positioning device has a global positioning processor for computing a current location of a moving vehicle, and wherein the current location comprises a latitude, a longitude, and an elevation of the moving vehicle;
a portable relocatable speed limit processor in communication with the global positioning device and with a vehicle processor on the moving vehicle;
a database of legal vehicle speed limits in data storage in communication with the speed limit processor, wherein each legal vehicle speed limit in the database is associated with a defined longitude, a defined latitude, and a defined elevation;
computer instructions in communication with the speed limit processor for instructing the speed limit processor to match the current location of the moving vehicle with a legal vehicle speed limit for a defined location using the database of legal vehicle speed limits;
computer instructions in communication with the speed limit processor for instructing the speed limit processor to instruct the vehicle processor to modify a real time speed of the moving vehicle to match the legal vehicle speed limit for the defined location;
a power supply for providing power to the global positioning device and the speed limit processor; and
wherein the speed limit processor communicates a legal vehicle speed limit for the defined location from the database to the vehicle processor, and wherein computer instructions in communication with the vehicle processor instruct the vehicle processor to compare the real time speed of the moving vehicle to the legal vehicle speed limit for the defined location and control power to the moving vehicle to maintain the moving vehicle at or below the legal vehicle speed limit.

Abstract
A system, a method and device for controlling speed of a moving vehicle, using portable and repositionable global positioning devices, speed limit processors, and a database of legal vehicle speed limits is in communication with the speed limit processor. Computer instructions instruct the speed limit processor to match the current location of the moving vehicle with a legal vehicle speed limit for a defined location using the database. The speed limit processor communicates the legal vehicle speed limit to the vehicle processor to control the speed of the moving vehicle.
